Car steering wheel jitter is very common. Some car owners can feel the steering wheel shaking strongly when driving at high speed, when the speed reaches above 80-100 km/h. This situation is mostly caused by the problems of automobile tires, because the uneven mass distribution of various parts of the tires will cause the dynamic imbalance of the wheels after high-speed rotation, which will lead to serious steering wheel jitter when the automobile is driving. In this case, it is necessary to carry out four-wheel positioning and dynamic balance of automobile tires, and even replace the tires in serious cases.

In addition to automobile tires, it is also possible that the shock absorber is invalid, the frame is deformed, and the meshing gap between the driving and driven gears of the main reducer is too large. If the steering wheel vibrates when braking while driving, it is likely that the braking force is too strong and the frequency is too high, resulting in overheating and deformation of the brake disc and brake pad when it is cold, resulting in steering wheel jitter.

Generally, replacing the brake disc and brake pad can solve the symptoms. If the vehicle speed is not fast, but the steering wheel shakes, it may be that the steering belt of the mechanical steering system is too loose and the steering wheel shakes when the steering transmission system is too loose, but this situation is rare.
