How to Check Vehicle Pulling to One Side?
1 Answers
Vehicle pulling to one side can occur in the following two situations: 1. During straight-line driving at a constant speed, the vehicle drifts to one side when the steering wheel is released; 2. The vehicle can maintain a straight path without drifting, but the steering wheel is not centered. The causes of vehicle pulling to one side are as follows: 1. Uneven tire pressure between the upper and lower tires. Different pressures result in inconsistent tire circumferences, causing the vehicle to pull toward the side with lower pressure. If the pulling is significantly due to tire pressure, it can often be detected visually. 2. Incorrect toe alignment. Wheel toe alignment primarily refers to the camber angle of the front wheels. Simply put, proper toe alignment creates a "front narrow, rear wide" trumpet shape for the front wheels. Incorrect toe alignment usually results in a "front wide, rear narrow" shape. This issue is often caused by impacts to the front suspension or excessive gaps in suspension links or ball joints. While the primary solution is a four-wheel alignment, the suspension system must first be in good condition. 3. Brake system malfunction. Although brake-related pulling (mainly from the front brakes) is quite subtle, it should be carefully prevented. The most common brake system issue is the front brake caliper not retracting smoothly, which creates resistance to wheel movement.
