oil in the steering gearbox of a vaz 2107 what kind of oil to pour

The steering mechanism of a car consists of a steering wheel, a shaft, a gearbox, rods, a trapezoid, a pendulum and steering knuckles.

Due to the steering gear, which transmits forces from the steering wheel to the rods, the front wheels of the car rotate at a given angle.

Transmission oil poured into the steering system helps ensure stable operation of the gearbox and reduce wear on its parts. If it leaks, which occurs regardless of the condition of the gearbox, and untimely replacement occurs, the problem of dry friction in the unit arises. As a result, the quality of driving deteriorates, the rotation of the steering wheel becomes difficult, and its play increases.

Let's take a closer look at what oil is used for the VAZ 2107 steering gear, how to check its level and replace it.

everything useful is here

Using the “8” wrench, unscrew the filler plug in the steering gear housing. Fill the transmission oil to the bottom edge of the hole.

Checking the steering condition

We check the steering together with an assistant on a lift or inspection ditch.

We install the wheels in a position corresponding to the linear movement of the car. Apply a mark to the steering wheel rim with chalk.

We check the free play (play) of the steering wheel by turning it in both directions before the car wheels begin to turn. The free play of the steering wheel should not exceed 5° (or 18–20 mm along the wheel rim).

The steering wheel turning force should not exceed 20 kgf when installing the front wheels of the car on a smooth slab (linoleum).

When quickly turning the steering wheel left and right, with amplitudes of about 10°, we check by touch that there are no knocks (plays) in the joints and ball joints of the steering. We tighten the loose threaded connections.

We check the absence of axial and radial play in the pendulum arm,...

...check for any play in the ball joints of the rods. We check the movement of the rod ends along the axes of the hinge pins,...

...applying axial force to the ends of the rods. Axial movement should be within 1–1.5 mm. After removing the force, the tip should return to its place. If there is no axial movement or the tip does not return to its place, replace the tip or steering rod assembly with serviceable ones.

Changing the oil in the steering gear on a VAZ 2101-VAZ 2107

The control gearbox of this unit has a huge number of names, some call it “Steering Column”, some “Steering Mechanism”, and some “ Steering”

gearbox." In fact, of all these listed titles, the most reliable is only “Steering mechanism” since this particular title was given to this unit during the creation of cars of the “Classic” family.

But not all car enthusiasts know why a car needs this part in the first place, so now we will briefly tell you about it and show you an annotation on changing the oil in the steering gear, which is located a little lower.

To change the oil you will need: A clean rag or, instead of it, it is best to use an iron brush in order to clean the dirt from the gearbox housing cover!

In addition to these devices, you also need to stock up on: A screwdriver, as well as a main set of wrenches, a “12” hexagon and a regular or oil syringe for pouring oil into the gearbox!

Briefly about the steering gear:

This is the most basic component of the control frame, since thanks to this unit, when you turn the steering wheel, the wheels of the car also turn, in other words, it transfers the force when turning the steering wheel to the wheels, thereby steering the car.

When should you change the steering gear oil?

What kind of oil is in the VAZ 2107 steering gear

The problem of steering wheel play in classic cars is not new; every owner has encountered it, and while in the city it is still possible to drive with play, on the highway you get tired of constantly catching the car and any trip over any serious distance is very tiring. Solving this problem is very simple. : just tighten the adjusting bolt. We also have 0.18 liters of oil poured into the steering mechanism. I think few owners of classics changed the oil there (actually, I never thought about it either), and yet the oil change interval set by the manufacturer is 60,000 km. The steering mechanism is not demanding on the quality of the oil, the main thing is that it just needs to be there. Therefore, I did not buy expensive oil, but bought 1 liter of Lukoil TM-5 80w90 mineral oil for 150 rubles.

I also bought a “measuring” cup, a 20ml syringe and a drip set.

We will need a tube from the dropper since we do not have a drain plug, but only a filler plug, which performs both functions.

Changing the oil in the steering gear of a VAZ 2106

Because any VAZ steering mechanism leaks, over time a layer of dirt accumulates on it, it must be cleaned off so that it does not get into the oil. This is what it looks like

We unscrew the plug with a key of 8, insert the tube from the dropper inside and suck out the old oil with a syringe, if it is still there, I had about 40 ml out of 180. After this, you can fill in new oil, at a level of about 15 ml below the filler hole, after that we tighten traffic jam

After the work done, I felt like I was driving a different car, the steering wheel began to turn easier and the play disappeared almost completely, I regret that I didn’t do this 3 years ago. I recommend it to all owners of classics.

How I changed the oil in the VAZ steering gear! Steering gearbox VAZ 2106

The design and principle of operation of the VAZ 2106 steering mechanism

The design of the VAZ 2106 steering mechanism is very complex. However, it is precisely this that allows the driver to confidently control the car in a variety of situations. All elements of the control system are shown in the figure below.

The control system of the “six” is very complex and consists of many elements

Here it should be said about the ease of control of the “six”. To turn the steering wheel, the driver makes a minimum of effort. And therefore, less tired on long trips. The steering of the “six” also has one more feature: play. It is very minor and is not a sign of a problem with the steering system. Play in the “six” steering wheel is a common occurrence; it occurs due to the abundance of various rods and small elements in the control system. Finally, in the latest models of the “sixes” they began to install injury-proof steering columns, which could fold in the event of a strong impact, increasing the driver’s chances of surviving a serious accident. The VAZ 2106 steering mechanism works as follows:

How to change the oil in the steering gearbox, also known as the steering mechanism, on a VAZ 2101-VAZ 2107?

Before you start replacing, check the oil level in the system and be sure to look where the steering mechanism is located and how to understand when it’s time to change the oil! (For answers to all these questions, see the article: “Checking the oil level in the steering

columns")

READ Is it possible to mix automatic transmission oil from different manufacturers?

1) First, check that the car’s engine is warmed up to operating temperature, and if necessary, then get into the car and warm it up so that the engine is warmed up to its operating temperature.

Changing the oil in the VAZ 2106 steering gear

In this video I will tell you how to change the oil in the control gearbox.

This is necessary so that the old oil drains faster from the steering gear housing, and also so that dirty oil residues also come off the cylinder walls. Also, keep in mind that when the engine is warm, the oil will be hot, so be careful and don’t hurt your hands!

2) Now completely unscrew the upper bolt of the oil filler neck, and into the hole that will appear after the bolt is unscrewed, you will need to insert a syringe specially designed for filling oil and with its power, collect all the oil that will be inside the gearbox, as shown in the small photo.

3) When the oil is collected using a syringe and poured into a container, check its condition. Foreign bodies such as small metal particles, etc. should not be found in the oil, so if unwanted parts are noticed, then you will need to flush the gearbox from them, but the gearbox

flushing is not so easy, firstly, you will need a special supercharger with a dispenser (working on the principle of excess pressure) with which you can direct the oil in the gearbox from bottom to top, but this supercharger is mainly only available in car service centers, so flushing We recommend that you produce the gearbox there.

It is recommended that it is best to fill the steering mechanism with TAD 17 transmission oil, but if the car is operated at sub-zero temperatures, then you will have to refuse to fill such oil, because it freezes at sub-zero temperatures!

Filling the oil back is very simple; through the filler hole, using the same syringe, new oil is poured into the gearbox crankcase, that’s basically all, and when the oil

If it is filled, tighten the top filler plug and you can assume that the oil in your steering gear has been changed.

Before tightening the oil filler plug, wipe it completely free of dirt with a clean rag!

There is an interesting way by which you can change the oil in the steering gear, it is described in the video located just below, check it out and decide whether you need to change the oil in the steering gear or not.

HOW TO REMOVE THE GEARBOX

To dismantle the steering column on the “seven”, you will need the following tools:

• a set of keys;
• knob;
• heads;
• steering rod puller.

After preparing everything you need, perform the following step-by-step actions:

• The car is placed on a lift or inspection hole.
• Clean the steering rod fingers from dirt.
• The rods are disconnected from the gearbox bipod, for which the cotter pins are removed, the nuts are unscrewed and the pin is squeezed out of the steering gear bipod using a puller.

• The gearbox is fastened to the body with three bolts. Unscrew the 3 fastening nuts, remove the fasteners and dismantle the steering mechanism from the car. To make it easier to remove the assembly, it is better to turn the bipod all the way into the column body.

ADJUSTING THE STEERING COLUMN

Adjustment work on the steering gearbox on a VAZ 2107 is resorted to when the steering wheel becomes difficult to rotate, jamming occurs during rotation, or when the steering shaft moves along the axis with the wheels straight.

To adjust the steering

speakers, you will need an assistant, as well as a 19-mm wrench and a flat-head screwdriver. The procedure is carried out in the following sequence:

• The machine is installed on a flat horizontal surface with the front wheels located in a straight line.
• Open the hood and clean the steering gear
  from contamination. The adjustment screw is located on top of the crankcase cover and is protected by a plastic plug, which is pryed off with a screwdriver and removed.

• The assistant begins to intensively rotate the steering wheel to the right and left, and the second person uses the adjusting screw to achieve the desired position in the mesh of the gears. In this case, the steering wheel should rotate easily and have minimal free play.

When the adjustment is completed, hold the screw with a screwdriver and tighten the nut.

GEAR OIL

To reduce friction of internal steering

columns, transmission oil GL-4, GL-5 with viscosity class SAE75W90, SAE80W90 or SAE85W90 is poured into the mechanism. In the old fashioned way, many car owners use TAD-17 oil for the unit in question. The filling volume of the gearbox on the VAZ 2107 is 0.215 liters.

Signs of breakdown of the gearbox and other elements of the steering system

The steering gearbox on a VAZ 2106 very rarely fails alone. As a rule, a gearbox failure is preceded by the failure of several elements of the steering system, after which the gearbox itself breaks down. That is why it is better to consider the problems of this system as a whole. We list the most well-known signs of a breakdown of the control system on the “six”:

Now let’s look at what exactly can cause the above symptoms and how to eliminate them.

Steering system noise

Here are the main causes of noise behind the steering column:

Leakage of lubricant from the gearbox

A lubricant leak indicates a violation of the seal of the device.

Oil leaks are clearly visible on the steering gear housing

Here's how it happens:

The steering wheel turns hard

If the driver feels that it has become very difficult to turn the steering wheel, this can happen for the following reasons:

STEERING COLUMN REPAIR

Due to constant friction in the steering mechanism, elements wear out, which indicates the need not only for adjustment of the unit, but also for possible repairs.

Work order

Unscrewing the plug for filling oil into the rear axle gearbox of a VAZ 2107

• Place a container under the drain hole to collect used oil.
• Use a hex wrench to “12” to unscrew the drain plug to remove the used oil.
• After the liquid has completely drained, the drain plug is screwed into place.

Advice: If the oil drained from the gearbox housing has a dark color or metal particles, the rear axle gearbox must be washed.

• To flush, you need to fill in about one liter of a mixture of thirty percent kerosene with gear oil. Instead of kerosene, you can use diesel fuel.
• One rear wheel is lifted, first gear is engaged and the engine is started.
• After three minutes, the washing mixture is drained.
• For filling, it is better to use an oil blower or a lever grease gun. If you don’t have them on hand, you can use a large plastic syringe with an elastic tube attached to its end.
• 1.3 liters of special transmission oil is poured into the gearbox.
• It is necessary to ensure that its level reaches the lower edge of the filler hole.

After filling the oil, the breather is checked and cleaned of dirt. This device is necessary in order to relieve excess pressure in the gearbox that is formed when the oil heats up and when its level rises. All operations for changing the oil on a VAZ 2107 car can be clearly seen in the video.

Features of lubricant selection

In the rear axle gearbox of a VAZ car 2107

It is recommended to fill in semi-synthetic gear oil. It should have viscosity parameters 75W-90. This is Niva’s version of lubricant, which is usually poured into the gearbox.

READ How many liters of oil in Hyundai Solaris automatic transmission

Special gear oil in the gearbox improves the quality of parts and also reduces their wear. Not every G7 owner knows how much oil needs to be poured into the gearbox. The lubricant volume for the gearbox is 1.35 liters. It is poured through a special filler hole (on the side), using a technical syringe. You must first drain the old lubricating fluid, for which there is a special drain plug at the bottom.

Steering of a VAZ 2107 car

On the VAZ 2107 model, the steering has a safety design with an articulated-lever steering wheel drive and a worm-roller gearbox.

• The steering gearbox is secured with three bolts in the engine compartment on the left side member.
• An adjusting screw installed on the top cover of the gear housing can be used to adjust the gap in the engagement of the double-ridge roller and the worm built into the structure of the device.
• Approximately 0.2 liters of oil is poured into the steering gear housing.
• To fill the oil, there is a filling hole on the top cover of the gearbox housing. There is no hole for draining the oil; fluid is only added to the VAZ 2107 if necessary.

Filling oil in the steering gearbox

Before adding oil, check the oil level:

• The vacuum booster is removed.
• Using a key set to “8”, unscrew the plug for filling oil into the gearbox, which has a conical thread.

Unscrewed plug from the filler hole of the steering gearbox

• A special rod is used to check the oil level. To do this, the rod is inserted all the way into the gearbox, as shown in the photo .

• From the top edge of the filling hole, the oil level should be at a depth of 15 millimeters.
• If you need to change the oil in the steering gear of a VAZ 2107, then use a spanner wrench to “13” to remove the four bolts that secure the lower cover of the gearbox.
• Just slide the lid and pour the oil into the container.
• The cover is put in place, secured with bolts and new oil is poured.
• The plug is screwed into the filler hole.

Timely oil changes in the main components of the VAZ 2107 will increase its service life without costly repairs. And the price for oil changes is acceptable for all car owners.

Which oil is better to choose for the VAZ 2107?

Thanks to driving a car, you accumulate a certain mileage. As soon as the vehicle's mileage reaches 60 thousand km, an experienced driver knows that it is time to change the lubricant. When changing the oil, attention should be paid to the correct choice of lubricant.

Before you start changing the oil in the gearbox, you need to know the principle of operation of transmission fluid. When choosing a lubricant for a mechanism, the following factors should be considered:

• Product compatibility. When adding new fluid without flushing the crankcase, the remaining mixture should mix without negative consequences.
• Compatible with mechanism materials. Non-ferrous metals are not recommended for Litol, which contains alkali.

The manufacturer recommends pouring oil into the gearbox

for VAZ 2107 the following viscosity classes:

• SAE75W90;
• SAE75W85;
• SAE80W85.

For the VAZ 2107, it is recommended to use lubricant of group GL-4 or GL-5. The first type of lubricant contains a high concentration of additives, and the second type of fluid, GL-5, is used to lubricate rubbing gears. For the gearbox, the correct choice would be to select a mixture of the GL-5 group.

Why do you change the oil?

The rear axle gearbox is a mechanism that is subjected to a number of different loads. Through these loads, destructive actions occur. To avoid accelerated wear of gearbox parts, it is necessary to use a special lubricant. This lubricant is an oil that, during the operation of the gears of the mechanism, envelops them, eliminating accelerated wear and overheating, and also cleans the teeth from chips and metal dust.

It is necessary to change the oil in the rear axle gearbox for the simple reason that over time it loses its primary properties. When the gears rub against each other, thermal energy is released, the value of which is reduced with the help of a lubricating fluid. In addition, when the gears rub, the teeth wear out, resulting in the formation of chips and metal dust. If you do not change the lubricant in the gearbox for a long time, the amount of metal shavings and dust will only increase, which will lead to accelerated wear of the rubbing parts.

When to change gear lubricant

Changing the oil in the rear axle of a VAZ 2107 should be done regularly, but there is no specific threshold. It all depends on many different factors, but the manufacturer of a domestic car recommends performing this procedure every 60 thousand km.

Some of the main factors that influence the timing of oil changes are:

1. Driving character. Frequent and abrupt starts are not at all beneficial to the parts and mechanisms of the car, including the rear axle.
2. Vehicle operating conditions. If the car is used in rural areas where there are poorly paved roads, dust, and dirt, then replacement should be done more often.
3. Lubrication quality. It is recommended to fill the rear axle of the VAZ 2107 with special high-quality oil. If you pour low-quality lubricants into the gearbox, you will need to replace them much more often.
4. Operating a vehicle with a trailer. The wear of the device parts will accelerate if the car is operated with a trailer in which cargo is transported.

Determining the oil level in the gearbox

If we talk about the volume of liquid poured into the gearbox, it is 1.35 liters. The algorithm for replacing the oil composition in the rear axle is in many ways similar to the algorithm for replacing the oil composition of the gearbox.

It is recommended to change the oil fluid before operating the vehicle in both the winter and summer seasons. By the way, the viscosity of the composition is different for these periods: in winter the consistency is more liquid, in summer it is more viscous.

Before replacing the oil composition in the rear axle of a VAZ, you can determine the fluid level in the gearbox. To do this, you will need a container with a volume of slightly more than 1.5 liters.

The next stages of work look like this:

• First of all, you need to put the car on the inspection hole;
• Next, you should clean the dirt from the drain and filler plugs;
• Using a 17 mm socket wrench, you need to unscrew the plug covering the filler hole;
• Next, you should check the oil fluid level using a suitable tool, for example, a screwdriver - the fluid level should reach the very bottom of the filler hole;
• If the oil fluid level does not reach the lower edge, you need to add transmission fluid using a special syringe, and then tighten the hole well using a plug.

How to change: main stages of the process

Successful replacement of the transmission fluid in the gearbox occurs after a trip of more than 5 km. This is necessary for the liquid to warm up. Change the transmission oil by immovably fixing the car on an overpass or inspection hole. Operations are performed according to the following instructions:

• use a 17 key to unscrew the filler hole plug;
• Use a 12mm hex to unscrew the drain plug;
• drain the waste liquid (remember safety precautions - the substance may be hot);
• clean plugs and holes from contamination;
• tighten the drain plug;
• using an oil pump or its equivalent, you need to fill in the required volume of new fluid (as a rule, pour until the lubricant begins to pour out of the filler hole);
• tighten the plug that closes the filler hole.

Since the same oil must be poured into the gearbox and rear axle gearbox, it is better to change it in these units at the same time. 3 liters will be enough (1.3 liters fits in the gearbox).

How much oil is poured into the VAZ 2107 axle?

Many VAZ 2107 car owners are interested in the question: how much oil should be poured into the main components of the car, such as the engine, gearbox or rear axle? In fact, this information is included in every vehicle operating manual that is issued upon purchase at a car dealership. But if you are the owner of a used vehicle or for some other reason do not know what the main filling capacities of important units are, then this information will be provided in more detail below.

Oil level in the rear axle gearbox.

check and add oil

to the level in the crankcase, rear axle gearbox, advice in the process. VK Group.

By the way, when installing a new gearbox, if you have changed it, then after filling the oil, we recommend driving it for almost 50-100 km, and then pouring the oil into a clean container and letting it cook for a month or two. (it should be noted that the dirt settles completely transforms), after which it can be filtered and reused, and it is necessary to drain the oil after such a small amount of time, since inside the new gearbox there will be dust and dirt on its walls, and you remove all that gunk with a quick oil change!

How to change the rear axle oil on a VAZ 2101-VAZ 2107?

1) First oil you need to heat the heated oil

, it flows faster and all the dirty particles inside the gear housing flake off and mix with the oil, so you pour out all the oil and all the dirt that is on the walls of the gear housing (there is oil in the gear housing), to heat the oil, start the engine next to machine and let it run for a while as the engine temperature gauge shows the operating temperature, finish warming up and turn off the engine near the machine. machine, at this moment the oil transmission is heated to the highest temperature. Uri (about 75-90 degrees) so be careful while pouring so that it doesn't burn.

2) Stock up on a steel brush, wipe the filler cap off it and drain the dirt from it, you won’t be able to do this, but if you have a brush at hand, still follow the advice after this operation, turn to strain. and when you feel that the plug is already there, it will be unscrewed, put the hex key aside and with your hand unscrew the plug as shown in the photo below, please note that after removing the plug from the hole in which it is closed, the oil will spill, so Prepare an empty tray immediately.

If you want to carefully pour all the oil and all the dirt out of the transmission and then slightly lift the right rear of the car with a jack, the car will fall to the left (towards the car) and all the oil

It would be better to drain from the gearbox, because there are drainage holes not directly at the bottom, but a little to the side (you can see this in the small photo below)!

3) Wait for the oil to drain and wipe the drain plug dry (from the inside, wipe the most important thing inside, you can't wipe it properly from the outside), wrap it in place, and then pay attention to the drained oil from the gearbox. there should be no obvious iron filings (if there is something very bad, in which case change your own driving style, because the gears in the gearbox cannot withstand such loads and crumble a little or just change the oil in time) silver dust is noticeable, but it also not very thin, but more than iron filings are clearly visible, and if there is oil in your coffee, it may mean that the gearbox on your car is not tight and water is getting into it, mixing with the oil and giving the color of the coffee (this color It can also be in cars that have been sitting in an unheated garage all winter or just for a long time. In this case, there is condensation inside the gearbox, which turns into water, mixing with the oil in the whole thing), well, the most common color. just black, oil

can be replaced with this color if you put it in a dirty gearbox (it just takes time from the gearbox, time to wash off all the dirt, see how to do this in the article: “Washing rear axle gearboxes on VAZ cars”), and Over time, the oil can turn black when it has lost all its additives and can no longer protect and lubricate the transmission.

Let's add a little to the article, there is a fan on the gearbox (marked with an arrow), it should move easily and without any foreign interference, so turn it the same way and press it, by the way, if it does not work, then the oil through the seals can easily start squeeze when the gearbox warms up (the higher the temperature of the gearbox, the greater the pressure inside it), in detail Read about this fan in the article: “Replacing the cuff of the transmission behind the axle on a car! "

avtoexperts.ru

In the article “Power steering oil: choosing the right one,” we talked in detail about the composition and function of hydraulic fluids for power steering. This material contains details about how long the working fluid lasts and how to replace it correctly.

When to change power steering oil

Some car dealers claim that the hydraulic fluid poured into the power steering from the factory cannot be replaced throughout the entire life of the vehicle (this mainly applies to the so-called “green” oils). This statement is wrong. Hydraulic fluid is a consumable material that is subject to such concepts as aging during operation. You need to understand that there are recommended (planned) periods for replacing power steering fluid by the car manufacturer (noted in the operating manual), and there are special replacement periods - early and emergency.

It is recommended to change the working fluid in the power steering once every 1-2 years, depending on the make and model of the car, as well as on its operating conditions. The more severe these conditions, the shorter the period of scheduled oil change in the power steering.

The hydraulic fluid in the power steering is changed ahead of schedule due to failure of the steering mechanism elements (racks, pinions, rods). In order for the newly installed steering elements to work smoothly, it is recommended to replace the power steering fluid - especially if it has been used without replacement for several years.

Emergency replacement of hydraulic fluid in the power steering is carried out in the event of depressurization of the hydraulic booster system or failure of its components and mechanisms (hydraulic cylinder, control spool, pump, hoses).

It is necessary to periodically, once every six months, check the level and condition of the hydraulic fluid in the expansion tank.

Oil level in the power steering reservoir

If the level has dropped (and it should be in the tank between the Min and Max marks), then the system may have depressurized and the oil is leaking. Then it is necessary to check the condition of all components of the power steering system, identify the breakdown and correct it. If this is not done in time, the consequences can be dire: increased wear of the working parts of the pump (as a result - failure of the steering mechanism housing in the area of ​​the compression rings), decreased mobility of the pump pressure reducing valve due to insufficient heat removal from the pump components, increased wear of the teeth of the steering rack and gearbox shafts.

How does power steering work?

We simply check the condition of the working fluid in the power steering: open the expansion tank, use a dipstick to take a certain amount of oil and apply it to a clean sheet of paper. If the liquid is transparent and has a stable color, everything is fine with it. If it is cloudy, with visible impurities, the oil needs to be replaced. The appearance of sediment in the hydraulic fluid indicates that its additives no longer cope with their functions due to decomposition during operation. If such a fluid is not replaced, the oil in the power steering may foam, oxidize, lose its lubricating and anti-corrosion properties, which will lead to system failure.

Replacing power steering fluid: five simple steps

To replace the working fluid in the power steering we will need: a jack, a medical syringe, a clean rag, a canister of power steering oil. On average, no more than 1 liter of liquid is taken for replacement. The recommended amount can be found in the vehicle's owner's manual.

Step 1.

We place the car on the lift. If it is not there, then we use two jacks to hang the front wheels.

Raise the front wheels using a jack

Step 2.

Open the cover of the power steering expansion tank and use a medical syringe to pump out the waste fluid.

Pumping out the old fluid from the power steering

The remaining liquid in the tank can be drained by removing the hoses in sequence (the main one leading to the pump and the return one coming from it) and lowering them into a prepared container (a plastic 1.5 liter bottle will do). First, remove the main hose (usually located below), turn the steering wheel to bleed the system.

Drain off the remaining liquid. Using the example of Hyundai Accent

We do not turn on the engine! When the liquid has stopped dripping, install the main hose in place, remove the return one and perform the same actions with it.

Step 3.

Pour fresh hydraulic fluid into the power steering expansion tank, monitoring its level. The optimal level is between the Min and Max marks. Note that some expansion tanks have four marks: Min Cold and MinHot, Max Cold and Max Hot. Cold is the level of “cold” fluid, Hot is “hot”, that is, when the car is in use.

Fill with fresh liquid

Step 4.

Rotate the steering wheel left and right to pump fluid through the power steering system. Again, mark the oil level using the marks - if it becomes less, top it up, and so on until we have established the optimal level. Screw on the expansion tank cap.

Step 5.

We lower the car from the lift and remove the jacks. We start the engine, drive a few kilometers and again measure the fluid level in the power steering reservoir. If it is in the middle of the Min Hot and Max Hot marks, then you no longer need to add oil. If the fluid exceeds the Max Hot level, then you need to drain a certain amount of fluid, since during operation (when heated), it can splash out of the tank and flood nearby engine components, which will lead to engine failure.

As you can see, there is no particular difficulty in the process of replacing the working fluid in the power steering. However, it is important to remember that changing the oil in the power steering should be done carefully, using clean materials at hand, since dirt getting into the fluid can lead to a deterioration in its performance. For those who are not confident in their own abilities, we advise you to change the power steering fluid at a service station - there this operation is carried out on a special stand, which guarantees a high-quality oil change.

Which lubricant to choose

Many drivers have a reasonable question: what kind of oil to fill? Oil

Mechanics recommend filling the rear axle gearbox of a VAZ-2107 with a viscosity of 75W90, 80W90 or another suitable one with API classification GL-4/GL-5.
For example, Castrol 75W90, Lukoil 80W90. In winter, it is better to fill the rear axle of the VAZ- 2107
with synthetics. In summer, mineral water.

How much to fill (volume)

You won’t believe it, but there are also owners who don’t even know that the rear axle of a car also needs regular lubrication, although not as often as the engine. Also, there are drivers who believe that if the oil does not expel or ooze, there is no need to change it at all. This is all wrong and it is also necessary to perform this procedure, as in the internal combustion engine and in the gearbox.

The lubricant volume should be 1.3 liters. To fill the required level, you need to wait until the oil flows from the filler hole; this will be considered the optimal volume.

Checking the oil level

Control checks of the fluid volume in the gearbox should be carried out every 10 thousand kilometers, as well as when malfunctions or visual leaks occur. Checking the oil level in the rear axle is quite simple. To do this, you will need a container with a volume of about one and a half liters, a 17mm wrench and a screwdriver. The next steps are:

• the car is placed on a viewing hole, overpass or lift;
• the filler plug is cleaned of dirt;
• use a 17 key to unscrew the filler plug;
• The oil level is controlled with a screwdriver: the liquid should reach the edge of the hole.

If there is insufficient protective liquid, it is necessary to add it using a syringe or other device.

How much oil is required

Before proceeding directly to the procedure, you should decide how much oil to fill. According to the manual, the volume of oil required in the drive axle gearbox of the “classic” is 1.35 liters. Therefore, when preparing for the procedure for changing it, it is recommended to prepare a larger amount - approximately 1.5 liters of liquid. The remaining volume is needed for internal cleaning of the gearbox: the mixture with diesel fuel is poured.

Replacement

The oil is changed according to the same algorithm as the oil in the gearbox, after a mileage, so that the oil is hot and drains better:

Changing the oil in the steering gearbox on a VAZ 2107-2101

— place a container for used oil under the drain hole

- after the oil has completely drained, tighten the drain plug

- pour oil into the filler hole until oil flows out of it

Differences between oil changes in other VAZ models

If extraneous sounds and knocks appear that are felt through the steering wheel, on a VAZ 2106, changing the oil in the steering gear is a mandatory and urgent process. Having installed the machine in the inspection hole, the first step is to check the lubricant level in the gearbox.

The difference between the change is that the gearbox on the VAZ 21213 does not have a drain plug, like on the VAZ 2107 and 2106. To change the oil in the VAZ 21213 steering gear with a volume of 0.2 liters, you need to prepare two syringes. The liquid is sucked out through one syringe, and filled in using the second.

When replacement may be needed

The lubricant loses its properties over time. The oil in the bridge must be changed regularly, according to the instructions. But during operation, signs of malfunctions may appear, which indicate the need for a faster change of waste fluid:

• whistling and noise appear from the side of the bridge;
• when the nature of the load changes, knocking noises become audible;
• There are drips and traces of oil fluid on the gearbox.

The car care instructions state that in the VAZ-2107 the rear axle oil is changed for the first time after running in (2000 km). And then it needs to be changed every 60 thousand kilometers. But, given the difficult climatic conditions with ultra-low temperatures, bad roads and constant driving in city traffic jams, it is recommended to fill in new oil after 30 - 35 thousand kilometers. Unscheduled maintenance when purchasing a used car, major repairs are also accompanied by the replacement of lubricant.

Experts advise changing the lubricant in different seasons (winter and summer). In winter, the oil composition should be more liquid, with a lower pour point. And in summer it is more viscous.

Oil change instructions

You can replace the gearbox lubricant in an inspection pit, overpass or lift. Before driving the car into the pit, you should drive a little and warm up the axle fluid. You should also prepare in advance a tool (a set of keys and screwdrivers), containers for working, protective gloves, rags, a special syringe or a device with a hose for pouring.

Changing the oil in the rear axle gearbox of the VAZ-2107 is performed in the following order:

• Clean the drain and filler plugs from any dirt.
• Using a 12mm wrench, unscrew the drain plug.
• Drain the old gear oil into the prepared container. Remember that the liquid will be hot after warming up.
• Tighten the drain plug.
• Unscrew the filler plug.
• Pour in enough oil to reach the bottom edge of the hole.
• Tighten the filler plug. Make sure there are no leaks.

If inspection of the used fluid shows severe contamination, then you need to rinse the gearbox before filling in a new one. To do this, mix transmission or motor oil with diesel fuel in a ratio of three to one. The resulting mixture is poured into the reducer. One wheel is lifted with a jack. The engine starts and first gear is engaged. This process takes several minutes. After this, the cleaning fluid can be drained and new drive axle grease can be added.

Oil for the rear axle gearbox of VAZ 2107

Oil in the gearbox - all the mechanisms that rotate and rub against each other need oil, the same with the gearbox, inside it there are gears (They are metal) that rub against each other during operation and if they are not lubricated with anything, they will quickly come out (They will become scuffed or even deformed and the gearbox will have to be replaced), and when lubricated they will rotate and rub against each other with much less friction and therefore the wear of the parts will be reduced (They will not fail so quickly) , in addition, the gears in the gearbox will also work more quietly and thus it will not hum and vibrate too much as it will if you completely drain the oil and start the car.
