How to judge whether the shock absorber is invalid

The 1. shock absorber cylinder surface has oil isn’t really leak, judge the damper leakage failure, is according to the shock absorber type, leaking grade, oil leakage location and other factors to determine whether you need to replace. For a shock absorber with only slight leakage, no replacement can be made. In addition, it is normal for the shock absorber to have oil seepage in normal work.

2., if the shock absorber fails, it will not only affect the ride comfort, but also affect the stability. It will also affect the normal work of other components of the suspension, and even damage its life. If the oil leakage of the damper is invalid, it must be replaced. In addition, you can judge whether it is invalid,  please refer to the following methods:

1) when doubt shock absorber is invalid, placed the vehicle at a flat place, press the body. The body can not rebound more than 2-3 times, which is normal. The upper and lower quivers cannot be stopped very quickly, and the shock absorber is suspected to fail.

2) shock absorber in a vertical state with full hand push and pull 5 - 8 times; (inflatable shock absorber should be extended automatically ) to judge to push and pull feeling last 2-3: sense of shock absorber damping force of the shock absorber is normal, normal; sense of shock absorber damping force abnormal (inflatable shock absorber the piston rod does not rebound), damper failure;
