HOWO traveling in the direction of deviation of the more common, if not eliminate the fault, more dangerous, generally by doing wheel alignment solve. If you still can not be eliminated, it may be other causes, you must first find the cause in order to completely remove the fault.
Common reasons are the following:
1 a tire brake return bad separation will result in the direction of deviation. This corresponds to the side of the wheel is always part of the brake is applied, driving up the vehicle will inevitably deviation.
2.The frame overall deformation. Both sides of the wheelbase difference is too large, exceeds the maximum allowable range, through the tape measure to measure, such as out of range must be corrected using a calibration station.
3 there is a result in the direction of the deviation of the reasons is to install tire (unilateral tires), did not pay attention to the pattern direction (not in the same direction), take a look at your tires is not the installation did not notice the pattern direction, if just change over on the right.
4.Front shock absorber spring the deformation both sides of the buffer inconsistent. You can push or demolished comparison to judge the good and bad of the shock absorber spring.
5 front shock absorber failure. After the failure of the front shock absorber hanging two vehicles traveling one high and one low, discontinuity, causing deviation. Can detect the absorption of the shock absorber by special damping tester to determine the shock absorber is good or bad, timely repair.
6 vehicle chassis parts wear too much normal gap exists. Steering Spurstangenkopf support arm pouches, stabilizer bar pouches common gap is is easy too large parts, carefully check should lift vehicle.
7 on both sides of the tire tread pattern is a deep one shallow is not as high. The best is the whole car to use the same type of tire, at least two of the front axle and the rear axle of the tire must be the same, and the tread depth must be the same, more than the wear limit must be replaced. 8 on both sides of the tire pressure range. Tire pressure ranging from tire will become sample sizes, scrolling up will inevitably deviation
