Baoqi Technology answers for you that the wheel hub can be repaired, but if you know the damage degree of your wheel hub, such as the wheel hub is broken, it is not recommended to repair it. There is no safety factor. If there is a big gap in the hub, maintenance is not recommended. If the gap is too big, it is best not to exceed the thumb width. Also, if the hub surface is yellow and oxidized, it can be refurbished. Renovation is only to polish off the oxidized or corroded part of the wheel hub surface and then spray it professionally.
