As many car owners know, silent blocks have a direct impact on wheel alignment angles. Therefore, a beginner needs to understand how important it is to monitor the condition of these elements. Replacing the silent blocks of the front levers of a VAZ 2110 is quite simple, but today we will reveal some of the repair features to you.

When replacement is required

It will not be difficult for a more or less experienced driver to understand that the silent blocks are out of order and they need to be replaced. First of all, you will feel a certain discomfort while driving, you will hear the impact of iron in the suspension. But that's not all.

If you do not replace the front silent blocks on a VAZ 2110 in time, the fasteners and connecting elements will be destroyed, play will appear, and the wheel alignment angles will change. This does not entail anything good.

Determining the need to replace silent blocks is not difficult if you pay attention to the characteristic signs of their wear:

• While driving, strong or minor rubber squeaks are observed. It all depends on the degree of wear. Loud noise is a very bad sign;
• A noise similar to a knock is heard in the wheel area. This indicates that the silent blocks are poorly fixed and they are gradually destroyed;
• Cracks form on the surface of the elements, after which the process of disintegration of the silent block begins. In such a situation, it will be impossible not to hear a knock.

Signs of wear

During operation, silent compounds are exposed to reagents used on winter roads, dirt and large temperature changes.
The rubber-metal hinge loses its elasticity over time, cracks and wears out. Theoretically, the resource of silent blocks is 100,000 kilometers. However, they have to be changed (they cannot be repaired) much more often, every 50,000 kilometers.

Some of the signs that silent blocks need to be replaced are:

• the appearance of extraneous creaks and knocks in the area of ​​the vehicle’s chassis;
• play of levers and wheels;
• uneven tire wear;
• loss of stability of the car on the road, difficulties in controlling it (the car seems to become “wobbly”);
• Upon visual inspection of silent blocks cleared of dirt, cracks and damage to the rubber are detected.

An indirect sign is considered to be a violation of the camber/toe of the car's wheels, if it is known that it was previously adjusted.

Replacement of silent blocks of front levers of VAZ 2110

Some car owners are afraid to replace the silent blocks of the front beam on a VAZ 2110 on their own. But in vain. Contacting a service station entails serious financial costs. Plus, it’s far from a fact that the service station will do your job better than you would have done yourself.

Press-fitting

The only thing is that you may need the help of a car service friend. All service stations have a special puller in their tool arsenal. There is no point in purchasing it, since it is expensive and is rarely needed by a car owner. Some craftsmen even make their own puller using a homemade method. There are many drawings and diagrams according to which it is made. So you can try it if you have free time.

The design of the puller is quite simple - the puller legs are about 20 centimeters long, a pair of washers and two tubes.

There are two silent blocks in the front beam - in the front upper and front lower arm . The procedure for replacing them is somewhat different from each other, so we will consider the processes separately.

Front upper control arm silent block

Broken

Let us immediately note that it is easier to work with it than with the second element. The entire procedure involves performing several sequential operations.

1. Raise the car on a jack and secure it in a stationary position. Turn on the handbrake, put stoppers under the wheels.
2. Remove the front wheel.
3. Unscrew and remove the support. To do this, you will need to turn the wheel out and hit the bipod with a hammer. It is better to do this through some kind of insert.
4. By knocking out the support, you can remove the upper front control arm without serious problems.
5. There is a bolt on the side, it is quite long. Unscrew it. Inspect the end play. Most likely, it is quite serious and is easily felt when checking. Therefore, you absolutely correctly decided to change the silent blocks.
6. You can remove the silent block with a hammer and chisel. Just don't hit it too hard, or you'll damage other suspension components.
7. In some cases, the silent block sits very firmly, so you can’t do without a drill and drilling it. After making the holes, you can safely remove the element.
8. Now use the smaller bushing to press the new silent block into place. The part must fit firmly and securely into the socket.

about axial play . To eliminate it, you can go in two ways:

• The first is to replace the entire pole. The option is so-so, since its cost is very high, but the quality is quite low;
• The second is to tighten a couple of washers from the sides. They will not allow the mounting bolt to dangle.

The disadvantage of the second option is that installing washers sometimes leads to a situation where the silent block does not fit on the lever. Therefore, you have to reduce it with a hacksaw. Unfortunately, this leads to a reduction in the service life of the silent block.

Preparation for work on replacing silent blocks

To press in new silent blocks you will need a special puller.

Before you begin the process of replacing suspension parts with your own hands, you need to prepare a place and a set of tools. A garage with a spacious inspection pit is ideal as a place. As for tools, to replace you will need:

1. Set of wrenches and sockets with ratchet.
2. Special puller for pressing out silent blocks. You can either buy this specific tool or ask your garage mechanic friends to borrow it while you work.
3. VD-40 or analogues.
4. Soap solution.

The necessary puller is quite easy to make from a pipe of a suitable size, a long bolt and a washer.

If you cannot get a puller, you can use available equipment. This can be done by a tube of suitable diameter with washers and a vice.

Replacement process

If replacing rubber suspension parts is new to the car owner, it may immediately seem like a very time-consuming and complicated procedure. Often, at the inspection stage, inexperienced VAZ-2110 owners decide that they won’t be able to do anything on their own. In fact, the replacement process is quite simple. If you do this once, changing any silent blocks in the future will be easy and simple.

The only problem may be pressing the new silent block into place, since the new parts may be poorly processed or too rigid. This is especially true for parts made of polyurethane.

Selection of parts and necessary tools

Before you start directly replacing silent blocks, it is important to properly prepare for it. There are few specific recommendations for choosing new parts. The auto parts market is simply filled with silent blocks from different manufacturers, mostly they are all quite good. The only thing you can do to make a better choice of new parts is to consult with auto mechanics in your area. The main thing is that the new vibration isolators fit completely.

For repair work you will need the following things:

Set of new silent blocks

Unscrew the nut of the stabilizer bar mounting bolt.

Unscrew the nut on the extension

Unscrew the nut of the bolt securing the lever to the body

A long bolt, a couple of washers and a nut are all sold in hardware stores and can be used to make a puller

“Let’s spritz”, it’s better to heat it up some more. Next, we use our puller to press out the silent block.

We clean the socket from rust and dirt, lubricate

We press new silent blocks into the mounting groove

New silent block installed

Important! Many car enthusiasts do not press out silent blocks, but burn them out, which is extremely wrong. During heat treatment, the quality of the metal from which the lever is made seriously changes for the worse.

Replacing silent blocks in the rear beam

Replacing the rear silent blocks is done as follows:

1. Again, the car must be driven into a viewing hole or raised on a lift.
2. Then, taking a 19mm wrench, you need to disconnect the rear beam from the bracket by unscrewing the nuts securing it.

Important! After carrying out measures to replace silent blocks (both front and rear), it is very important to do a wheel alignment.

Removing the upper arm structure

To remove and replace the silent block of the upper front arm, it will take less effort and time than with the second part. Sequence of work:

1. The vehicle must be raised using a jack and secured securely. Next you need to tighten the handbrake;

3. dismantling the upper front arm;
4. on the left side of the structure you need to unscrew the long bolt. The presence of axial play indicates that the silent block requires replacement;
5. at the next stage you need to knock out the silent block using a chisel and hammer. The work must be done carefully so as not to damage other suspension parts;
6. it is possible that the motorist will not be able to remove the silent block without using a drill. After drilling, the part can be removed quite easily; then you need to install a new part on the seats. For pressing, it is recommended to use a bushing with a smaller diameter.
