What is a wheel hub assembly?
The wheel hub assembly is made up of the bearings, hub, rotor, seal, and drive shaft. These work together to keep your wheels attached to the vehicle and allow the wheels to turn easily so you can steer.
Your car’s anti-lock braking system (ABS) and traction control system (TCS) also rely on the wheel hub assembly. The assemblies house the wheel speed sensors that communicate with these safety systems.
