What are the reasons why a car's steering wheel does not return to center after turning?

Car steering wheel does not return to center after turning due to: 1. Uneven tire pressure between left and right sides; 2. Uneven tire wear on both sides; 3. Low vehicle speed; 4. Steering ball joints being inflexible or too tight. The car steering wheel consists of the steering wheel, steering shaft, and steering column. The working principle of a car steering wheel is to transmit torque to the rack-and-pinion mechanism by turning the steering wheel, thereby pushing the wheels to turn left or right; the longer the rack pushes, the greater the angle of tire rotation. The function of the car steering wheel is to control the driving direction of the vehicle and manipulate the steering wheels, enabling the car to drive straight or turn.
After driving for so many years, I often encounter situations where the steering wheel doesn't automatically return to center after turning. The main reasons are wear in the steering system gears or loose tie rods, which increase friction and prevent it from returning to position. Tire issues like uneven pressure or uneven wear also affect balance, causing steering resistance. I remember last year when driving on mountain roads, the steering wheel got stuck, and inspection revealed it was due to worn shock absorbers. If not addressed promptly, it can accelerate part wear and increase driving risks, especially when handling becomes sluggish during high-speed cornering. It's recommended to check tire pressure monthly and visit a professional shop for a four-wheel alignment check to ensure safe driving.
