If the hub is found to have scratches, the owner can repair them according to the size and depth of the scratches. If the scar is small or does not cause damage to the inner side of the hub, the owner can use paint thinner for simple repair, as long as the paint thinner is wiped near the scratch to remove dirt. But if the scratch is too deep, then the owner will drive the car to the repair shop for maintenance.
If the wheel hub is deformed and fractured, we can adopt different repair methods according to the different degrees of deformation and fracture. When the wheel hub is slightly deformed and broken and can still be used, we can repair the wheel hub by plastic welding.
However, if the wheel hub is severely deformed and broken, the tire will jump when it is put on the balance instrument for testing. At this time, the tire can no longer be used and can only be replaced with a new wheel hub.

The hub is a cylindrical metal part, the center of which is mounted on the shaft and supported by the inner contour of the tire. Also called rims, rims, wheels and tire bells. There are many kinds of wheels according to their diameters, widths, molding methods and materials.
In the past, the hub bearings of automobiles were mostly paired with single row tapered rollers or ball bearings. With the development of science and technology, automobile hub units have been widely used in automobiles. At present, it is the hub bearing unit that matches the anti-lock braking system. The hub unit is designed with an inner flange and an outer flange. The inner flange is fixed on the transmission shaft by bolts, and the outer flange installs the whole bearing together.
