The reasons are as follows: 1. The difference between left and right tire pressures is large; 2. The left and right shock absorption is damaged; 3. Abnormal four-wheel alignment parameters; 4. The degree of tire wear is inconsistent.

1. The tire pressure difference between left and right is large;

Usually, this happens only when the wheels are nailed or damaged, and the tire pressure difference is large, resulting in uneven driving force of the car body, which will lead to one-sided vehicle and deviation of the direction of the car.

2. The left and right shock absorption is damaged;

When the damping coefficients of the left and right sides of the car are inconsistent, the difference is large, or when the spring of the shock absorber is deformed and one side fails, the suspension will also fluctuate, resulting in the phenomenon of direction deviation.

3. Abnormal four-wheel alignment parameters;

Many car owners adjust the four-wheel alignment parameters irregularly, and their vehicles run under inappropriate parameters for a long time, especially those who often walk on bumpy roads. The four-wheel alignment parameters are very easy to change, and the direction deviation of the car is usually camber. Therefore, when doing four-wheel alignment, we must pay attention to whether the camber angle is normal.

4. The degree of tire wear is inconsistent.

If the tire surface wear degree is different, or the brand patterns of the four tires are different, it will cause deviation, especially if the refurbished tires or new tires are installed. The first 300 kilometers is the running-in period of the tires, so please drive carefully.
