Why are there so many abnormal noises when the cold car arrives at the chassis?
Loose chassis usually occurs in old cars. When the car is driving in bad road conditions, the steering wheel will feel unstable and the bottom of the car will make abnormal noise. Usually old drivers can feel that the whole car is a little loose. This situation indicates that the chassis may be loose, and there are several reasons for this. Only by understanding the reasons can we better prevent this problem.
The first reason is the aging of rubber parts. As we all know, rubber has excellent elasticity, which can cushion the friction between parts and reduce noise at the same time. There are rubber parts in many places on the car. However, this kind of thing has a long life, and it will age after a long time, and its elasticity is not as good as before, and its buffering capacity will decrease, resulting in abnormal sound in all parts, so it is necessary to check these rubber parts regularly and replace them in time.
The second possibility is a shock absorber. The main function of this component is to suppress vibration. When the car runs on the dustpan section, it will have an impact on the road surface, and the shock absorber can ensure the ride comfort of the car well. If the shock absorber is damaged, it will be tilted, resulting in loose chassis. Therefore, it is necessary to check the shock absorber more at ordinary times, and repair it in time if there is leakage.
The third is the gap between parts, which means that the ball head may be loose, and this part is like a human joint. If the ball head is loose, there will be a big gap between the lever and other connecting parts. If the gap is too large, the screws between the subframe and the suspension will become loose when passing through some dustpan roads, so the chassis will become loose. So check these two parts at ordinary times.
