Stones on the road do the most damage to aluminum alloy wheels, which are the safety parts in the car. Therefore, the aluminum alloy hub can not be repaired by repair, because the aluminum alloy is brittle, and the recessed part may have been damaged (such as cracks), and forced reset may cause the hub to break. In order to avoid safety accidents caused by wheel hub breakage, it is recommended to replace the wheel hub with a new one for safety reasons.
