Why does the new Baojun 730 make abnormal noises when turning the steering wheel back and forth?

[McPeyton]

Steering wheel abnormal noises may be caused by insufficient lubrication of the steering column, low power steering fluid, issues with the universal joint, or damage to the plane bearing. Steering wheel principle: Many vehicles now have vacuum assist, which only reduces the driver's control effort but does not change the force on the steering gear itself. Therefore, an effective way to reduce steering wheel wear is to minimize the load on the steering wheel during operation. Safety hazards caused by aging: Car enthusiasts should develop the habit of turning the steering wheel only after the wheels start moving. This reduces the friction resistance between the tires and the ground, lessens the excessive load on the steering gear and the excessive wear of the steering linkage system, which can cause abnormal noises when turning the steering wheel. Long-term stationary steering: This not only places a heavy load on the steering gear but also accelerates the wear on the tire surface, reducing the tire's service life. The method to change this habit is: Quickly turn the steering wheel when the wheels are slightly moving to achieve the purpose of control.
