What are the reasons for a car steering wheel not returning to center?

[VanTalia]

There are several reasons why a car steering wheel may not return to center: 1. Damage to the steering gear or excessively tight steering gear bolts causing the steering not to return; 2. Low tire pressure, incorrect front wheel alignment or improper camber angle; 3. Poor lubrication between the kingpin and bushings; 4. Lack of or leakage of steering fluid in the steering system. The steering wheel is connected to the steering shaft via splines, and its function is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft. Using a larger diameter steering wheel reduces the hand force required from the driver when turning. The steering intermediate shaft, acting as a connecting component between the steering gear and steering shaft, facilitates the standardization of steering gears, compensates for manufacturing and installation errors, and enables more rational installation of the steering gear and steering wheel in the vehicle.
