What are the reasons for slow steering wheel auto-return?
2 Answers
Here are the explanations for the reasons behind slow steering wheel auto-return: 1. Uneven tire inflation on both sides: Uneven inflation of the left and right tires, with inconsistent tire pressure, is one of the main causes of weak return force. To diagnose this issue, a tire pressure gauge must be used. Kicking the tire tread can only provide a rough estimate of the tire pressure condition. The reason uneven tire pressure prevents the steering wheel from returning to center is that the side with lower pressure has a wider contact patch with the ground, naturally encountering greater road resistance, causing the car to veer toward the side with lower pressure. In this case, the tire pressure on both sides should be readjusted to ensure uniform inflation. 2. Uneven tire wear on both sides: Significant differences in tire wear between the left and right wheels, along with uneven inflation, can cause the steering wheel to pull to one side. This issue can usually be addressed by rotating the tires. To resolve steering pull and extend tire lifespan, tires should be rotated every 10,000 kilometers.
Slow steering wheel return is mainly related to the steering system. I've driven many cars, and when encountering this issue, it's often due to insufficient power steering pump or fluid, resulting in inadequate assistance and difficulty in returning to center. Additionally, significant four-wheel alignment deviations, such as improper camber settings, can make the steering wheel less responsive. Uneven tire pressure or irregular wear can also slow down the return. I've checked myself; you can start by inspecting the tire condition and then have a professional shop test the power steering pressure. If not repaired promptly, it can lead to loss of control during turns, increasing the risk of accidents. It's best to develop a habit of regular maintenance, such as an annual alignment check, which can save a lot of hassle and improve handling.
