Rear suspension on the VAZ 2107 - design and repair

The need for such an event as replacing the rear springs of the VAZ 2106 is caused by their wear or destruction. Wear is expressed in the subsidence of the car during operation; destruction occurs with constant overload or driving on country roads. Some car enthusiasts remove springs in order to change worn rubber spacers, which can also cause the car body to settle.

Replacing the VAZ 06 springs can be done on an open, flat area, having good anti-recoil means, since the car will have to be raised and lowered several times. The process itself is simple; almost every VAZ 2106 owner can do it. To do this you will need:

• jack and wheel wrench;
• wheel chocks or comfortable stones;
• a set of spanners or open-end wrenches;
• 2 spring ties;
• low wooden block or cinder block;
• powerful flat screwdriver;
• hammer;
• fabric gloves.

During such repairs, cloth gloves are worn to avoid injuring your hands during the work on the protruding parts of the suspension and car body. Spring ties can be found from one of your car enthusiast friends; many VAZ 2106 drivers have this device in their arsenal. As a last resort, it can be purchased at an automotive supply store. Replacing springs also involves replacing rubber spacers, which serve as a gasket between the upper coil of the product and the glass in the car body.

Do-it-yourself replacement of VAZ 2107 springs

The suspension design of the domestic VAZ 2107 car has springs, the main purpose of which is to ensure a smooth ride. Many owners install longer springs than standard in order to raise the car body. Over time, they sag, which makes it impossible to compensate for the load. Weak springs reduce ride comfort, worsen vehicle handling and lead to rapid wear of suspension elements. To prevent this from happening, they must be checked and changed in a timely manner. Let’s find out in more detail what it is to replace VAZ 2107 springs.

You can change the rear springs yourself even in the absence of an inspection hole (only a jack is sufficient). You can find out the dimensions of the socket heads and spanners required to unscrew the upper or lower shock absorber mountings in the repair and operating manual for your car model. In some cases, having two jacks will make the process much easier.

Replacing rear suspension springs will be much easier if you use special ties. For example, on a VAZ 2101, 2102, 2106, 2107, you can remove the old spring and install a new one using conventional installation, but the design of the rear suspension of many other cars will not allow such a trick. We will show you how to change rear springs without zip ties, but we recommend using this method only if absolutely necessary. The price of screeds is not so high as to sacrifice your own safety.

DIY Replacement Guide

We will demonstrate the replacement procedure using the example of a VAZ 2101-2107. After reading the instructions, you can easily carry out this procedure on another car, since the basic provisions apply to all types of rear suspension.

1. Loosen the wheel bolts.

Raise and secure the rear part of the car on the supports. Be sure to install the wheel chocks diagonally (if the rear right side is raised, the chocks are installed under the front left wheel).

2. Unscrew the lower shock absorber mounting. If for any reason problems arise with the bottom bracket, you can unscrew the top mount. The shock absorber will limit the travel of the beam (on cars with rear-wheel drive and all-wheel drive - the rear axle), so we need to disconnect one of its fasteners from the car body.
3. Using a pry bar, pry the lower end of the spring by the coil to release it from the mounting groove. There is no need for such manipulations if the spring is slightly tightened with ties.

When tightening, be sure to ensure that the coils are tightly secured by the claws of the ties. If the spring jumps out, it can cause serious injury!

How to properly install new springs

On many cars, there are special grooves in the upper and lower cups for fixing the outer turns. During installation, it is important not only to clean the seats from dirt, but also to ensure that the outer turns are positioned correctly.

Just on the VAZ 2101-2107, the upper rubber spacer, like the metal ring, have a special groove. In order not to guess the location of the spacer, before installation, secure it with adhesive tape to the upper turn, and then install it in its assembled place. During the operation of the car, the rubber damper often sticks to the body, so to remove it you will need a large impact screwdriver or a crowbar. We recommend watching the video, which clearly shows the process of self-replacement.

Springs must be changed in pairs - on both sides of the axle at once.

Beam with silent blocks

This type of beam is installed on Daewoo Lanos, Opel Astra F, Vectra A and many other foreign cars. In order not to tear the silent blocks, it is advisable to unscrew their fastenings. If defects in rubber products are detected, we recommend replacing the silent blocks of the rear beam at the same time. Please note that replacement must be done one at a time, since the beam is attached to the body only with silent block fastenings and shock absorbers.

As practice shows, the rear springs can be changed without unscrewing the silent blocks. To increase the beam travel, it is enough to jack up the lower part of the beam on the opposite side. To do this, lift the body with a jack and secure it on the supports. Remove the wheels, then place the jack as close to the end of the beam as possible. Raising in this place will provoke lowering of the beam on the replacement side.

Rear suspension device of VAZ 2107

The rear suspension, according to the website mashinaa.ru, is dependent, since the car has rear-wheel drive with a rigid axle. The bridge is fastened to the body using special torque rods, which are attached to both sides of the bridge. The rods are made in the form of pipes, at the ends of which there are ring fastenings. On the axle of the car and under the bottom of the body there are exactly the same fastenings, with which the jet rods are engaged.

The traction ring is installed flush with the ring on the body and a bushing with a rubber ring, called a silent block, is threaded through the aligned holes. Such rubber products provide a soft connection between the suspension parts and ensure their unhindered movement relative to the road surface.

At the ends of the bridge, special cups are installed in the upper part, on which suspension springs are placed. The springs are made in the form of spirals with a round cross-section and rest against the car body through spacers. The spacer is an aluminum ring that rests against the body; a rubber lining is installed in the ring itself to soften the impact of the spring on the body.

When hitting an obstacle, the springs create an oscillation that counteracts the force of the impact and softens it. To quickly dampen vibrations in the VAZ 2107 suspension, oil shock absorbers are used. The shock absorber consists of a container filled with oil with two chambers and a piston with a check valve system. When vibrations occur, the shock absorber is set in motion and moves a special fluid inside the chambers, which provides resistance to the shock absorbers and, in turn, reduces these vibrations.

1 — suspension spring; 2 — screw of the device; 3 - support plate.

• Insert screw 2 of tool 67.7828.9504 into the hole in the upper support of the suspension spring.
• Then place the support plate 3 on the spring coil 1 and on the screw 2 from below and secure it to the spring with a clamp.
• Screw the nut onto the screw from below so that the nut retainer fits into the socket of plate 3.
• By turning screw 2 with a wrench, compress the suspension spring until the suspension arms are completely unloaded.
• Take out the axis of the upper arm and disconnect it from the body.
• Disconnect the lower control arm axle from the cross member and remove the suspension assembly from the vehicle.
• Remove the spring, smoothly unloading it, remove the device and repeat the operations for the other suspension unit.
• Remove the engine splash guard and stabilizer bar.

NOTE! When removing suspension components, it is necessary to note the number and location of the adjusting washers between the axis of the lower arm and the cross member, as well as the adjusting plates between the cross member and the body side members, so that when installing the units, put these washers and plates in their original place.

Replacing the front springs of a VAZ 2107:

1. Remove the front wheel and unscrew the stabilizer from the front lower arm and the shock absorber.

In order to remove the front springs on a VAZ 2107, use a puller consisting of two jaws; it must be installed between the coils of the spring.

3. Now you need to press the lower ball joint pin out of the steering knuckle and move the hub mounted on the upper ball joint to the side.

4. Loosen the nuts of the lower arm using a 22mm wrench.

5. Push down the lower arm and pull out the spring along with the puller from the lower arm.

6. Replace the insulating gasket.

7. Install the new front springs of the VAZ 2107 in the reverse order, remember that they must be tightened with a puller.

8. Before tightening the lower arm axle nuts, place the machine on its wheels.

At this point, the replacement of the front springs of the VAZ 2107 is completed and your car is ready for use again.

When it's time to replace

There are several signs by which you can determine that it is time to replace the springs. These signs are:

• Detection of damage and defects in the product design. This malfunction can be determined by visual inspection, but first you need to put the VAZ 2107 car on an overpass.

Their significant subsidence. If the vehicle's ground clearance decreases significantly, this indicates sagging of the devices in question. Springs quickly sag in such cases when the car is used to transport heavy loads every day. Also, those cars that are used as taxis also require frequent replacement of the devices in question.

If you find a problem with the springs on a VAZ 2107, then you should replace them without delay. This will extend the life of other suspension elements and save money. It is recommended to replace devices in pairs, since replacing only one element will cause the body to skew, which will negatively affect driving. In some cases, spacers help when the springs have sagged but are not deformed. Experts believe that you should not get carried away with spacers, since the physical properties of a car with spacers are many times worse. As a result of such modifications, the suspension does not function correctly, which affects many factors: from control to comfort. Therefore, if necessary, it is better to replace the springs, both rear and front. We will learn how this is done on a VAZ 2107 from this material.

Selection of springs for foreign cars

Springs for foreign cars have progressive and linear characteristics:

• Linear spring characteristics mean that the springs do not change their properties as the load on them increases. The stiffness of such springs does not change, no matter how loaded they are. Therefore, when choosing which springs are softer, you should pay attention to this.
• Progressive characteristics, on the contrary, change the properties of the springs depending on the increase in load. The greater the load on such a spring, the more its rigidity will increase.
• There are four types of springs, the most common are standard ones; they usually replace the original car springs after they are worn out or broken.
• There are also reinforced springs; they are installed on cars in which the load on the rear of the car periodically increases. Usually these are cars with a trailer.
• There are also variable-load springs that have variable pitch; they are installed to increase ride comfort and work only when the load increases.
• The last type of springs are backlash or sports. They are installed in order to lift the car a certain distance.
• When buying springs, you should only contact specialized auto parts stores. Only there you can purchase spring models that can be used successfully for a long time. The leading companies producing springs are: Killen, Suplex, K+F, LEJOFORS. You should replace springs with new ones only after the car has been in an accident or after damage to the front and rear axles of the car.

For a more complete understanding of the factors for choosing and installing springs, you should refer to special sites, for example, here or here.

Today you can find several varieties of such parts. They can be like this:

• Standard types, intended for use in urban environments;
• Reinforced parts. For production, rods with an increased diameter are used. Designed for vehicles that are designed to transport large loads, when compared with conventional vehicles;
• Raised parts are used when it is necessary to slightly increase the vehicle's ground clearance;
• Lowered products are used to reduce ground clearance, this can increase the dynamic performance of the car;
• Variable stiffness of parts is used to ensure a smooth ride and comfort in all road conditions.

Replacing Front Springs on a VAZ 2107

replacing a VAZ 2107 spring

[important] Suspension springs on the VAZ 2107 are the main element of the suspension, ensuring a smooth ride. Free (suspension) springs are not able to compensate for the load, which leads to suspension failure. the rear axle or front control arms were struggling with the rubber shock absorbers on the body. This reduces comfort, affects handling and stability, and leads to premature wear or damage to the suspension and body parts. ago, the springs on the VAZ2107 and periodically change them if necessary. [/ important]

VAZ owners often strengthen conventional springs or install ready-made springs with greater stiffness to improve handling or comfort on a busy road.

When to change springs

Two main signs that you need to replace your VAZ 2107 with a spring::

1. Damage appeared on the sources. This can be determined by visual inspection.
2. The springs sag a lot. This is marked by a decrease in the Seven's ground clearance, especially under load, and frequent suspension breakdowns when driving on bad roads.

In both cases a replacement must be made. Sometimes VAZ owners try to restore the stiffness of sagging springs using spacers. This solution is not entirely correct. The dynamic properties of the working spring and the spacer spring are different, so the suspension will not work properly. In addition, cracks may appear on the reinforced spring.

Replacement of front springs from VAZ 2107

To work you need:

• a set of keys;
• jack (screw or hydraulic);
• ball wrench;
• metal brush;
• hammer;
• mounting oars;
• insulating tape;
• wire hook.

Replacing VAZ 2107 front springs is as follows:

• lift the car and remove the wheels;
• remove the shock absorber;

Replacing rear springs

Replacing a VAZ 2107 with rear springs is much easier than with front springs. To do this you will need:

The replacement procedure is as follows:

• unscrew the pressure regulator rod in the rear brake circuit;
• unscrew the rear pipe tee;
• unscrew the lower shock absorber mount;
• lift the car and release the shock absorber and spring;
• remove the spring with gaskets;
• check the condition of the gaskets, replace if necessary;
• install the spring with spacers and reassemble the suspension parts in the reverse order.

To ensure proper comfort, you need to choose the right features of these products. Incorrectly selected parts deny all the positive qualities that can be obtained from its installation. Springs and their stiffness depend on the following parameters:

• The diameter of the spring plays a big role. The larger the diameter, the higher its rigidity;
• An increase in its outer diameter leads to a decrease in the stiffness index;
• Increasing the number of turns leads to a decrease in stiffness;
• Formation also plays an important role in determining the characteristics of products.

Seven is very customizable, relatively cheap, simple and fun. Even the most minimal changes can make a car much better and more attractive than a factory-produced car. One of these changes is the replacement of parts in the rear suspension.

Many owners try to install stiffer parts in the suspension. Let's try to find out what this gives to the car and the owner. This change significantly increases the steering wheel's sensitivity to driver input. Aerodynamics become such that with a sharp turn, the wheels on the opposite side of the roll can even come off the road, which significantly impairs their grip on the road surface.

The most common springs in the rear suspension are springs from the VAZ 2104. Such a replacement may not be acceptable in all cases. Experts recommend such a replacement for cars that convert to using gas fuel, especially methane. Cylinders for this fuel have a significant weight, so installing such parts will be very useful. For such products, it is recommended to install Niva shock absorbers, the travel of which is more than standard.

Fans of sporty style install products with reduced rigidity. They have green marks. I want to warn you that driving a car with such parts along country roads will add problems to the owners. Many drivers deal with them very radically. They cut off exactly one turn on reinforced products. You have to be very careful with this as if you cut a little more the pieces might just fall out of place.

I want to warn you that you need to change products in pairs, that is, both parts are changed on the same axis. What sources to put on the VAZ 2107 instead of “sifting” is up to you to decide, but the approach to this issue is balanced enough to eliminate the occurrence of unnecessary problems.

On sale are reinforced springs and spacers. what to prefer? VAZ-2101. 2107.

It's no secret that Zhiguli sedans, from VAZ-2101 to 2107, have a common weakness - rear suspension springs. Probably chosen for “comfort” reasons, they work acceptably when the machine is not very loaded. And under full (albeit within normal) load, they are compressed so much that on an uneven road the rear axle beam can hit the bump stops. This can also be caused by problems with the shock absorbers, especially if the car is far from new. Over time, due to changes in the structure of the metal, the stiffness of the springs also decreases - they sag, the compression stroke becomes very small, and under heavy loads almost disappears. In general, as a movie character would say, with such springs there is no life!

Placing spacers under the springs will not really solve the problem. Firstly, metal fatigue takes its toll - and one day the spring simply breaks. Secondly, frequently repeated impacts destroy the bump stops; in addition, cracks appear in body parts, especially if the spring is compressed before the coils collide. That is why the installation of rubber spacer rings, although it increases cross-country ability, is still rather self-deception.

There are also rubber inserts on sale that are designed to be installed between the coils of a weakened spring. Their main drawback is the same as that of spacers; Let's add fragility to this.

Meanwhile, springs from the VAZ-2104 station wagon are allowed to be installed on the Zhiguli sedan. These springs are 21 mm longer - hence the additional load capacity.

There is another option - however, which did not receive the go-ahead from VAZ - replacing the standard rear springs with rear springs from Niva.

The table shows the basic data of various springs.
