The Wheel Hub Assembly Kit includes the wheel hub and its associated components. The wheel hub assembly is mounted between the brake discs or drums and the drive axle. The automobile's wheels are bolted to the wheel hub assembly on the disc side.

A wheel bearing is a crucial part of the wheel assembly that connects the wheel and the axle. It is a set of steel balls (ball bearings) or tapers (tapered bearings), held together by a metal ring. It enables the wheel to rotate smoothly with a minimum of friction.
