What are the reasons for the unstable direction of cars on highways

What"s wrong with an unstable steering wheel when a car is running on the highway?

In general, steering wheel shaking occurs during high-speed driving of a car. There are only the following reasons* 1、 Have you ever repaired or replaced a tire recently? If so, it is recommended to perform dynamic balancing on all four tires. Secondly, the clearance between the steering wheel ball joint and the swing arm is too large.

Most of them are caused by deformation or poor performance of vehicle suspension system related components. On the one hand, it is related to the working performance of shock absorbers and shock absorber springs. The deformation of shock absorbers and the decrease in spring elasticity of shock absorbers can cause changes in the height of the vehicle body.

Analysis and handling: This situation is mostly caused by deformation of the tire due to friction, collision, or aging during daily use. Simply replace the tire. Fault 4: Sudden steering wheel shaking during high-speed driving.

Common causes of car deviation: (1) Changes in the parameters of four-wheel alignment can be achieved by performing four-wheel alignment processing
