Why is there an abnormal noise after replacing the shock absorber?

As we all know, the shock absorber is mainly used to suppress the shock when the spring rebounds after shock absorption and the impact from the road surface. When passing through an uneven road, although the shock-absorbing spring can filter the vibration of the road, the spring itself will have a reciprocating motion, and the shock absorber is used to suppress this spring jump. Many car owners have responded that after replacing the shock absorber, there will still be different degrees of abnormal noise?

1. Bad driving habits
In daily driving, you should slow down when you encounter speed bumps, try to avoid large potholes, or make sharp turns in high-speed sections. These bad driving habits are also the reasons for the abnormal sound of oil leakage of the shock absorber.


2. Lack of shock absorber parts

Most car owners choose to directly replace the shock absorber core when replacing the shock absorber. In fact, as the service life of the vehicle increases, many accessories of the shock absorber have been damaged or disappeared, such as the buffer block, when the technician disassembles the shock absorber It was found that the buffer block was not installed! Can I remember that the buffer block was installed before~ What is the reason? That is because the buffer block is made of polyurethane foam, which will crack and decompose during the continuous impact process. As the service life of the car increases, when the owner replaces the shock absorber, the buffer block has completely decomposed and disappeared.

The lack of parts will accelerate the overall damage of the shock absorber. Therefore, when replacing the shock absorber, be sure to check the relevant parts of the shock absorber in detail to ensure a comfortable ride.


3. Excessive modification

Many car owners pursue the driving control and grip of the vehicle, and like to modify the vehicle lightly, especially the products that lower the body are very popular, but if the vehicle is excessively modified, the lowering of the vehicle exceeds the tolerance of the car itself, and the chassis is too low, which will accelerate the shock absorption. The wear and tear of the device will cause abnormal noise, because Xiaoli recommends that when refitting the vehicle, the lowering degree of the body is controlled within 30-40mm for the best effect;


1. Maintain good driving habits, slow down with speed bumps, avoid large potholes, and avoid high-speed turns;

2. Refuse to match the old and new, directly replace the shock absorber assembly, new accessories, save time and worry;

3. Regularly check the quality of the shock absorber. The American Society of Automotive Engineers recommends that the shock absorber should be checked in time every 2w kilometers of the vehicle, and the shock absorber assembly should be replaced in time every 8w kilometers!
