There are several common methods to repair the damaged wheel hub: 1. The edge of the hub is scratched and damaged. This situation is more common, and it is easy to scratch the edge when driving against the curb. In this case, you only need a special repair stick to repair it. 2. The wheel hub flange is cracked and damaged. When the car is driving, the hub is accidentally hit by a hard object, which will cause the edge of the hub to break. Usually, the hub can be repaired by a special aluminum welding machine for the hub, and then the hub can be refurbished and reshaped after welding. 3. Hub edge clearance. When the hub is hit by a stone or a hard object, the edge of the hub will be knocked out of a gap. Then, you need to fill this gap with a special hub. Because of strong adhesion, it is not easy to peel off after repair.
