The concept of play in the steering mechanism
In relation to the steering of a car, play is the amplitude of rotation of the steering wheel at which the car continues to move in the same direction.
A special rod, one of the steering elements, does not fit tightly to other parts, forming a gap. Due to this, the elements of the mechanism do not wear out during friction. The traffic rules set the maximum gap to no more than 10 degrees. Exceeding this value makes the car impossible to operate and requires immediate elimination.
Traffic rules of the Republic of Belarus 2022
The Traffic Rules given in this section are the current Traffic Rules of the Republic of Belarus 2022, improved with hyperlinks and pop-up help windows (changes and additions to Decree No. 349 of the President of the Republic of Belarus dated August 10, 2015 and subsequent decrees are taken into account).
The source of information is the National Register of Legal Acts of the Republic of Belarus. Reference data bank of legal information of the Republic of Belarus.
The Traffic Rules highlight special active elements. The active element of the text in the traffic rules of the Republic of Belarus is an indication in the text of the Rules to another paragraph of the Rules, to the number of the road sign or to a term and other instructions. The graphical active element in the traffic rules is all images of road signs and road markings, as well as images of road traffic lights.
In the Traffic Regulations of the Republic of Belarus, a hint window and a hyperlink are attached to the active element.
The traffic rules of the Republic of Belarus contain implicit terms. Such an implicit term of the traffic rules, for example, is the term “Congestion”, and its definition: “Congestion is a cluster of other vehicles stopped on the roadway” is obvious from clause 53.2 of the traffic rules:
"53.2. when a vehicle is forced to stop on the roadway and in places where stopping is prohibited, with the exception of stopping the movement of the vehicle due to the accumulation of other vehicles stopped on the roadway (hereinafter referred to as a traffic jam).”
Note that additional emphasis on implicit terms allows you to better understand the Rules of the Road! We found about 20 such implicit terms in the traffic rules of the Republic of Belarus.
Interactivity in the online traffic rules of the Republic of Belarus is ensured as follows:
Pop-up help windows may also use implicit traffic rules terms, various traffic rules groupings and creative traffic rules memos.
Closely related to the Belarus traffic rules section is another section of the website “Road Rules 2020” - Express tests. Express tests are a new type of testing according to the Belarusian Traffic Rules. This type of testing covers all points of the traffic rules and tests the test taker for accurate knowledge of the important requirements of the Rules. At the same time, express tests for traffic rules are quick tests that do not take much time during the testing process. Express tests are quick and easy. A quick question in electronic form is a high-tech, informative and educational question. Compared to classic traffic rules testing of the form “Question - Illustration (if any) - Answer options", express testing is an alternative test and has its advantages.

A little information on the traffic rules of the Republic of Belarus:
There are not enough illustrations in the decrees of the President of the Republic of Belarus on traffic rules. In 2009, a scientific and practical publication appeared - a commentary on the Traffic Rules, 560 pages in size with black and white illustrations.
The commentary to the Traffic Rules does not currently reflect the important changes made to the Traffic Rules by Decree of the President of the Republic of Belarus dated October 13, 2014 No. 483 “On Amendments and Additions to the Traffic Rules.”
Causes of backlash
After a long period of operation, the working surfaces of the roller, bearing, bushing, washer, bipod shaft and its T-shaped groove, and the head of the adjusting screw become unusable. Thus, the gaps in the steering device increase, while the car is moving, extraneous knocks and vibrations appear, the wheels become unstable and wobble. Initially, a gap appears at the point of contact between the roller and the worm; subsequently, simultaneously with the steering shaft, an axial displacement of the worm occurs.
When traveling at high speed, the car becomes uncontrollable, which can lead to serious consequences, including an accident.
The main reason for the occurrence of backlash is the disgusting condition of the roads. The car's suspension takes on the bulk of the load, which is directed to the wheels, but some of it still falls on the steering parts. The situation is aggravated by the use of low-quality rubber, which significantly reduces the service life of the steering rod and suspension.
Loosening the nut
The “innocent” cause of the malfunction is the loosening of the steering wheel nut. Adjustment is performed by tightening the screw in the end cover of the steering mechanism. First, the decorative element of the fastening casing is removed, then the nut is tightened with a socket wrench of the required diameter.
If an airbag assembly is installed in the car trim (this applies to modern cars), it must first be dismantled to provide access to the nut. Work is carried out with the battery terminals disconnected in order to comply with safety precautions.
Important! If you do not tighten the fastening nut in a timely manner, this will lead to wear of the splines in the place where the steering wheel is attached, resulting in the steering wheel turning and loss of vehicle control.
Wear of rod ends
A more dangerous cause of play in the steering is wear of the rod ends. Due to the fact that these elements operate in difficult conditions, being constantly exposed to dirt and water, they deteriorate faster. As a result, the axial and radial clearances in the ball joint of the tip increase, it falls apart and driving the car becomes impossible. To avoid the consequences of such a malfunction, you should immediately contact service to replace parts.
Also, there are several reasons for the formation of free play, hidden in the design of the steering system.
- collapsed wheel bearing;
- loosening or improper tightening of the steering wheel nut and adjusting rods;
- wear of the ball joint;
- depreciation or breakage of hinges, splines, driveshaft joints;
- excessive gap between the toothed bar and the gear, or their wear;
- unsuitable hydraulic oil.
Steering rod faults: how to detect them and how to deal with them?
Tie rods are an important part of the steering mechanism. Any malfunctions with them are not problems from the “car won’t drive” series.
This is a direct threat of steering failure while the car is moving, which means a direct path to an accident. Therefore, the condition of the steering rods must be constantly monitored, and if there are suspicions about the presence of malfunctions, in no case should they be ignored. Timely replacement of steering rods and ends will help avoid many unpleasant surprises on the road.
Tie Rod Functions
Tie rods transmit force from the steering wheel to the hub pivot arms to turn the wheels. Moreover, they are part of the steering linkage, determining the angle of rotation of each wheel (when turning, the wheels move along different radii).
Main problems with tie rods
The tie rods themselves are metal rods, which are quite difficult to damage. They can only be bent by “catching” the wheel on a stone or other obstacle.
Much more often there are malfunctions associated with:
- Hinges. These parts are located at the ends of the steering rods. Most often, the cause of failure is excessive wear of the liner (or rubber bushing) or the spherical surface of the pin (damage to the thread, cone, surface due to corrosion or unprofessional installation/disassembly).
- A cotter pin securing the castle nut. Incorrect installation of this small and not particularly significant, at first glance, part can lead to irreparable consequences: the cotter pin falls out -> the nut loosens -> the finger loses tight contact -> the steering linkage loses its geometry -> it is impossible to drive the car.
- Anthers or a hinge cover. When the boot breaks or the cover moves from its seat, the hinge becomes dirty and, as a result, wears out faster.
- Bushings, threaded parts of rods and other parts of the toe angle mechanism. They may become corroded or damaged when driving in poor road conditions.
Signals about problems with steering rods
Simple attention to how the car “behaves” on the road will allow you to notice the malfunction in time. Large free play of the steering wheel, as well as extraneous sounds (usually knocking) when turning are a sign of problems with the hinges. Deviation from the selected line of movement, as well as from the specified turning radius, may indicate that the hinge has fallen apart or the tips have worn out. The main thing is to notice the problem in time so as not to suddenly lose control of the car while driving.
Trouble-shooting
The vast majority of steering rods and joints are disposable, that is, they cannot be repaired. Only replacing parts in case of detection of malfunctions will guarantee that the car will not let you down at the most inopportune moment.
How to diagnose a malfunction?
Steering play is especially pronounced when driving on a straight road at high speed. A sign of a breakdown is a knocking sound when the steering wheel is turned sharply. An increasing knocking sound while driving on uneven terrain indicates damage to the steering ends and rods. Knocking into the steering wheel indicates a faulty steering bar.
If the steering wheel “beats” when driving, this indicates a failure of the ball joint or steering ends. The cause may also be wear of the bushing, bearing, or crosspiece.
A noise of unknown origin when turning the steering wheel indicates the need to check the fluid level.
A change in the given direction of movement of the car with the steering wheel in a straight position, the feeling that the car is “pulling” to the side, indicates an unbalanced camber - wheel toe-in.
The steering wheel turns jerkily if the steering bar is jammed. If it turns with force, you need to check the operation of the amplifier.
To find out if there are problems with the steering, you should do a small check:
- Start the engine and leave it idling.
- At the same time, check the operation of the hydraulic booster.
- Align the front wheels parallel to the longitudinal axis of the car.
- Turning the steering wheel in one direction and the other, record the moment when the front wheels begin to move. Play (free play) will be the gap that the steering wheel goes through before the wheels move.
To more accurately determine the gap, use a special backlash meter.
VEHICLE LAYOUT
There are three types of car layout:
- Front-engine - a car layout in which the engine is located in front of the passenger compartment. It is the most common and has two options: rear-wheel drive (classic) and front-wheel drive. The last type of layout - front-engine, front-wheel drive - is now widely used due to a number of advantages over rear-wheel drive: - better stability and controllability when driving at high speed, especially on wet and slippery roads. — ensuring the necessary weight load on the drive wheels. - lower noise level, which is facilitated by the absence of a driveshaft. At the same time, front-wheel drive cars also have a number of disadvantages: - at full load, acceleration on hills and on wet roads is reduced; — at the moment of braking, the weight distribution between the axles is too uneven (the wheels of the front axle account for 70%-75% of the car’s weight) and, accordingly, the braking forces (see Braking properties); — the tires of the front driving steered wheels are more loaded and therefore more susceptible to wear; - drive to the front wheels requires the use of complex narrow joints - constant velocity joints (CV joints) - combining the power unit (engine and gearbox) with the main gear complicates access to individual elements.
- The mid-engine layout—the engine is located between the front and rear axles—is quite rare for passenger cars. It allows you to get the most spacious interior with given dimensions and good distribution along the axles.
- Rear-engine - the engine is located behind the passenger compartment. This arrangement was common on small cars. When transmitting torque to the rear wheels, it made it possible to obtain an inexpensive power unit and distribute such load along the axles, in which about 60% of the weight fell on the rear wheels. This had a positive effect on the vehicle's cross-country ability, but negatively on its stability and controllability, especially at high speeds. Cars with this layout are currently practically not produced.
Eliminating play in the steering
To adjust the steering, you will need the usual set of simple tools to adjust the mounts. All troubleshooting work is carried out in a garage with an inspection pit, overpass, or with a lift.
If the playmeter or manual diagnostics show unsatisfactory results, proceed to the following actions (the help of a partner will be required):
- Determine the source of the knock and check the operation of the suspensions.
- Try to tighten the steering bar.
- Holding the steering wheel, turn it from side to side within the limits of free play, while simultaneously observing the operation of the driveshaft near the rack and ball joints. And also monitor the tightness of the mating rods, which must fit exactly into one another.
- If the steering rack is not damaged, turn the adjusting screw to eliminate the play in the rack.
- Free play in the cardan shaft most often occurs due to lack of lubrication. It can be eliminated only by replacing the part.
- Backlash at the junction of the rods is eliminated by spot welding, which holds the parts together during operation.
- Repair or replace ball ends if necessary.
- Pay special attention to the serviceability of the tips and the integrity of the rubber boots.
- Check whether the steering wheel play has been eliminated.
Defective parts
The parts of the disassembled rack must be wiped of oil, cleaned of deposits and carefully inspected. Repair kits usually include only rubber seals and fluoroplastic bushings with rings. This may not be sufficient for every case.
Carefully inspect the surface of the gear rod - there should be no damage or signs of wear.
Pay special attention to the working area - the teeth and the part of the rod that comes into contact with the rings, seals and bushings. Any damage, corrosion, risks and scuffing will lead to rapid wear of the seals and rack leakage
Deep corrosion of the rack rod.
Such a detail cannot be installed. There should be no cracks, nicks, chips or deep wear on the helical teeth of the drive shaft gear. It is dangerous to install a shaft with such damage - the rack may jam in motion.
A common cause of knocking noises in the rack is wear of the pressure bushing. The working surface of the part must be smooth, without signs of pressing or scoring. The pressure bushing is usually not included in the rack repair kit, but for many cars it can be purchased separately.
Wear of the pressure sleeve - the fluoroplastic insert is pressed through
Severely worn and damaged rack parts cannot be restored in a garage. If problems are found during troubleshooting, contact specialized service stations for help. There they can restore the rack shaft and rod using professional equipment.
Management problems
Control problems, along with brake failures, are the worst things that can happen to a car in motion. The real harbinger of such problems is steering play. Let's figure out what it is and how to protect yourself.
So, play is a flaw in the steering. It occurs due to problems with the steering rack, or the calibration of the steering wheel itself. Essentially, this is a poor reaction of the wheels to turning the steering wheel, which is expressed in the form of a reserve.
To put it simply: if you turn the steering wheel to the side, but the wheels do not react immediately, this is the same play. It’s worth noting right away that many manufacturers provide a slight free play of the steering wheel, without “hooking” the wheels themselves. You can find out the corresponding freewheel parameters in the technical documentation of your vehicle.
What is the penalty for steering wheel play?
Article 12.5 of the Code of Administrative Offenses of the Russian Federation threatens a fine of 500 rubles for this, and a traffic police inspector who discovers a faulty car is obliged to stop using it and send it to the impound lot.

Other troubles
In addition to backlash, you should be attentive to other troubles associated with turning and steering:
- Increasing effort. If you notice that you need to apply more and more force to the steering wheel in order to make a turn, then this is also a sign of a problem. This happens due to wear of the rack or gearbox.
- Spontaneous deviation. Let's assume that you parked your car in the evening, leaving the steering wheel strictly in the center. In the morning, getting into the cabin, you noticed that it was tilted, while the wheels remained straight.
- Leaks. Liquid can leak both from the rack seal and from the power steering barrel. You can find them under your car, or during a self-inspection in a pit.
If one of these aspects is detected, we recommend immediately contacting the service and checking the mechanisms. One diagnostic that you pay for can save not only your future budget, but also the health and life of you and your passengers.
When can and when can they not check for faults?
The list of these faults for 2022 is contained in two documents:
- Appendix to the Basic Provisions for the Admission of Vehicles to Operation.
- Appendix No. 8 to the Technical Regulations On the safety of wheeled vehicles.
The second list is broader, the status of the Technical Regulations is higher than the Basic Provisions, and the Technical Regulations were adopted later. Theoretically, both traffic police and drivers should be guided by it regarding the technical condition of the car.
To bring the two documents into compliance, amendments to the traffic rules were prepared 3 years ago, which remain shelved. Knowing the enthusiasm of officials, which awakens exclusively before the New Year, it is quite possible that the relevant amendments will nevertheless be adopted by the end of the year, followed by the adoption of amendments to the Administrative Code.
In the meantime, they are punished only for malfunctions that are mentioned in the Basic Provisions for Admission, except for tinting, the requirements for which are prescribed in the Technical Regulations.
On the one hand, this is impossible. For example, how do you check that the parking brake is holding a vehicle with a full load on a 16% grade? Every morning, look for a 16% slope, load the car with sandbags, pull the handbrake and see: will the car roll or not? Or buy a brake testing stand?
- It is possible to check the play in the steering, which should not exceed 10°, without instruments, but the required measurement accuracy cannot be obtained.
- It is also impossible to check the cleanliness of engine exhaust without instruments.
- But it’s easy to check whether the wheels are worn down to the wear indicators, just as it’s easy to make sure there are no leaks from the engine, gearbox, gearbox and other components.
Traffic police inspectors have a rather cool attitude towards monitoring the technical condition of a car.
The thing is that there is no clear description of the procedure, and the inspector can only improvise, disguising his actions, which supposedly comply with the law.
In full accordance with the Administrative Regulations of the Traffic Police, an inspector can stop a driver in 4 cases:
- Visual detection of signs of malfunctions falling under Article 8.23 and 12.5 of the Administrative Code.
- Participation of a vehicle in an accident.
- Availability of guidance on road accidents, theft, crimes, etc.
- Carrying out activities as directed by management.
If the inspector sees a malfunction after stopping, for example, to check documents, he can also check the technical condition of the car
And here I would like to draw your attention: if the car was not involved in an accident, there are no orientations and no measures are taken, then the inspector does not have the right to take any action to detect malfunctions. For example, the driver cannot be required to turn on the rear fog light to check whether it works or not.
He will charge the driver under Part 1 of Article 12.5 of the Code of Administrative Offenses with a fine of 500 rubles, and he will be released on all fours, since the malfunction was discovered on the way. But this approach of inspectors to punishment for malfunctions does not meet the requirements of the law.
If the driver checked the condition of the car before leaving, then there can be no claims against him.
- Firstly, when leaving the parking lot, he did not know that a malfunction would occur on the way, and could not have known. That is, the driver’s actions are not to blame.
- And if the driver discovers a malfunction on the road, then, in accordance with the traffic rules, he can move to the place of parking or repair. That is, going to a car repair shop or to your home after discovering a malfunction along the way does not constitute an offense at all.
The most striking example is a burnt-out light bulb in a headlight. If the driver checked the functionality of the headlight before leaving the parking lot, and the light bulb burned out on the road, then there is no reason to punish the driver when driving to the parking lot or repair site.

Tolerance
As we have already said, automakers set the permissible amount of play. It is usually 2-3 millimeters, or degrees of slope. They are necessary so that the control mechanisms are not under constant pressure and, accordingly, last longer due to less wear.
The norm is prescribed in the technical documentation, but it may be different for different vehicles. Usually for buses and trucks it is slightly higher, again, due to the greater load on the steering rack. For passenger cars it is limited to a couple of degrees.
List of faults and conditions under which the operation of vehicles is prohibited
Wheels and tires 5.1 Tires of passenger cars have a residual tread height of less than 1.6 mm, trucks - 1 mm, buses - 2 mm, motorcycles and mopeds - 0.8 mm. Note For trailers, standards for the residual tread height of tires are established, similar standards for tires of vehicles - tractors.5.
2 The tires have external damage (punctures, cuts, breaks), exposing the cord, as well as delamination of the carcass, peeling of the tread and sidewall. 5.3 There is no fastening bolt (nut) or there are cracks in the disk and wheel rims, there are visible violations of the shape and size of the mounting holes. 5.4 Tires do not match the vehicle model in size or load capacity.5.
Examination
Checking the play can be carried out either independently or with the help of service specialists. In order to find out the value yourself, you will need a ruler, some kind of marker or chalk and the attentive eye of an assistant.
- Set the steering wheel to a normal, straight position. You can determine it using a ruler with a water capsule, the so-called level.
- Having placed the steering wheel, we make a mark at the very top of it. We place a regular ruler in front of the steering wheels. We compare the mark with the reading on the ruler. Let's say we got the mark to be at 15 centimeters.
- Then, we slowly turn the steering wheel, counting the centimeters by which we have deviated. For example, we rotate it to the left, which means our mark will approach 14 centimeters and further.
- Our observer watches the wheels and signals when they have moved. When we received his command, we stop the rotation and record the indicator. Let's say our mark remains at 13.5 centimeters. This means the play is 1.5 centimeters.
- This work can be ideally done using a protractor. You just need a big one, something like what engineers and architects use. It can be purchased in the office supply department. The principle is the same, but the data obtained will be in degrees, which suits us better.
At a service station, such work is carried out using a special device - a backlash meter. This is a small computer that connects to the steering wheel and calculates the deviations itself. Naturally, it is much more accurate and gives a better picture of the situation and the necessary corrections. With its help, the total play of the steering wheel is calculated. If the documentation does not allow it, then we need to move on to correction.
Removing the gearbox
The design of the gearbox does not allow it to be repaired without removing it from the vehicle. In order to remove it, you must:
- Disconnect the tie rod ends from the gearbox. First, they are uncoiled, then the nuts are unscrewed with a 22 wrench and the tips are pressed out using a special puller.
- Unscrew the clamp securing the steering shaft to the gearbox.
- Remove the three bolts that secure the gearbox to the car body.
"Six" can look stylish
Steering was present in all cars: from the very first to the latest models, which not everyone can afford to buy. This part of the machine should not be changed, as safety depends on it. It is prohibited to make any changes to the control design. VAZ classics are popular - these are rear-wheel drive cars with a worm-type gearbox. But the steering column of the VAZ 2106 is different from the one installed on the 2107 model.
The latter is a little longer despite the fact that their scheme is almost the same. The VAZ 2107 model is equipped with a safety shaft, which folds in the event of a frontal collision and cannot injure the driver. The VAZ 2106 does not have such a system; the shaft is solid and does not contain hinges. There are also problems with the gearbox, which can be solved by simply adjusting the steering column. But the mechanism also has “incurable diseases”, in which it turns out to be easier to buy a new steering wheel and install it in place of the old one.
How to fix
What to do if the indicators are critical? Of course, eliminate the found play. The main reasons are in the steering column. She can betray her illnesses not only with deviations, but also with a corresponding knock. You will most likely notice the knocking only when the deviation is already large enough and adjustment is needed.
It is not possible to completely remove free play; remember the necessary margin to extend the service life of parts. We need to reduce it until we reach critical levels. Therefore, we climb into the area of the steering rack.
Task: tighten up all the parts and replace such consumables. Take a wrench or hexagon. We find the nuts that secure the spare part. It will be located next to the oil seals or other rubber elements. We need to adjust these nuts.
The process is not fast. We tighten it a little bit, and then take new measurements. And so on until we get to the right degrees. Additionally, you can replace the oil seals, lubricate everything that requires it, and check the fluids if we are talking about the hydraulic booster.
Often the driver is faced with such a malfunction as steering play. This problem can lead to serious problems, so it is important to detect and fix the problem in time.
The content of the article:
The steering is one of the most important for driving, and failure in the form of play is not one of the pleasant situations. Often the reason for the appearance can be various reasons, such as poor running gear, wear and tear of parts, and, most often, the condition of our roads. Therefore, we will consider how to identify play in the steering and how to carry out repairs.
Self-adjustment
You can tighten the steering rack on a Vesta yourself if you have the skill and experience in doing this work. The mechanism is located on the suspension subframe and is secured with two bolts. The casing protects the rail from mechanical damage and contamination. The reason for the appearance of extraneous knocks in the mechanism may be the loosening of the nut that tightens the sliding sleeve. The tightness of its fixation needs to be adjusted.
The steering rack on the Lada Vesta is tightened using a special octagonal wrench. For ease of operation, the machine is placed on a lift. Install the tool and begin to tighten the nut. The element is tightly fixed; a rotation of 40 degrees is enough for this.
The concept and causes of play in the steering mechanism
The steering design itself is not complicated. It contains a special rod that does not fit tightly to the car parts. It must have a small gap so that the parts do not wear out in case of friction. However, if the total play reaches fairly large levels, this can cause serious malfunctions, which can lead to accidents on the road. A backlash of 10° is considered an acceptable norm.
It is important to remember that a small play can develop into a large one, and therefore you should carefully consider this issue if there are clear signs of problems with the steering. These signs may include knocking, squeaking, vibration, or the need to turn the steering wheel hard to the left or right, even on a flat road. In this case, the steering wheel stops “obeying” the driver or performs actions somewhat late.
There are several reasons for the appearance of play and they all lie in the steering design itself. One of the first reasons may be that the tip or bearing has failed due to wear.
The second reason may be a recent car repair, namely the fact that sometimes the central hub nut is not sufficiently secured. This is where the backlash comes from. Also, free movement of the steering wheel may indicate that the hydraulic oil is becoming unusable and needs to be replaced.
In general, in order to discover the true cause of technical problems, the driver must check every detail of the entire steering system, since all parts and mechanisms are interconnected.
Device
The steering system on the VAZ 2107 is quite reliable. With its help, a sufficient level of controllability is achieved. Of course, the comfort of the car cannot be compared with modern models, but in general, this model is comfortable to drive.
Control is carried out by transmitting force from the steering column to the wheels. This happens through a gearbox with a worm gear. The steering column itself on the VAZ 2107 is composite. It consists of two parts connected by a universal joint. This allows it to fold up in the event of an accident, and leads to less injury.
The gearbox has an aluminum housing attached to the left side member (in some export versions to the right side). The body contains a globoidal worm. It is combined with a double-ridge roller. The gear ratio of this gearbox does not exceed 16.4. This allows the force to be transmitted as accurately as possible. The design also includes 2 ball bearings. They allow you to avoid increased wear of elements. Worm mechanisms are very sensitive to friction, so the gearbox contains gear lubricant. It must be checked regularly and added if necessary.
The steering mechanism also includes the following elements:
- Middle tie rod;
- Pendulum arm;
- 2 lateral (short) pulls.
The middle link is connected directly to the gearbox. This is a fairly reliable structural element. Failures of the long tie rod are rare. A pendulum lever is attached to it on the right. It ensures the stability of the entire system. Small tie rods have ball joints at the ends. This allows you to transfer force to the steering knuckle as efficiently as possible and without heavy loads. These levers are prefabricated. Thanks to the screw thread, it is possible to adjust the wheel alignment angles. The service life of these parts is from 10 to 15 thousand kilometers. When replacing, the new rods are made similar in length to the parts removed.
Conclusion
. The steering on the Zhiguli has its own characteristics. At the same time, such solutions are practically not used on modern cars. Therefore, the question of how to remove steering play on a VAZ 2107 is not uncommon. In general, fixing the problem is not difficult. But, in some cases, the adjustment does not help, then the gearbox will have to be replaced.
Welcome! Steering wheel play is a fairly common problem in almost all cars, especially cars of the “Classic” family. Backlash can occur for various reasons, ranging from a banal collision with a bump and ending with a malfunction in the steering system itself, so in order to remove the backlash you will have to make an effort that you will appreciate in the future.
Note! To adjust the backlash you will need to stock up on: A screwdriver and also a wrench set to “17”!

What can cause backlash? In fact, it occurs for various reasons, some of which were described above. But if play occurs, this may be to blame: A loose or heavily worn fastening of the steering mechanism, as well as the pendulum arm and the steering rods themselves.
Note! Before sinning on all these items of the steering mechanism, it is first recommended to check and, if possible, correct the increased gap that can be found in the engagement of the roller with the worm of the steering mechanism - we will do this adjustment!
How to determine the appearance of play in the steering
In order to check the car for problems with the steering, namely the presence of play, the following operations must be performed. First of all, it is necessary to switch the engine to a special operating mode when the vehicle is stationary - idle. After this, you should start turning the steering wheel and monitor the response time of the wheels to these commands. It is this distance that shows the amount of play.
Today, for the convenience and accuracy of measuring backlash, there is a special device - a backlash meter. It helps to measure and control the total backlash.
Eliminating play in the steering
First of all, the check should begin with the universal joint and its screws. Turn the adjusting screw to the required value. Afterwards, check again for the presence and amount of play. If the results are unsatisfactory, do the work again.
If this does not help, then the cause of the breakdown lies elsewhere. The next step is to drive the car into the inspection hole. The problem of play may lie in the steering rod joints. Most likely, these parts are worn out and there is a need to replace them or firmly fix them. You should also check the fastening of the steering rods and tighten them if necessary.
However, if this does not eliminate the cause, then most likely you will have to disassemble the entire steering system. It is better to do this at a car service center, as there is a risk of damaging the system.
Steering column
This is the shaft through which rotation is transmitted from the steering wheel to the gearbox. It is secured with a bracket to the car body.
A column is a shaft consisting of crosses. The design is very similar to a gimbal. In the event of an accident, the steering mechanism folds completely, which ensures the safety of the driver.
To facilitate control, the upper shaft rotates on two needle-type bearings. Repair of the VAZ-2107 steering control is necessary when the following symptoms are present:
- A creaking sound appears inside the column. The cause is usually deformation of the panel elements and steering column switch.
- An increase in steering play appears when the nut that secures the steering wheel to the shaft is loosened. To get rid of the damage, you need to tighten the nut by disassembling the steering wheel.
- The presence of play on the axle appears if the fastenings on the bracket and spline connections are severely worn out or weakened.
If the nuts and bolts become loose, the splines begin to wear away. In this case, the car can easily lose control. Be sure to correct the steering column play as soon as you discover a problem.
Cost of repairs to eliminate play in the steering
The price of a playmeter device is quite high and ranges from $400 to $800. Individual steering parts are represented by the following prices: bearing - from $12, nut retainer - from $16, steering rack rod - from $50, tie rod joint - from $16. At a car service center, repairs will cost around $20 or more, depending on the required service.
Video about steering play:
The importance of the steering system of a car is not worth mentioning once again, since it is already clear to everyone that it plays a key role in driving safety. That is why you should not neglect regular inspection and repair of all parts of this system, because frequent use leads to wear and tear of even the most reliable components and assemblies. The most common symptom of a malfunction is the phenomenon of steering wheel play. Any motorist who is more or less literate and knowledgeable about traffic rules should be familiar with this term in order to be able, if desired, to diagnose and fix the problem in a timely manner.
In order to understand how the total play in the steering works, you need to understand a little about the design of the steering system. From a technical point of view, it can be described something like this: in the transmission of steering rods there is a rod that is not fixed tightly, with a gap of 1-2 millimeters. If it were not for this distance, then all the parts involved would wear out much faster, as a result of strong friction. The gap allows you to hold the hook without coming into contact with the walls of the gear teeth - this is where the backlash arises.
From the driver's perspective, play is defined as the free movement of the steering wheel necessary to obtain the response of the element of the system that you control (in our case, the front wheels). Simply put, this is the distance that the steering wheel travels before the car makes a certain maneuver. This phenomenon cannot be called negative, since minimal play is present in the control of any car and increases in proportion to the size of the vehicle.
However, after a long period of operation, the backlash increases to a dangerous level, when the car stops listening and responds late to the driver’s “commands”.
If you do not react in time and do not carry out an inspection, at best you will face expensive repairs, at worst - according to the traffic rules, your car becomes a potential source of danger on the road.
Consequences
The car is an object of increased danger. If its control system is faulty, it becomes many times more dangerous.
Driving danger
It’s easy to imagine what will happen if the car’s chassis stops clearly responding to the driver’s actions. The sad consequences of this can affect not only himself and the passengers of the car, but also other road users, as well as pedestrians. In emergency situations, the driver simply will not be able to avoid danger, no matter how much driving experience he has behind him.
Responsibility for faulty steering
That is why all drivers must obey the immutable rule: if there is a malfunction in the vehicle control system, stop driving immediately . The same is officially required by traffic regulations. If the play in the vehicle's steering system exceeds the established standards, operation of this vehicle is prohibited. Ignoring this prohibition in accordance with Part 2 of Art. 12.5 of the Code of Administrative Offenses of the Russian Federation is fraught with penalties in the amount of 500 rubles. and a ban on operating the machine until the malfunction is eliminated.
The costs of towing the car to the impound lot and staying there, which accompany the ban on the operation of the car, fall on the shoulders of the careless driver.
The free movement of the steering wheel, which does not cause a change in the vehicle’s motion vector, instills anxious feelings in some drivers, while others simply do not pay attention to it. The first of them are wrong when the steering wheel play is permissible, while the second, when this value is exceeded, show criminal carelessness. In order not to go to extremes, it is enough to use a simple backlash meter to have an idea of the controllability of your car and drive calmly and safely.

Causes of backlash
You need to look for the cause of the play, of course, in the design of the steering system:
In general, backlash is almost always provoked by some kind of malfunction in the steering wheel-rack-traction-wheel chain.
In order to identify the cause, you need to go through each link, carefully check the details and identify where and what was not tightened - since it is precisely this element that is stopping the work of the control. But in order not to confuse the backlash with any other faults, you need to study its practical symptoms.
Principle of operation
To understand what steering play is, consider the principle of operation of steering systems in a modern car. The steering wheel is connected through a cardan joint to a mechanism that is a hollow (usually duralumin) tube, inside of which there is a gear rack moved by a gear connected to the cardan joint. The rack is connected through internal tips to rods, which are connected through external hinges to the steering arms on the front suspension struts. Thus, any movement of the rack leads to the rotation of the wheels and any play in the steering can lead to serious consequences from a delayed reaction to movement to a complete loss of control of the car.
How to remove
In order to adjust the steering, you will need a few simple tools that will allow you to adjust the mounts.
If the K 524 M play meter shows an undesirable result, you should try adjusting the universal joint reinforcement screws. These elements are located on the steering shaft. To do this, we find the hinge adjustment screw and set the acceptable value. Then the check is repeated, and if the free play is still exceeded, then the reason is different.
If the readings on the backlash meter are too high, it is also recommended to adjust the steering rod joints. But this will be more difficult to do, since you will need a lift or a room with an inspection hole. Most likely, you will find that the hinges are “broken,” which means their fastenings need tightening. You can also tighten the tie rods.
Sometimes the condition of the parts leaves no other options but to completely disassemble the steering mechanism and replace worn elements. In this case, it is better to turn to the services of a professional auto repair shop so as not to damage the system due to inexperience.
2.1. The total play in the steering exceeds the following values:
- Passenger cars and trucks and buses based on them - 10°
- Buses - 20°
- Trucks - 25°
2.2. There are movements of parts and assemblies not provided for by the design. Threaded connections are not tightened or secured in the correct manner. The steering column position locking device is inoperative.
2.3. The power steering or steering damper provided by the design is faulty or missing (for motorcycles).
Tie rod end and how to replace it.
When operating a vehicle, sooner or later there comes a time when it is time to replace the tie rod end. This article will actually be useful for anyone who decides to change a part on their own, without resorting to the help of a third-party technician
It is important to immediately note that the process of replacing spare parts for cars such as Dewoo Lanos, Dewoo Sense and Dewoo Nexia is not particularly difficult. Maintaining the original level of the tie rod and leaving the wheel toe in the same state is the only problem that a car enthusiast may encounter when replacing the tie rod end, himself
Even if something didn’t work out and the first pancake turned out to be lumpy, then by stopping at any car service station, the wheel alignment will be put in order instantly. So let's get started. Before you start work, be sure to check that you have the tools at hand:
- Ruler or caliper
- To remove the ball ends you will need a puller.
- You may need a pre-prepared metal tube 10-15 centimeters long and 12-15 mm in diameter.
- Keys size 12; 13; 17; 19
Now about the procedure for replacing the tie rod end on Dewoo Lanos, Dewoo Sense, Dewoo Nexia cars: When starting work, the car must be installed on a flat surface, secured using anti-underrun stops, setting it on the handbrake . After lifting the vehicle on a jack, remove the front wheel. For simplicity and convenience, you should turn the steering wheel to the left or right, depending on the side on which the part is being replaced.
Using a metal brush or other similar tool, clean the threads of the part from dirt. Unscrew the bolt at the terminal connection. Unscrew the nut on the ball pin of the tip. The finger should be pressed out using a puller. After this process is completed, using the tube, the tip should be unscrewed
It is important to note that when unscrewing a spare part, when working from the left side, the part should be unscrewed counterclockwise, and from the right side clockwise. Carefully count all the turns by unscrewing the tip
In order to ensure double control, we measure the distance from the fixed point on the tie rod to the fixed point of the tip using measuring tools. When screwing the end onto the tie rod, it is important that this is done the same number of turns as when removing it (checking can also be done using measuring tools). The bolt on the terminal connection must be firmly tightened. Next, on the steering tip, the ball pin fastening nut is also tightened. Put the front wheel in place.
The process is simple and not labor intensive. The most important thing is to understand the sequence of the process and you will succeed
It is important to note once again that if, after installing a new part, the car still drives, then the similar alignment has been lost and, but qualified specialists in a car repair shop can deal with this very quickly using special equipment.
