The rear arm of the front arm is one ofcomponents of the undercarriage of the car. It belongs to the guiding elements of the suspension and, together with the levers, suffers enormous loads from the wheels. However, this element has many differences. Which - further in our article.
Why silentblock?
Translated from English "Silent" means"quiet". And this name was given to him for a reason. The fact is that the main function of this part is to damp 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, which has failed the rear silent block of the front lever, begins to make heart-rending sounds. An annoying creak is heard - it's time to change the detail.
What is he like?
The silent block is 2 steel bushings, betweenwhich is placed rubber insert. Actually, because of this design, he got his second name - the rubber-metal hinge. Enormous loads endure both components, therefore the rear silent arms of the front lower arms are never repaired and there are no repair kits for them. They change completely.
Material
If the inner part of the Hob consists ofsteel, the outer 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
Rear Hob front lever can servevery long, up to 100 thousand kilometers. However, now there are a lot of low-quality parts on the market that cannot withstand even 50 thousand kilometers. After this, replacement of the rear Hb of the front arm is required. But in general, the service life of this part is in the range from 70 to 100-110 thousand km.
How to determine the current state of the part
To determine the health of the silent block,it is not necessary to go to the service station and use the services of professionals. Inspection and diagnosis of this part can be made independently. Usually, Russian motorists check the condition of the silent blocks every 50 thousand kilometers. On condition of the condition of our roads, this is the maximum, how many details can last, as a rule, are cheap. So, first you need to make a visual inspection of the device and ensure the integrity of the hinge. The rubber block should not be formed on the silent block. Next, check the backlash details. If the rubber on the silent block is exfoliated or the mechanism itself is loosening, an urgent replacement should be made. The entire installation process is not very difficult, with the exception of pressing. Here you need to apply special knowledge, tools and skills. Otherwise, everything should go quickly and easily. But after you press-fit the new rear silent block of the front lever and assemble all the parts into place, do not forget to align the wheels.
Ignoring the replacement of this part is not worth it, since the consequences can be not only a heart-rending creak while driving, but also uneven tire wear.
