How to judge that the top rubber is broken, and how often should the shock-absorbing top rubber be replaced?

In addition to the shock absorber itself, the common damage of automobile shock absorbers also includes the damage of the shock absorber top rubber. Under normal circumstances, we do not need to replace the shock-absorbing top rubber regularly. If the following fault conditions occur, it needs to be replaced.

Abnormal sound:When the shock-absorbing top rubber is damaged due to severe abrasion, the vehicle shock absorber will make an abnormal noise when it is working.

Direction offset:When the shock-absorbing top rubber is damaged, the direction of the vehicle may be slightly shifted, it is difficult to return to the center, and the return strength is low.

The noise becomes louder:Due to the lack of the cushioning of the top rubber, the shock absorber will transmit the absorbed vibration and impact from the frame to the cabin without reservation.

Turning in place, abnormal noise:Even if the shock absorber is not working, due to excessive wear and damage of the top rubber, moving the steering wheel in place will make a very obvious abnormal noise.

Through the above failure conditions, we can also determine whether the shock-absorbing top rubber is damaged. If the shock-absorbing top glue is abnormal, it will still have a great impact on the driving stability of the car. Because the shock absorber top rubber is the spring base on the top of the shock absorber assembly, which is made of rubber material, and it mainly serves as a buffer.

During the working process of the shock absorber, the shock from the road surface is converted by the shock absorber spring into the repeated bounce motion of the spring. At the same time, the shock absorber refines and accelerates the attenuation of the natural vibration of the spring, and finally the shock absorber is used as the top rubber. The final cushion is transmitted to the body.
