Common fault of shock absorber

Shock absorber is a vulnerable part in the process of vehicle operation. The work of shock absorber will directly affect the stability of vehicle running and the life of other parts. Therefore, we should make the shock absorber always in good working condition. The following methods can be used to test the good work of the shock absorber.


1, make the car run on the road with poor road conditions for 10 kilometers, then Park and touch the shell of the shock absorber. If it is not hot enough, it shows that there is no resistance inside the shock absorber, and the absorber doesn't work. At this time, an appropriate lubricating oil can be added and tested. If the shell is heated, the oil inside the shock absorber should be filled with enough oil. Otherwise, the shock absorber will fail.


2, press the bumper, then release, if the car is 2-3 times jump, then the shock absorber works well.


3, when the car is slow driving and emergency braking, if the vibration of the car is more violent, it indicates that the shock absorber has problems.


4, remove the shock absorber and the lower end of the upright, the connecting ring clamped in a vise, pull pressure damping rod several times, at this time should have a stable resistance, pull up, restoration resistance should be greater than the downward pressure resistance, such as resistance instability or no resistance, may damage internal shock absorber oil or the valve parts, should replace or repair parts.
