First of all, you can be sure that there is no fracture, but there is some deformation. The most likely place is the lower arm of the right suspension and the related ball head. After these places are deformed, four-wheel positioning can find that the data is wrong, but it can't be corrected to the normal value, even if it is corrected by eccentric screws, it can't last long. Therefore, it is necessary to find the deformed parts, repair or replace them, and then do four-wheel positioning to ensure accurate wheel positioning.

In addition, pay attention to whether the hub is deformed after being hit (only the dynamic balance of the hub can be known), and if it is deformed, it must be repaired or replaced. Usually iron wheels are easy to deform, but they are also easy to repair. Aluminum wheel hub is not easy to deform, and it is easy to lose its dynamic balance after scratching, and the deformation is more difficult to repair.
