What are the reasons for the steering wheel automatically pulling to the left?
2 Answers
The reasons for the steering wheel automatically pulling to the left are: 1. Insufficient tire pressure. When a tire lacks sufficient pressure, its rolling resistance increases, causing the vehicle to pull to one side; 2. Wear or damage to the chassis suspension system, leading to abnormal four-wheel alignment data, which results in the vehicle pulling to one side; 3. Uneven tire wear causing differences in tire tread patterns. The steering wheel is a wheel-shaped device used to control the direction of cars, ships, and airplanes. Its function is to convert the force applied by the driver on the edge of the steering wheel into torque and transmit it to the steering shaft. It mainly consists of a frame, foam, and the driver's airbag.
I often drive to and from work, and the steering wheel automatically pulling to the left is mostly caused by low tire pressure in the left front tire. Uneven tire pressure leads to an unbalanced contact with the road surface, naturally causing the car to pull left. Additionally, improper wheel alignment is quite common—misadjusted front wheel angles, such as toe issues, can result in drifting. Suspension system failures, like a broken shock absorber or a bent steering tie rod, can also cause this, especially if you've previously hit potholes or curbs. When tire wear is uneven, with the left side more worn, the car will also pull left. I encountered this issue last week—I first checked the tire pressure with a gauge, then went to a shop for a four-wheel alignment to fix it. If not repaired promptly, an unstable steering wheel can easily lead to loss of control and accidents at high speeds, while also increasing fuel consumption and tire wear. During maintenance, remember to prioritize checking these simple factors first. Regular maintenance, such as inspecting the suspension and alignment every 5,000 kilometers, can prevent most drifting issues. Driving safety comes first.
