How to Determine if a Car is Pulling to One Side?

When driving on a flat road, take both hands off the steering wheel and drive straight for 100 meters. If the car does not drive in a straight line, it is pulling to one side. The reasons for a car pulling to one side are as follows: 1. Uneven load distribution: This mainly refers to whether the trunk has been carrying heavy items concentrated on one side. If so, moving them to the center can help. 2. Uneven tire pressure on both sides: The solution is to inflate both tires to the standard pressure. Additionally, check if the wear on both wheels is uneven, causing differences in wheel diameter and traction. 3. Damaged springs and shock absorbers: Focus on inspecting the lower side to see if the spring is overly compressed due to insufficient elasticity or if the shock absorber is leaking oil. If there are indeed issues, repair or replace them as needed. When replacing springs, always change both sides together; otherwise, it will create a new imbalance.
While driving, I pay attention to the steering wheel feedback to detect any pulling. Choose a flat, straight road, drive normally, then gently release the wheel for a second or two. If the car automatically drifts left or right, it's a clear sign of pulling. Uneven road surfaces can affect the results, so always test on a smooth road. The steering wheel turning on its own to one side is also a warning sign. Common causes include uneven tire pressure—I regularly check if all tires are properly inflated—or uneven wear on the tires causing imbalance. Loose wheel bearings or suspension system faults can also cause issues. During simple maintenance, checking tire pressure and visually inspecting tire conditions can help prevent or identify problems early. If I suspect pulling, I immediately schedule a professional inspection to avoid losing control at high speeds.
From daily driving experience, judging vehicle drift can be done through actual testing and observation. Find an empty straight road, release the steering wheel to see if the car naturally drifts; if there is drift, steering may feel heavy or unbalanced. External factors such as strong winds or road slope should also be ruled out. Tire issues are critical, as significant pressure differences can easily cause left-right pulling—I use a tire pressure gauge for regular checks. Uneven wear or aging tires can also cause drift, and wheel hub and bearing inspections should not be overlooked. Suspension system failures, such as damaged control arms, are another common cause. If drift is detected, don’t delay—visit a professional shop for diagnosis to ensure safe driving.
