"I always run to the right in my car, do a few positioning or run off, how should we solve?" experts say, driving in the middle of the car is a relatively common problem. Four wheel positioning misalignment. In most cases, four rounds of positioning can be done, but if the four round of positioning is still unable to solve, this must be caused by other reasons. The tire patterns on both sides are different or patterns are not as high as deep. It is best to use the same type of tires all over the car. The minimum two tires at the minimum front axle and rear axle must be the same, and the pattern depth must be the same, and the wear limit must be replaced. The air pressure on both sides of the tires is unequal. Different tire pressure will make the tyre different in size, and it will run away when it rolls up. The front shock absorber spring deformation is inconsistent on both sides of the buffer. The spring of the shock absorber can be judged by comparison after pressing or disassembling. The front shock absorber failed. When the front shock absorber fails, it will be suspended two high and low in the vehicle running, and the force will be uneven, leading to deviation. The absorbance of shock absorbers can be detected by special shock absorbers, and the quality of shock absorbers can be judged. Abnormal wear occurs when vehicle chassis parts wear too much. The steering rod ball head, the supporting arm rubber sleeve, the stabilizer bar rubber sleeve and so on are common parts with too easy clearance. The lifting vehicles should be carefully examined. The defective return of a wheel brake is incomplete. This is equivalent to a partial braking of the wheels on the side, and driving will inevitably run away. During inspection, the temperature of the hub can be felt, for example, a wheel exceeds a number of other wheels, indicating that the wheel's brake is not in good position. The overall deformation of the frame. The wheelbase difference between both sides is too large, exceeding the maximum allowable range. It can be measured by tape measure. If it is out of range, it must be calibrated with the calibration table.
