Is it necessary to repair the wheel hub deformation?
The hub is a little deformed and needs to be repaired.

The hub is an aluminum alloy profile, and the metal material will be brittle. If it is not repaired or replaced on time after modification, it is very likely that the hub will rupture immediately due to hitting obstacles during driving, which is very dangerous.

The scratches on the wheel hub surface can be repaired, including some scratches and bumps, and they can all leave traces after repair. Simply clean, polish, paint and dry. The strength of steel hub is far less than that of aluminum alloy profile, but it is more malleable, so the cracking of steel hub is very rare. If the hub is cracked and damaged, whether it is deformed or not, it needs to be replaced with a new one.

If it is slightly deformed, you can do a rotor dynamic balance first, and it can still be used if possible. If not, it is recommended to disassemble and replace the hub. If it is severely deformed, whether it is a steel wheel or an aluminum-magnesium alloy wheel, even after being forced to return to normal, its compressive strength and ductility can not meet the requirements, and the possibility of fracture is higher, leaving only obvious safety hazards. It is recommended to remove and replace.

What effect does hub deformation have on the car?

1 First of all, as an indispensable part of the car, the wheel hub bears the main impact and pressure of the car. Therefore, once the automobile hub is deformed, it will affect the reliability of the vehicle and reduce the grip of the automobile wheel.

2. The deformation of the wheel hub will cause the change of the centrifugal force of the wheel, which will increase the control difficulty of the car when walking and cause the car to run unsteadily. Even if driving on a gentle main road, shaking will inevitably occur.

3. After the deformation of the automobile hub, the stress degree of the automobile tire will be different, which will lead to air leakage and shorten the service life of the tire due to the left and right bumps.
