Front and rear suspension of the VAZ 2106: do-it-yourself chassis repair, installation of a double stabilizer

Method for checking the technical condition of the rear suspension

To check the serviceability of parts, the car is placed on an inspection hole or overpass. During a visual inspection, mechanical damage (cracking, ruptures, etc.) is unacceptable on rubber products. If the silent blocks of the rear suspension of the Zhiguli are a rubber mass squeezed out of the eyelets of the rods, they also need to be replaced. Be sure to inspect the attachment points of the rod brackets to the body for cracks. Defective areas must be welded.

To determine the condition of the rubber hinges of the longitudinal rods, put the car on the handbrake and rock the body in the longitudinal direction. Play in the connections will indicate worn bushings. The wear of the longitudinal thrust elements is checked by rocking the rear of the vehicle in the transverse direction. Repairing the rear suspension of a VAZ 2106 does not require special knowledge, but some metalworking skills are still needed.

Rear suspension upgrade

To do this, change the following spare parts:

• springs;
• silent blocks;
• shock absorbers;
• rubber bumpers.

Rear suspension of VAZ-2107

It is considered a classic to replace factory springs with those intended for the VAZ-2102(04) or VAZ Niva. These parts fit well into the circuitry here, but are also stiffer and more powerful. However, if the Niva’s springs are the same size as those of the VAZ-2107, then these spare parts from the VAZ-2102(04) lift the rear of the car, which is undesirable. In this case, to reduce the ground clearance, you have to do it yourself

remove one or two turns.

The front suspension of this model takes on the largest part of the mechanical load when driving. Therefore, owners of the VAZ-2107 model pay a lot of attention to it when repairing and tuning the car.

How a faulty suspension affects the movement of the car

The suspension may have several faults. Each of them influences the car’s behavior on the road in its own way.

• Rocking when braking and when starting - this is caused by faulty shock absorbers. Their job is to dampen spring vibrations. In addition, a non-working shock absorber leads to excessive roll of the car when entering a turn at speed.
• Knocks in the area of ​​the rear suspension of the VAZ 2106 indicate wear of the rubber inserts. If the sound occurs at the moment of starting and braking, then it may be the silent blocks of the longitudinal rods. Knocking on bumps indicates the need to replace the rubber bushings of the shock absorber mounts. The third type of knocking occurs when turning, when the rear of the car skids. This indicates the need to replace the longitudinal thrust bushings. Its function is to hold the rear axle in an exact position relative to the body. But the centrifugal force that occurs at the moment of skidding displaces the body relative to the bridge, which leads to knocking.

Diagnostics of the shock absorber condition

As for shock absorbers, there is nothing easier than checking them. Firstly, all their malfunctions can be felt while driving. If they do not work, then the absorption of road irregularities will be catastrophically weak. The shock absorber's job is to smooth out all the shocks that go to the car's suspension. When a wheel falls into a hole, the lower arm of the front suspension of the VAZ-2106 moves down, it is held in place by the pressure in the shock absorber.

Consequently, if the shock absorber is faulty, the suspension will move freely. Nothing will stop her from moving. Secondly, the presence of oil leaks on the shock absorber body should alert you. Even if just a little is squeezed out, where is the guarantee that the remains will not escape? In addition, the seal is clearly damaged. Press down on the car body, forcing it to the ground, and then quickly release it. Ideally, the body should make only one upward movement, no more!

If you urgently need a car, but yours is under repair, then you can always use the car rental service https://amigorent.ru/ and calmly resolve your affairs while your car is in the reliable hands of the masters.

Checking the condition of rubber parts

The next stage of diagnosis is checking the condition of the rubber bushings in the rods. To do this, you need to lift the car on a lift. Then a pry bar is inserted into the gap between the mounting bracket and the rod. You need to apply force and see how much the rod moves under the influence of force. Large play will be a sign of worn bushings and silent blocks. This procedure must be done sequentially with all rear suspension arms of the VAZ 2106.

A visual inspection of rubber parts can also tell a lot. Worn bushings often have cracks and are also crushed.

How is the repair carried out?

Do-it-yourself repair of a VAZ 2106 chassis can include a wide range of works, including:

1. Adjusting the bearings on the hubs.
2. Replacement of grease and bearing seals.
3. Replacement of front suspension shock absorbers.
4. Replacing springs in pairs.
5. Installing new joints on the upper and lower control arms.
6. Replacement of arms, both upper and lower.
7. Replacing anti-roll bar cushions on a VAZ 2106.
8. Installing new upper or lower supports.

After completing all of these or one of the listed works, it is necessary to have the wheel alignment done in a specialized workshop.

How to test the lower ball joint?

It turns out to be much easier to diagnose the condition of the lower ball joint. True, for this purpose you will need to use a caliper. However, if you don’t have one, then any thin metal rod will do. But if you plan to replace the front suspension of the VAZ-2106, stock up on all the necessary tools. If you can’t find any steel wire, then take a match. But you still need a ruler to take measurements. There is a very small plug bolt at the bottom of the ball joint.

Use a wrench or pliers to unscrew it. Now insert the caliper into the hole to check the distance between the top edge and the support pin. The maximum value of this distance should be 11.8 mm. And if you have even a little more, then the lower ball requires replacement. Of course, if repairs are being carried out, then it is better to change all the ball joints. Whatever one may say, this will have a real effect, even the steering play will decrease.

Front suspension VAZ-2106: device, features

The front suspension of the VAZ-2106 is of a double wishbone design. Since the car is rear-wheel drive, it works much more efficiently not with the classic McPherson, but with a double wishbone. The MacPherson type suspension has many disadvantages; they outweigh, and significantly, all the advantages of the system. Among the main advantages is that the manufacturing cost is much lower. But double wishbone suspensions have a huge advantage: they perform much better when traveling on rough roads.

Front suspension design

The front suspension of the VAZ-2106, the diagram of which is shown in the figure, is completely independent. The basis of the design is two levers located transversely. The front wheels are fastened using a bolted connection to the hubs. Inside the hub there is a tapered bearing, which is pressed in and secured with a nut. Please note that the nut with reverse thread is installed on the right side. If you are unsure whether you are installing the right nut, look at the edges. One of them should have three dots. We recommend: What is the fuel consumption of the VAZ 2114 per 100 km

Ball joints

The steering knuckle, to which the tie rod end is attached, is necessary to rotate the wheels. Using steering rods, the wheels are mechanically connected to the gearbox. The steering knuckle is attached at the bottom and top using ball joints. Moreover, their designs are different. The cups of both ball joints are mounted on the suspension arms.

The hinge pins are installed in the holes of the steering knuckle. The levers are fixed to the body using rubber-metal bushings, which are called silent blocks. It is with their help that the front suspension arms of the VAZ-2106 move relative to the body. The price of the lower one is 700-1000 rubles, the upper one - no more than 800 rubles. Ball joints cost 350-500 rubles. a piece.

Suspension check

It is imperative to diagnose the car’s suspension; to do this, install it on a lift or in an inspection hole. In this position, all suspension elements are much better visible. Very often the front suspension arms of the VAZ-2106 fail.

Despite the fact that their design is very reliable, cracks may appear, which will lead to the destruction of the front suspension. The procedures that need to be carried out on the car are as follows:

1. Wheel camber and toe adjustments are carried out every 10,000 km.
2. At similar intervals, you need to check the condition of your car tires.
3. Every 20,000 km, it is necessary to check the play of the front wheels and, if necessary, tighten the nuts on the wheel bearings.
4. Be sure to check the tightness of all threaded connections every 20,000 km.
5. Silent blocks, stabilizer pads, ball joints must also be inspected every 10-20 thousand km.

The most vulnerable point of the entire suspension is the ball joints. They are practically eternal, if only they are used under normal conditions. In other words, they should not be under heavy stress. And most importantly, the condition of the anthers must be ideal. Make sure that no dirt gets inside the hinges when operating. It is advisable to replace them at the slightest damage to the anthers.

Checking silent blocks

If the silent blocks on the car are worn out, then it will not be possible to set the normal toe-in and camber angles of the wheels. Therefore, it is necessary to repair the front suspension of the VAZ-2106; the price of a set of silent blocks is about 700 rubles. When the rubber part breaks, the lever moves. If there is even slight damage, it is advisable to immediately install new silent blocks. Moreover, you need to change everything at once, in this case the performance of the suspension will become much better and more efficient. And the levers will move normally relative to the body.

Before starting work, you need to place the car on a level surface and secure the rear wheels with wheel chocks. The side of the car on which the diagnosis is being carried out must be raised using a jack and the wheel removed. It is much better if all this work is carried out on an inspection hole or overpass.

You will need to measure how far the inner and outer washers move. The outer ones should move a maximum of 3-7.5 mm for the lower lever and 1.5-5 mm for the upper one. The displacement of the internal washers should not exceed 2.5 mm on both arms. It is quite possible that the radial displacement of the silent blocks in the levers will be too large. In this case, only installing new elements will help.

Diagnostics of the upper ball joint

To carry out the work you need to use help. Place an assistant in the car, behind the driver's seat, so that he squeezes the brake. Only in this case will you eliminate the possibility that during diagnostics you will be able to feel the wheel bearing being displaced.

Use sharp movements to rock the front wheel. If suddenly there is even the slightest play in the ball joint, you will definitely feel it. When pushing back and forth, the wheel will move freely. It is possible that there will be a creaking or crunching noise coming from the upper ball joint.

Diagnostics of the lower ball joint

On the lower arm of the front suspension of the VAZ-2106 there is a ball joint, which is secured with three bolted connections. It is much easier to check the condition of the lower ball joint than the upper one. To work you need a caliper. But if you don’t have it, then a match, a thin needle, stiff wire and a ruler will do. Pay attention to the bottom of the hinge, there is a small plug in it.

It can be unscrewed using a wrench or pliers. You need to install a caliper in the hole. The distance from the edge of the ball joint housing to the steel pin should not exceed 11.8 mm. And if you take measurements using the same match, then you need to install it in the hole, mark the location of the edge of the edge and take the measurement with a simple ruler. If only the lower ball joints on the car are faulty, the best repair option is to replace these joints all around.

How to check shock absorbers?

If the shock absorbers are damaged, this can be felt when driving. All road surface irregularities are absorbed very poorly, as a result of which the suspension does not work properly. After falling into a hole or hitting a bump, a car begins to sway for a very long time. The shock absorber is attached to the car body and to the lower suspension arm. If it is faulty, the lower arm will not encounter resistance and will begin to move freely. Another sign that the shock absorber has become unusable is the appearance of a leak on its body.

If the seals are damaged, oil comes out. In this case, the operation of the shock absorber strut is disrupted. To assess the condition of the shock absorbers, you need to sharply press on the side of the car body to bring it as close to the ground as possible. Then quickly release. With fully functional shock absorbers, the body will make no more than one upward movement. Otherwise, partial repair or replacement of the front suspension of the VAZ-2106 will be required.

How to replace shock absorbers and springs?

If one shock absorber fails, it must be replaced in pairs. If the shock absorber on the left front side has become unusable, then the right one is changed along with it. Only in this case will the normal operation of the entire suspension be ensured. Similar requirements apply to springs.

If these suspension elements wear unevenly, the car may simply become uncontrollable when cornering. When replacing front shock absorbers, you can use a small hole, but it is better to do everything on a lift or overpass. Sequencing:

1. Using a 17 mm wrench, unscrew the nut in the engine compartment that secures the shock absorber rod.
2. Remove all rubber cushions attached to the rod.
3. Push the shock absorber rod until it fits into the body as far as possible.
4. Unscrew the two nuts from the lower arm that secure the shock absorber housing.
5. Pull the entire shock absorber down.

We recommend: How to recognize a good car service?

If the work takes place on a flat surface, then you can dig a small hole under the lower arm, 15-20 cm is enough. The main thing is that the shock absorber can be removed. Or you can drive your front wheel onto a small hill, for example, several blocks of wood.

How to adjust the front bearings?

Very often the front bearings on the front suspension of a car break. It is advisable to inspect them every 10,000 km. Diagnostics and configuration are as follows:

1. Use a jack to hang the wheel.
2. Remove the dust cap.
3. Unlock the nut on the hub.
4. Using a 27 wrench, you need to tighten or unscrew the nut.

Please note that you should not use too much force when tightening. Once you have tightened the hub nut all the way, you need to turn it back 60 degrees and fix it by knocking off the edge of the nut with a hammer. The bearings have a cone shape, so if the permissible tightening torque is exceeded, they are destroyed. But they can easily withstand heavy loads, since the rollers and the holder have a very large contact area.

What does the front suspension consist of?

It’s worth starting with the fact that the front suspension of the VAZ-2106 is completely independent. It is based on two wishbones. The front wheels are attached to the hub using bolts. The latter is mounted on bearings. They have a conical shape, are pressed into the surface of the inner hub and are secured with a nut. It is worth noting that the right wheel uses a left-hand threaded nut. To distinguish it, just look at the edges - three dots are marked on them.

The next element that makes up the front suspension on the VAZ-2106 is the steering knuckle. A steering tip is installed in it, which is connected to the gearbox. It is used to turn the wheels. This fist has two attachment points to the suspension - top and bottom. It is made using movable ball joints, the cups of which are attached to the levers, and the pins are pressed into the holes of the steering knuckle. The levers are fastened using silent blocks - specially shaped rubber-metal bushings - to the car body.

Do-it-yourself replacement of VAZ-2106 silent blocks video instructions

Silent blocks are used in the construction of cars of all models. They are rubber inserts between suspension parts; they are used to absorb vibration and, accordingly, to prolong the uninterrupted operation of the machine’s chassis. The silent blocks themselves are subjected to very high loads, which leads to their frequent failure.

In this article we will talk in detail about how to replace silent blocks on a VAZ-2106 car, we will provide step-by-step instructions and useful recommendations, thanks to which you can perform this rather complex procedure with your own hands, without involving car service specialists.

Tools and accessories needed to replace silent blocks

First of all, you will need to prepare all the necessary tools. Without them, it will be quite difficult to get to the silent blocks in a VAZ-2106 car and dismantle failed parts. So, for high-quality and convenient repairs you will need:

• special tools for dismantling ball joints, the upper arm, removing and installing a new hinge made of metal and rubber, as well as for unpressing the far steering tips;
• open-end, ring and miter wrenches for 13, 22 and 24 millimeters;
• jack;
• set of mounts;
• a thin and sharp chisel that will allow you to carefully dismantle the lower silent blocks without removing the lever;
• hammer.

Additionally, you will need to prepare the new suspension components that will be installed on the vehicle. Today it is best to buy polyurethane silent blocks, which differ from ordinary ones in their service life increased several times.

But if your goal is to carry out repairs at minimal cost, then you can get by with traditional rubber parts.

Step-by-step instructions for replacing upper control arm silent blocks

If the entire tool is already ready for use, we begin to replace the rubber-metal hinges, which is performed according to the following scheme:

• jack up the car and remove the wheel from the side on which the work will be done;
• unscrew the nuts holding the silent block and the steering tip;
• Unscrew the fastening nut of the ball joint;
• using a special puller, press out the bipod support pin;
• remove the nut holding the upper arm;
• we take out the lever, carefully clamp it in a vice and change the silent blocks using a special device;
• We install the lever in the reverse order. After this, all that remains is to mount the wheel and remove the jack. The same work is performed on the other side.

It is much easier to replace the silent blocks of the lower arm:

• after removing the nut holding the lever itself, we take a special device and press out the rubber-metal hinge;
• We carry out preparatory work. During this process, it is necessary to remove dirt and carefully lubricate the seat for the new silent block, as well as the lever axis and threads. This, firstly, will greatly facilitate subsequent procedures, and secondly, it will ensure stronger fixation of the part;
• press in a new silent block;
• install the steering ends and insert the cotter pins that secure these parts;
• tighten the nuts of the upper and lower arm.

The procedure for replacing silent blocks must be carried out under load. It is best to first seat your acquaintances or friends in the car, and also place a load weighing 40 or more kilograms in the trunk.

The nuts of the upper and lower arms must be tightened until they stop only after the new silent blocks have been installed. Otherwise, serious problems with the operation of the car suspension may arise.

Removing the lower arm

When a VAZ 2106 chassis is being repaired, it may be necessary to replace the lower front suspension arm. To work, you will need wrenches 13 and 22. First, remove the front suspension spring, and then, using a wrench, unscrew the two nuts that hold the arm to the cross member. Remove it from the cross member bolts without removing the silent blocks, axle and ball joint. If necessary, replace the ball joint or change the lever. Reinstall it in the reverse order of disassembly.

Replacing ball joints

Sometimes self-repair of a VAZ 2106 chassis requires replacement of ball joints. First you need to diagnose the element as follows:

• hang the wheel;
• place something under the lower arm;
• lower the car.

When lowered onto the stand, the lower arm will stop putting pressure on the suspension. Grab the wheel with both hands from below and above, and make several sharp movements: the top towards you, and the bottom away from you, and then vice versa. If at the same time you hear a knock and feel play in the hub and caliper in the area of ​​the ball joints, the front suspension of the VAZ 2106 requires repair.

To replace, you will need a jack, a hammer and a regular set of wrenches. First you need to dismantle the wheel and unload the suspension, and then use a 22mm wrench to unscrew the nut of the lower or upper support. Give a few blows with a hammer to the protrusion of the steering knuckle, releasing the ball joint, and then release the support from the lever.

Using a 13mm wrench, unscrew the 3 nuts on the bolts securing the ball to the lever. When removing the ball from the lever, be careful. It is better to dismantle the plate along with it, not forgetting to put it in place when installing the ball joint. Don't forget that the lower and upper supports are different from each other. Assembly is carried out in the reverse order of disassembly.

Modernization of VAZ 2106 suspension

Today, many owners of classic Zhiguli cars are improving their cars and making changes not only to the appearance, interior, power unit, but also to the suspension. VAZ 2106 is a car with a wide field of activity for tuning. The only limitation is the financial capabilities of the owner. Let's look at the main points for modifying the suspension.

Air suspension

One of the options for modernizing the suspension is installing air struts. After implementing such a design, it becomes possible to change the ground clearance and generally increase the level of comfort. The car receives driving characteristics similar to the behavior of imported cars. When installing air suspension, both the front and rear shock absorption systems are subject to conversion. To do this, purchase a kit of necessary items, which includes:

• compressor;
• connecting elements;
• pneumatic struts;
• sensors, etc.

to pneumatic changes in this order:

1. Remove the springs from the suspension.
2. We cut off the bumper almost completely and make a hole for mounting the air strut in the lower cup and upper cup.

Reinforced springs

They resort to installing reinforced springs on the “six” when it is necessary to make the suspension stiffer, since many are not satisfied with its softness.

Equipping a car with hard spring elements will lead to the fact that when making a sharp turn, there is a possibility that the wheels on the other side will come off, i.e., traction with the road will deteriorate.

Springs from a VAZ 2121 along with a reinforced cushion are often installed on the front of the car. Such elastic elements have a slightly larger coil thickness and rigidity. The rear suspension is mainly equipped with springs from the “four”. In addition to them, dampers from Niva are installed, which will be especially important for those cars that run on gas, since the equipment weighs a lot.

Electromagnetic suspension

Another option for improving a car’s suspension is electromagnetic suspension. The basis of this design is an electric motor. It can operate in damping and elastic element mode. The operation is controlled by a microprocessor. This type of suspension is installed instead of standard shock absorbers. The uniqueness of the design lies in its virtually trouble-free operation. Plus, it has a high level of security. If for some reason the pendant loses power, the system can switch to mechanical mode thanks to the electromagnets. The most popular manufacturers of such suspensions are Delphi, SKF, Bose.

The suspension of the VAZ “six” does not stand out for its complexity. Therefore, the owners of this car can repair it. You can identify and fix problems by reading the step-by-step instructions. When the first signs of problems appear, you should not delay repairs, since other suspension elements will also be subject to increased wear.

Adjusting the front bearings

This procedure should be carried out as often as possible - approximately every 10 thousand km. mileage On a VAZ-2106 car, the front suspension needs constant monitoring; unfortunately, this is the most vulnerable unit. You hang the wheel, remove the protective cap, after which you will need to loosen the nut on the hub. And only after this you need to use a 27 wrench to unscrew or screw in the nut. It depends on which direction the adjustment is required.

Note: the tightening force should be light. In addition, after tightening, it is necessary to make approximately a sixth to seventh part of a turn in the opposite direction. The fact is that the hub has cone bearings, which are easily destroyed when trying to tighten it with force. But they are able to withstand heavy loads due to the fact that the contact area between the holder and the rollers is rather large.
