What are the reasons why the steering wheel cannot automatically return to center?

[RichardDella]

Here are the reasons why the steering wheel cannot automatically return to center: 1. Poor lubrication between the kingpin and bushing: After prolonged use, severe wear can lead to excessive clearance. At this point, the front wheel camber angle may disappear or turn into negative camber. When the front wheels tilt inward, the axis of the front wheels and the kingpin become nearly parallel. This increases the resistance arm during steering, preventing the kingpin inclination angle from functioning effectively. 2. Damage to the chassis or deformation of the suspension causing tire misalignment on one side: If the steering wheel cannot return to center at all when turned to one side, the problem is more serious. In this case, merely performing a wheel alignment is insufficient. When this occurs, 80% of the time the vehicle has experienced a significant collision. Therefore, a comprehensive inspection and repair of the vehicle is necessary to prevent further issues or even accidents during subsequent driving.
