General shock absorber damaged with the following fault embodiment:

1, damper oil seepage.

Normal damper outer surface is dry and clean, if there is oil seepage, indicating that the damper inside the hydraulic oil from the upper end of the piston rod out of the damper, this kind of situation has been invalid on the general damper;

2, the vehicle over the bumpy ground or speed bumps, a wheel "bang" sound, indicating that this wheel on the vibration damping effect of the damper is not good or ineffective;

 3, the vehicle in the curve significantly that the body tilts sideways to add, if prohibited, and even produce side slip, which is mostly due to the damping force of the damper is too small, can not effectively inhibit the compression of the spring;

4, the vehicle in the bumpy road conditions after driving for a while, with a hand to touch each damper shell, experience the temperature of the damper, under normal circumstances, the damper shell is warm, if a damper shell is cool, indicating that the damper has been damaged;

5, the vehicle in the state of stopping, when the vehicle body corner to the downward pressure and release, the vehicle body in the spring force will rebound, if the rebound soon after the maintenance of stability, that the damper is good; if it is a constant vibration a few times before stopping, it is shown that the vibration damping effect of the damper part of the poor.
