Does a Rusty Car Axle Need to Be Treated?

[McMicah]

Yes, a rusty car axle needs to be treated. If the rust on the hub center axle is not severe, you can use very fine water sandpaper dipped in water to gently remove the rust spots. After completely cleaning it, apply a layer of primer to ensure the rust does not spread or worsen. If the rust is severe, the hub may need to be replaced. More details are as follows: 1. Function of the hub bearing: The hub bearing is one of the key components of a car. Its main function is to bear weight and provide precise guidance for the rotation of the hub, which requires it to withstand both axial and radial loads. 2. Manufacturing materials: Traditional car wheel bearings are composed of two sets of tapered roller bearings or ball bearings combined. The installation, greasing, sealing, and adjustment of bearing clearance are all performed on the car production line. This structure makes assembly difficult, costly, and less reliable in car manufacturing plants. Additionally, when the car is serviced at a maintenance point, the bearings need to be cleaned, greased, and adjusted.
