Can't be repaired, can't, repeated knocking will lead to metal fatigue, durable. If it's an aluminum rim, it's probably 150-200 yuan to change it. Special models or some more expensive models will be more expensive.

If it's a spoke wheel, it only costs tens of dollars to change the hub inside, but it costs tens of dollars to re-spoke this kind of wheel. If the spoke wheel is replaced with an inner hub, an outer rim and spokes, the total price will be around 200 yuan.

Important role:

As the internal supporting part of the tire, the wheel hub is often very hard. But once the hub is damaged, it will bear severe friction. If it is not repaired, it may cause serious damage to the alloy part and even affect the stability of the vehicle. So it needs to be repaired in this case.
