Shock absorbers are very important for driving on bumpy roads. Automobile shock absorbers are generally installed on the automobile suspension system. If the shock absorber does not work properly, it will lead to a reduction in the life of parts of the car, and also greatly reduce the smoothness of the car. When driving a long distance and passing more uneven roads, check whether the shock absorber can work properly.
Here is how to check the efficiency of the shock absorber:
1. You can drive at a low speed first, then brake hard. If you find that the car shakes badly and the human body feels uncomfortable, then there is a problem with the shock absorber.
2. Press the bumper firmly and then release it. If the car has 2-3 jumps, it means that the shock absorber is working well.
3. Make the car stop after driving 10km on the road with poor road conditions, and touch the shock absorber shell by hand. If it is not hot enough, there is no resistance inside the shock absorber and the shock absorber is not working. At this time, you can add appropriate lubricating oil, and then carry out the test. If the shell heats up, there is a shortage of oil inside the shock absorber, and enough oil should be added. Otherwise, it means that the shock absorber has failed.
4. Remove the shock absorber and stand it upright, and clamp the lower end connecting ring to the vise. Pull and compress the damping rod several times, and there should be stable resistance at this time. The resistance of pulling upwards should be greater than the resistance of pushing downwards. If the resistance is unstable or there is no resistance, it may be due to lack of oil inside the shock absorber or damage to the valve parts. This should be repaired or replaced parts.
