The vehicle deviation is a common problem, in most cases, the four wheel positioning to solve the problem. But sometimes do four wheel positioning is not good, it must be caused by otherreasons, must find out reason, fault can be completely cured of deviation. In addition to the fourround of misregistration, the main causes of deviation may also have:

1 sides of the tire tread pattern is not the same as a pattern or a deep shallow not high. The best is the whole car use the same type of tires, two tires at least the front axle and rear axlemust be the same, and tread depth must be the same, more than wear limit must be replaced. In addition, both sides of the tire pressure range. Tire pressure in the tire becomes unequal size,rolling up bound deviation.

2 before the shock absorber invalidation. After the failure of the shock absorber in the vehiclesuspension of two high and one low, uneven stress, leading to deviation. Through the specialvibration test instrument to detect the absorption of shock absorber, shock absorber is good or bad judgment, if no conditions can be used to remove the stretching method of judgment.

3 vehicle chassis parts excessive wear is not normal clearance. The steering rod ball head, armrubber sleeve, the rubber sleeve stabilizer bar is a common part of the gap is too large and easy, lift the vehicle should be carefully examined.

Thus, although the four wheel positioning can bring good protection to our car, but safe driving,four wheel positioning is not a panacea. Four wheel alignment in the repair factory is morecircumspect, a lot of repair plant in order to reduce the workload, four wheel positioning didmumble. For example, the normal four wheel positioning need to adjust the 8 indexes, somerepair factory only adjust the several indicators including. Insiders remind owners, in the car to replace the new tire or collision repair, or partial wear of tire before and after unilateral, drivingwheel, heavy floating or shaking, in the car to the left or right deviation of the straight line, you need to do four wheel positioning. If it does not, for maintenance purposes, also suggested that the new car in the car, driving after three months of every year or ten thousand Km for a four round of positioning. Four wheel alignment, can have a look to the owners of the best detectioncomputer, reference data after adjustment for the four round of data should be above (or factory data line). If there are other faults, or, the car had just finished the four round of this location, we must find the reason from other aspects.
