Does Not Returning the Steering Wheel to the Center Position Harm the Car?

Not returning the steering wheel to the center position can harm the car. The potential damages are as follows: 1. Damage to the steering system. If the steering wheel is not returned to the center position for a long time when parking, the wheels will forcibly pull the steering linkage, preventing it from returning to its original position. Both the steering wheel gears and the steering linkage rack remain under stress. While this may not cause immediate damage, prolonged exposure can lead to deformation of related components. Eventually, this can result in uneven tire wear and vehicle misalignment. 2. Damage to the suspension system. When the steering wheel is centered while parking, the suspension system is in a relatively relaxed state with balanced forces. However, if the steering wheel is not centered, it creates an angle, causing the suspension system to tilt in one direction. Over time, this can cause certain damage to the suspension system, such as accelerating component deformation and wear.

Last time I had maintenance at the 4S dealership, the service supervisor mentioned this issue. Keeping the steering wheel turned for extended periods actually harms the vehicle - it causes uneven pressure distribution on one side of the tires, just like standing crooked in high heels for too long will accelerate shoulder wear. The rack-and-pinion steering system also gets compressed on one side - that's exactly how my 8-year-old car developed steering gear oil leaks. Parking with wheels turned makes suspension ball joints and bushings bear extra stress, which you can feel through heavier steering. The mechanic advised developing the habit of straightening wheels when parked, which can extend front suspension life by at least two years.

All the long-distance drivers in our fleet know this. Not straightening the steering wheel after parking causes cumulative damage to the vehicle, primarily affecting three areas: uneven tire wear is the most noticeable, with sawtooth edges visible on the tire shoulders; the pressure bearings in the steering system wear out and produce abnormal noises; and the front shock absorbers leak oil faster due to uneven force distribution. Especially for vehicles with electronic power steering now, the motor being under prolonged strain can easily overheat and trigger warnings. Last year, our fleet's A6 had to replace the entire steering column assembly because of this, costing several thousand. It's fine if the wheels are slightly off for half an hour during daily parking, but it's best to straighten them overnight.

I've learned the hard way that not straightening the steering wheel can damage the car. I used to deliberately turn the wheels to squeeze into tight parking spots in my neighborhood. Half a year later, all four tires were worn out, with the outer tread of the left front tire completely gone, making it especially prone to slipping in the rain. The dealership inspection revealed that the steering gear clearance had also increased, and replacing the entire power steering unit would cost over 8,000 yuan. Now I've wised up—I always straighten the steering wheel when parking and reposition the car if the front wheels are off by more than 15 degrees. Regularly rotating the tires is also crucial; I recommend doing it every 5,000 kilometers.
