Eight reasons for car running deviation or uneven air pressure on both sides
  • Automotive

Self driving tour came back and found that the car always deviated from the right in running, and made several positioning or deviation, how should we solve it? Experts say running deviation is a common problem. There are usually some reasons: the four wheel alignment is wrong. In most cases, deviation can be solved by making four rounds of positioning, but if four rounds of positioning are still unable to solve, this must be caused by other reasons. The sides of the tires are different in pattern or pattern. 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 tyre pressure will make the tyre different in size and drive away. The front shock absorber spring on both sides of the deformation buffer is not consistent. 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. Shock absorbers can be detected by special shock absorbers to determine the quality of shock absorbers. If unconditionally disassembled, it can be judged by stretching. Abnormal wear occurs when vehicle chassis parts wear too much. The steering rod ball head, supporting arm rubber sleeve, stabilizer rod rubber sleeve and so on are easy to appear parts with excessive clearance, and should be carefully checked after lifting the vehicle. 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 to exceed the maximum allowable range. It can be checked by measuring the size. If it is out of range, it must be calibrated with the calibration table.
