Theoretically, it can be repaired. The principle of repair should be to heat the damaged part first and then reshape it. Reach the state before destruction. But the cost is very high, even higher than replacing a new hub, so this method is basically unnecessary.

There is another method that is most commonly used. Sheet metal workers often do it: smash the injured position of the hub back and forth into a rough circle with a hammer, of course, it can't be like a new one, and then polish the corners with putty to repair the appearance. Finally paint. After this repair, the appearance is basically no problem, but it is recommended to replace the wheel hub as much as possible.

Because after all, after the injury, the original wheel hub was repaired by external force, and the aluminum alloy at the injured position was already very fragile. If it is hit again or subjected to external force, it is easy to cause the wheel hub to break and cause an accident. If you really don't want to replace it and use it after repair, don't put the repaired hub on the front wheel!
