Why does the car still pull to one side when the four-wheel alignment data is correct?
3 Answers
The four-wheel alignment data is correct but the car still pulls to one side because the tire tread patterns on both sides are different or the tread depth is uneven. Below is relevant information about tires: 1. Tire Introduction: Tires are the only components of a car that come into contact with the ground. Some car owners only replace the tires on the drive wheels when changing tires. For example, some front-wheel-drive car owners only replace the two front tires, while some rear-wheel-drive car owners only replace the two rear tires. In fact, this practice is acceptable. 2. Tire Aging: Tires are rubber products and will age over time. It is recommended that car owners replace their tires every four years, even if the mileage is low. Tires can also age if left unused for long periods, so it's important to check the production date when purchasing new tires.
As an ordinary car owner with years of driving experience, I've encountered situations where the alignment data was correct but the car still pulled to one side, which was quite frustrating. That time I went to the 4S shop for wheel alignment and they said everything was normal, but on the highway when I let go of the steering wheel, it pulled sharply to the right – terrifying! Later I discovered there was a significant difference in tire pressure between left and right, with the left front tire being 5 psi low. Further inspection revealed that the rubber bushings on the rear suspension shock absorbers had aged, causing the car to pull unconsciously. My suggestion is to start with the basics: first check if all four tires have equal pressure, and observe whether tire wear is even or if one side is deeper than the other. If these are ruled out, promptly inspect suspension components like springs or control arms, as wear in these parts can also compromise alignment effectiveness. Most importantly, safety first – don't stubbornly drive a pulling car. Finding a reliable repair shop for a comprehensive suspension system inspection is the right way to go.
I think the alignment data is correct but the car pulls to one side, the issue likely lies in additional factors like tires or suspension. Uneven tire pressure is the most common culprit—even a slight difference can cause handling imbalance. Personally, I regularly check the dashboard tire pressure readings. Another possibility is uneven tire wear, such as excessive wear on the front tires. Even with perfect alignment, uneven friction can pull the car off course. Worn or damaged suspension bushings could also be to blame, as they destabilize wheel positioning. Steering system faults, like loose tie rods, might not show during alignment but reveal themselves while driving. I recommend inspecting key wheel and suspension components first. If the issue persists, a professional check of the steering system is necessary to ensure driving safety.
