The driver must be at each motorist

Silentblock, or rubber-metal hinge - a unit consisting of two metal bushings and an elastic insert between them, but structural changes are possible depending on the specific intent of their use.

In the compounds, due to the rubber-metal hinge, negative vibrations and jerking occur. It is installed in various places of the suspension, experiencing more wear. As a result, the replacement of the silentblocks should be made more often than of the suspension parts (for this use a silencer puller). These are the levers of the front and rear suspension. Also, silent blocks are used for resilient fastening of shock absorbers, jet links and stabilizer of lateral stability.

Terms of service

The lifetime of the silentblock depends on a number of factors: the degree of stresses experienced by the vehicle suspension; From the workload of the part on which it is installed, as well as on the quality of the silentblock itself. It must be remembered that the replacement of these parts should occur symmetrically: by changing the silentblock of the right lever, at the same time it is necessary to replace it with the left one. Otherwise there will be premature wear of the parts due to the uneven load on the suspension parts.

It is possible to notice the wear of the silentblock visually. It is necessary to control the state of the internal filler: if the rubber or polyurethane elastic insert has cracked, cracks or delaminations appear on it, then the silicone block must be changed immediately!

If the car starts to move to the side at high speed, there are additional problems with the control, then, probably, the reason for this was the worn out silentblock. Removable silicone block universal will help you to do everything yourself.

Do you have a car VAZ? So, we need a special puller for the silencers VAZ.

Uneven abrasion of tires can also speak of premature wear of the rubber mount. Inspection of silent blocks in the conditions of Russian roads should be carried out every 50 thousand km, and replacement at the suspension nodes experiencing the greatest deformation - every 100,000 km.

Process Features

Replacement of the silentblock is carried out by a special puller, which gently pushes it out of the general holder. Knocking out the part with improvised tools can lead to negative deformations, as well as unnecessary mechanical stress in the welding places. That's why you need to use a silencer puller. Before installing a new part, the working surface of its casing must be cleaned from dirt and greased.

There may be problems with pressing a new silentblock into the workpiece of the part without special tools - replacing with your own hands often damages the elastic insert. As for work in the engine or gearbox, it is highly discouraged to act independently here. It is better to consult competent specialists with experience in similar works.

Why you need to use quality parts

The use of substandard products can lead to rapid wear and breakage of suspension elements. Voltage running will increase, and the service life will be significantly reduced if the elastic filler is too soft or too hard.

Recently, polyurethane fillers with a longer service life are more popular, but they are quite expensive compared to simple rubber ones. Buying them is justified only in cases of uniform wear and tear of the car suspension parts, while the conjugate parts are in good condition. This will ensure a smooth running of the vehicle and a long service life of the undercarriage elements under constant load.
