1. To make the car on the road on poor roads to travel 10km after parking, with the hands of the shock absorber shell, if not hot enough to show the internal resistance of the shock absorber, shock absorber does not work.
At this point, the appropriate lubricant can be added, and then the test, if the shell fever, the shock absorber internal lack of oil, should add sufficient oil; otherwise, the damper failure.
2. Press the bumper firmly, then loosen, if the car has a 2~3 jump, it shows that the damper works well.
3. When the car slow driving and emergency braking, if the car vibration more severe, indicating the problem of shock absorber.
4. Remove the shock absorber to erect it, and put the lower connection ring on the Vise, force pull and pressure to reduce the number of vibration, at this time should be stable resistance, to pull (recovery) resistance should be greater than downward pressure resistance, such as resistance instability or no resistance, may be the internal oil shock absorber or valve parts damaged, should be repaired or replacement parts.
