Why does the steering wheel always feel like it's leaning to the left?
2 Answers
The reasons for the steering wheel leaning to the left are as follows: 1. Most vehicles experience steering wheel deviation issues due to incorrect four-wheel alignment data or uneven wear and varying grip of the front tires. 2. If the vehicle exhibits driving deviation, misaligned steering wheel, or abnormal tire wear such as cupping or feathering, these issues are typically caused by incorrect four-wheel alignment data, necessitating a four-wheel alignment service. 3. However, some vehicles may experience changes in four-wheel alignment data after prolonged use or mileage accumulation. Even if the aforementioned issues are not present, it is advisable to perform a four-wheel alignment to prevent abnormal tire wear like cupping or feathering when replacing new tires. There are generally two main forms of vehicle deviation: 1. Braking deviation, where the vehicle's direction shifts when braking. 2. Driving deviation, where the driver must constantly hold the steering wheel to maintain straight-line driving under normal conditions. Some believe that if the vehicle does not move straight when the steering wheel is released on a flat road, it indicates deviation. This conclusion may not be entirely accurate. A practical tip is that if you constantly need to apply force to keep the vehicle straight during daily driving, it likely indicates deviation. If no such sensation exists, there is generally no issue.
Last time I drove, I also felt the steering wheel always pulling to the left, which reminded me of the problem I had with my old car ten years ago. There could be several possible reasons: First, uneven tire pressure—if the left front tire pressure is a bit low, the car will naturally drift to the left. Second, the wheels might be misaligned, which is the so-called wheel alignment issue, often occurring after hitting a curb. Third, the suspension system could be damaged, such as faulty shock absorbers, which can cause unstable steering. My advice is to first stop and check all tire pressures with a tire pressure gauge to ensure they are balanced on both sides. If the pressure is fine, then inspect the tire wear patterns. If the left side shows significant wear, it’s likely an alignment issue. Finally, you should take it to a professional shop for alignment calibration. Don’t delay this, as it can cause more noticeable shaking at high speeds and compromise safety.
