The abnormal sound of the shock absorber dust jacket needs to be checked to see whether the shock absorber leaks oil or there is a problem with the pressure bearing on the cover of the shock absorber. Timely replacement can solve the problem. Specific methods are as follows:

1, the first direct listening. At low speed, if the tire passes through a convex area, there will be a slight sensation accompanied by the sound of 悾悾. And the sound is very dull, at this time we can rely on experience to judge which suspension is issued, and then go further to check whether there is any damage, if there is no damage, do not move, go to the repair shop to test.

2, the next is to see whether the shock absorber is leaking oil, in the absence of rain or not washing the car, to see whether there is oil on the shock absorber shell or dust jacket, this is obviously directly can be seen.

3, the final is to touch with the hand, with the hand pressure above the suspension, such as the front and rear wing sub-plate. If there is a problem, the shock absorber will be hard, generally caused by the shock absorber oil leakage for a long time, but also need to be treated.
