There are several reasons that may cause the steering wheel to pull to the left when driving straight: 1. Abnormal tire wear or uneven wear: When the vehicle's tires exhibit abnormal or uneven wear patterns, the tire contact surface becomes tilted, leading to misalignment or pulling to one side. 2. Uneven tire pressure: If the tire pressure is inconsistent, the vehicle will tend to pull toward the side with lower pressure, causing the steering to drift when driving straight. 3. Incorrect four-wheel alignment data: Inaccurate four-wheel alignment can also result in steering misalignment. Causes of incorrect alignment data include deformation or loose ball joints in the tie rods due to severe jolts, which affect the front toe-in value and cause the vehicle to pull to one side. Additionally, damaged ball joints or bushings in the upper or lower control arms can affect the camber angle, leading to uneven tire wear and indirectly causing steering misalignment and pulling.

I've encountered this situation several times before. The steering wheel tends to pull to the left when driving straight, which is mostly caused by issues in the wheel system. For example, uneven tire pressure—if the left front tire has too low pressure, it will pull the car to the left. Another possibility is incorrect wheel alignment, where improper toe or camber angles cause the car to drift. Aging suspension components are also a common factor; worn ball joints or shock absorbers can affect balance. I recommend regularly checking tire pressure to ensure both sides are equal. If the problem persists, it's best to get a four-wheel alignment at a repair shop to prevent premature tire wear and handling safety issues. Ignoring what seems like a minor problem could lead to major failures and compromise driving safety, so don't take it lightly.

I also experienced the annoying issue of the steering wheel pulling to the left after driving my car for a few years, and it almost caused trouble once on the highway. Based on experience, it was likely caused by uneven tire wear, such as severe tread wear on the left front tire or low tire pressure. Other possible causes include loose suspension components like control arms or the influence of uneven roads. When dealing with it, I first checked the tire pressure myself and only went to a technician for alignment inspection after confirming there were no issues. These small problems can accumulate and become very dangerous. I recommend you regularly check your tire condition and perform timely maintenance to avoid a lot of trouble. Safe driving should always come first—don’t wait for an accident to take action.

This issue is actually quite simple to address. When I DIY car repairs, I often find that a left-leaning steering wheel is usually caused by tire issues, such as uneven tire pressure or asymmetric wear. Aging suspension systems, like worn-out shock absorbers, can also make the car pull to one side. Checking isn't complicated: use a tire pressure gauge to ensure all tires have consistent pressure; if that's fine, then check the wheel alignment. As an enthusiast, I recommend timely adjustments to prevent worsening. A simple DIY fix can help maintain safety.
