The solution to the displaced shock absorber spring is to install the spring in the original position, the following is how to detect the quality of the shock absorber:
1. You can choose to drive a certain distance on a very poor road surface, and you can feel the shell of the shock absorber with your hands. If the internal heat is not felt enough, it can mean that the shock absorber does not provide resistance, that is to say, the shock absorber is not working, on the contrary, the shock absorber is working;
2. You can add some lubricating oil for testing, or choose a very poor road surface for driving, if the internal heat is not enough, it can mean that the shock absorber does not provide resistance, that is to say, the shock absorber is not working, on the contrary, the shock absorber is working. This can only be determined as the reason for the lack of lubricating oil in the shock absorber;
3. Press the bumper with your hand, if the car bounces back several times, it can prove that the shock absorber is normal, on the contrary, the shock absorber has failed;
4. Use the method of emergency braking to verify the quality of the shock absorber, if the car shakes more severely, it means that there is a problem with the shock absorber;
5. Disassemble the lower shock absorber and use the tool to pull and press it many times, if there is no resistance or the resistance is unstable, it means that the shock absorber spring is faulty.
