What Causes Vehicle Direction Deviation?
2 Answers
Here are the reasons why a car may deviate from its direction and the corresponding solutions: 1. Unequal tire pressure, different tread patterns on the two sides or uneven tread depth, suspension system failure, steering system failure, deformation of front shock absorber springs leading to inconsistent buffering on both sides, failure of front shock absorbers, excessive wear of vehicle chassis components causing abnormal gaps, or incomplete separation and poor return of a wheel's brake. 2. Take the vehicle to a professional repair shop for a four-wheel alignment and adjust the steering tie rod by 'screwing in' or 'screwing out' the tie rod base. The steering wheel is a wheel-shaped device used to control the direction of cars, ships, airplanes, etc. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft.
When I drive, my car always pulls to the left. At first, I thought it was due to uneven road surfaces, but later I discovered that uneven tire pressure was the culprit. Asymmetric pressure on both sides naturally causes the car to drag toward the side with lower pressure. Uneven tire wear is also quite common, especially if the front tires aren’t rotated regularly, leading to significant differences in grip. Another issue is improper wheel alignment, such as deviations in camber or toe angles, which can cause persistent pulling. Aging suspension components, like loose shock absorbers or worn ball joints, can also destabilize the wheels. In my experience, brake drag was another factor—one side’s brake was stuck, dragging the car along. On rainy days, temporary pulling might occur due to slippery roads, but it usually resolves once the road dries, so there’s no need to worry. In short, regularly checking tire pressure and wear, along with alignment tests every six months, can prevent these issues. Otherwise, long-term misalignment not only wears tires faster but also increases the risk of accidents.
