How is the rear silentblock of the front lever arranged and how much does it serve?

Rear silentblock of the front lever is one of the components of the running gear of the car. It refers to the guide elements of the suspension and, together with the levers, suffers enormous loads from the wheels. However, along with this, this element has a lot of differences. Which are in our article.

Why silentblock?

In translation from English, "silent" means "quiet." And this name was given to him for good reason. The fact is that the main function of this spare part is to eliminate oscillations that are transmitted from one node to another. Thus, reducing the resistance force, it contributes to the quiet and smooth running of the car. The machine, in which the rear silentblock of the front lever has failed, begins to make fatal sounds. An annoying creak is heard - it's time to change the part.

What is he like?

Silentblock is 2 steel bushings, between which is placed a rubber insert. Actually, because of this design, it received its second name - rubber-metal hinge. Tremendous loads suffer both components, therefore back silent blocks of forward bottom levers never are repaired and repair kits on them are not present. They change entirely.

Material

If the inner part of the rubber block consists of steel, the outer part is made of high-strength polyurethane. The rubber composition of each manufacturer is different, so the price and service life of each part is appropriate.

Life time

The rear silencer of the front arm can serve for very long, up to 100 thousand kilometers. However, now the market has a lot of substandard parts that can not withstand 50 thousand kilometers. After this, the rear silencer of the front lever is replaced. But in general, the life of this part is in the range from 70 to 100-110 thousand km.

How to determine the current state of a part

To determine the serviceability of the silentblock, it is not necessary to go to the service station and contact the services of professionals. Inspection and diagnosis of this part can be made independently. Usually Russian motorists check the condition of silent blocks every 50 thousand kilometers. Given the condition of our roads is the maximum, how many parts can hold, as a rule, cheap. So, first, you should make a visual inspection of the device and make sure the integrity of the hinge. No rubber peelings should form on the rubber block. Next, we check the backlash of the part. If the rubber on the silent block breaks down or the mechanism itself loops, an urgent replacement should be made. The entire installation process is not very difficult, with the exception of crimping. Here you need to apply special knowledge, tools and skills. In the rest everything should pass easily and quickly. But after you press in the new rear silencer block of the front lever and collect all the parts in place, do not forget to make the wheel alignment-convergence.

Ignore the replacement of this part is not worth it, because the consequences can be not only an exhausting creak while driving, but also uneven wear of the tires.
