The steering wheel of the car is shaking badly. What is the reason?

Steering wheel jitter can be divided into two situations, one is the jitter at idle speed, which is slight but not very strong. The other is the jitter during driving, especially when the speed is fast. The causes of these two kinds of jitter are different.

Let's talk about idle jitter first. Generally speaking, there is jitter when idling, and the problem will not be too big. Most of the reasons are caused by loose steering wheel bolts or rubber sleeves.

The owner will pay attention to the shaking of the vehicle during driving. The reason for this situation is basically caused by unbalanced dynamic balance. Generally speaking, the higher the vehicle speed, the more serious the jitter. Because of the problem of dynamic balance, the tire will lose its balance and jump during rotation. The steering wheel is connected to the tire, and this jumping force is transmitted to the steering wheel through the transmission shaft, which causes the steering wheel to shake. Therefore, steering wheel jitter is a signal of abnormal vehicle dynamic balance.

At this time, it is necessary to go to the 4S shop or repair shop for testing as soon as possible to confirm whether it is caused by dynamic balance, and then carry out maintenance. There are many reasons for the abnormal dynamic balance, which may be that the lead block falls, the tire hub is hit, or it may be that the tire does not change position for a long time and does not pay attention to the tire pressure, resulting in uneven tire wear.
