Correct replacement of silent blocks

Translated from English, the word "silentblock" (silent) means "quiet." Based on this, you can immediately understand that this part will perform the function of damping the sound. To be more precise, the silentblock is designed to reduce or prevent the occurrence of all kinds of noise and vibrations in the suspension of the car. So, let's take a closer look at this part and figure out how to replace the silentblocks.

What is this detail?

Silentblock consists of a metal hinge, most of which is covered with rubber material. As a rule, this insert is installed between two bushings (this is the steel hinge). It is this spare part that fixes all the parts and assemblies that are in the suspension of the vehicle. Timely replacement of silent blocks of the rear beam ensures effective damping of various impacts and vibrations that occur when a car hits a pit or other irregularity.

What signals a breakdown?

In the event that this part has come into malfunction, the driver feels a significant change in the behavior of the machine, its handling and so on. Also, when you hit obstacles, the suspension of the vehicle reacts very badly, there is a sharp screeching and squealing when driving. All this indicates that the machine requires an urgent replacement of silent blocks. Otherwise, after several hundred kilometers of operation, the driver will feel uneven wear of the tread of the tires, which may entail even a major overhaul of the suspension. Therefore, you should not postpone the replacement for later, because in spite of the fact that this is a rather primitive detail, it performs rather serious functions.

Replacement of Silentblocks VAZ: short instruction

So, let's look at the main stages of replacing this part by the example of the cars of the Volga Automobile Plant.

The whole process begins with the preparation of tools. To do this, we need three wrenches: 12, 17 and 19 millimeters - and, of course, the silentblock itself.

Then proceed to repair. To do this, you need to lift the machine on the jack or put it on the flyover. We dismantle the wheel, then take the key to 17 and unscrew the 2 bolts securing the ball joint with the lower lever. Now go directly to the silentblock. In order to remove it, you must first unscrew the front bolt (the longest) and loosen the three others that are on the back of the part and on the transverse link. To do this, you need to use the keys at 12 and 19 millimeters. We dismantle the lower lever and remove the silentblock.

After this process, you can start installing a new spare part. Replacement of silentblocks is carried out to the same place where old parts were fastened. But for this you will need to use a lot of power. The fact is that removing an old spare part is not an easy task, as during the entire period of operation it can "stick" to the metal. In order to cope with this, it is necessary to lay it on some channel and after that knock out the old silentblock from the hammer with a hammer. And after it is knocked out, you can safely proceed to install a new part. Installation is carried out in the same way as dismantling, only in the reverse order.
