What to Do When the Car Pulls to One Side?

If the car pulls to one side, first check whether the tire wear is even under normal tire pressure, and replace the tires in time if there is a problem. Then check whether the lower control arm, ball joint, and CV joint are normal. If everything is normal, you can only perform a four-wheel alignment first and then make corresponding adjustments. You can also adjust the tie rod to solve the car's pulling problem. Here are the specific reasons for the car pulling to one side: 1. The tie rod is an important part of the car's steering mechanism, which directly affects the stability of the car's handling, the safety of operation, and the service life of the tires. Secondly, check the stabilizer bar and steering gear. The steering gear may be mechanical and worn too much, or the steering tie rod may have excessive clearance. All these should be checked before alignment. If no parts are damaged, it may be that the steering gear has excessive clearance, and the misaligned steering wheel can be corrected by adjusting the toe-in. If the steering gear is problematic, it can also be replaced. 2. When the front shock absorber springs are deformed and the damping on both sides is inconsistent, it can also cause the car to pull to one side. The condition of the shock absorber springs can be judged by pressing or comparing after disassembly. When the front shock absorber fails, the two suspensions are at different heights during driving, resulting in uneven force distribution and causing the car to pull to one side. The absorption of the shock absorber can be tested with a special testing device to determine its condition. If disassembly is not possible, the condition can be judged by stretching.

Just helped a neighbor with a similar issue yesterday. If you notice the steering wheel consistently pulling to one side, first pull over and perform a simple check. Uneven tire pressure is the most common cause—especially when the difference between left and right tires exceeds 0.5, it noticeably drags the steering. Tires worn into a one-sided sawtooth pattern or with bulges can also cause this. Next, inspect the rims; last week, I encountered a case where an inward deformation of the rim caused steering pull. Also, check for loose steering ball joints—have someone turn the steering wheel left and right while the car is stationary, and look underneath for any movement in the tie rods. The most unexpected case I've fixed was a small stone stuck in the steering gear teeth, which was resolved by simply removing it. Remember to address this immediately—last year, there were two accidents caused by sudden worsening of steering pull leading to collisions with guardrails.

Always having to pull the steering wheel hard on the highway? I know this too well. Last year, driving my old Jetta on a long trip, my arms would ache every half hour—turned out the right front shock absorber was leaking, causing the front end to tilt. My advice: first, find a straight road, let go of the wheel for about a hundred meters. If the car drifts more than a lane width, it's dangerous. Irregular tire rotation can also cause this—I cross-rotate mine every 8,000 km. Many overlook aging steering system bushings; cracked rubber increases steering play and messes up alignment. If you’ve modified the suspension, check it extra carefully. Once, helping a friend adjust coilovers, a mere 3mm height difference between sides made the car pull. When getting an alignment at a tire shop, keep an eye out—some workers can’t even set the caster angle right.

Over 30 years of car repair, I've summarized a four-step method for diagnosing alignment issues. First, test drive on level ground—release the wheel at 50 mph to observe drift speed. Second, check tire pressure—differences between cold and hot readings exceeding 0.3 bar indicate problems. Third, inspect brake calipers—once encountered a seized slide pin causing uneven braking. Fourth, examine suspension components—lower arm bushings crack more frequently than ball joint failures. Last week fixed a Tesla with metal shavings in wheel speed sensors disrupting EPAS. Older cars need steering gear play checks—the worst rack wear I've seen was 5mm. Pro tip: bring cigarettes to veteran mechanics—they'll use jacks to simulate loaded suspension adjustments.
