What are the reasons for a car pulling to the left or right?

[MacJosie]

The reasons for a car pulling to the left or right are: 1. Inconsistent braking force between the wheels on both sides of the car, especially the wheels on both sides of the steering axle; 2. Uncoordinated movement of the suspension guide rods and steering system tie rods during braking; 3. Improper loading on both sides of the vehicle; 4. Inconsistent road surface adhesion on both sides. The phenomena of a car pulling to the left or right include: 1. The car drifts irregularly to the left or right while driving, or exhibits regular directional pulling; 2. The rear axle slides sideways or the front wheels lose steering ability, causing the car to lose control and deviate from its original direction; 3. The body sways during braking; 4. The steering wheel feels like it is being pulled.

I think the common reasons for a car pulling to one side are uneven tire pressure or uneven tire wear. If the pressure is higher on one side and lower on the other, the car naturally pulls toward the side with lower pressure. Uneven tire wear works similarly—if one side is more worn, it pulls the car to that side. Issues in the suspension system, such as a broken shock absorber or aged springs, can also affect steering because the wheels can't properly balance impacts. Additionally, incorrect wheel alignment—like camber or toe angle deviations—is a long-term factor that can lead to persistent pulling. When checking, I start with the simple solutions: inflating the tires or replacing them. If that doesn’t work, I take the car to a repair shop for a four-wheel alignment. I also check tire pressure and tread depth monthly to prevent small issues from becoming big ones, saving both hassle and money while ensuring safety.

Vehicle misalignment often stems from suspension or wheel alignment issues. Worn suspension components like leaking shock absorbers or loose control arms can cause wheels to drift uncontrollably. Incorrect alignment settings such as improper four-wheel adjustment make straight-line driving difficult. I recommend regular professional four-wheel alignment checks rather than waiting for abnormal noises to appear, as suspension problems can be hidden hazards. While stuck brake systems may also cause pulling, misalignment during driving is typically not brake-related. For safety, promptly inspect wear points like tie rods or ball joints to avoid long-distance driving risks. Developing an annual maintenance habit helps prevent potential issues proactively.

Car pulling to one side must be taken seriously, with tires being the key factor: differences in air pressure or uneven wear can easily cause deviation; wheel imbalance or deformation can also lead to it. Incorrect alignment worsens the problem; suspension damage is even more dangerous. I recommend immediately checking tire pressure and wear, paying attention to steering wheel feedback during daily driving, and seeking repairs if any abnormalities are noticed, prioritizing driving safety.
