If the car shock absorber makes an abnormal sound, it means that the car shock absorber is damaged and must be replaced. If the temperature of the two car shock absorbers is different and the difference is large, or the friction resistance of the car shock absorber is small or no, it is usually due to lack of oil or damage to the precision parts of the gate valve.

1. Stop after driving 10 kilometers on a road with weak real-time road conditions, and touch the metal shell of the car shock absorber with your hand. If it is not hot enough, it means that there is no friction resistance in the internal structure of the car shock absorber, and the car shock absorber does not work. At this time, you can add appropriate lubricating oil and test again. If the metal shell is hot, it means that the oil in the car shock absorber is less and should be refueled. Otherwise, the car shock absorber will fail.

2. Press the front bumper of the car lightly and then release it. If the vehicle jumps 2~3 times, it means that the car shock absorber is working well.

3. When the car is driving slowly and stops in an emergency, if the vehicle vibrates strongly, it means that there is a problem with the car shock absorber.

4. At this time, there should be a stable friction resistance, and the friction resistance of pulling up is greater than the friction resistance of pressing down. If the friction resistance fluctuates or there is no friction resistance at all, it may be that there is too little structural oil in the car shock absorber or the precision parts of the gate valve are damaged and need to be repaired or replaced.
