Is It Normal for the Rear Wheel Axle of the 2020 Bora to Rust?

[LawsonFitz]

It is normal for the rear wheel axle of the 2020 Bora to rust. This is quite common and considered normal because the brake disc is made of metal and is directly exposed to the air without any protection, leading to oxidation and rust. If the rust on the wheel 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 wheel hub may need to be replaced. Function of Wheel Hub Bearings: Wheel hub bearings are one of the key components of a car. Their main function is to bear the weight and provide precise guidance for the rotation of the wheel hub. This requires them to withstand both axial and radial loads. Materials Used: Traditional automotive wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, greasing, sealing, and adjustment of bearing clearance are all performed on the automobile production line. This structure makes it difficult to assemble in automobile factories, increases costs, reduces reliability, and requires cleaning, greasing, and adjustment of the bearings during maintenance at service points.
