wheel hub assembly

While you can drive with a broken wheel bearing, you really shouldn't be.

On each wheel, you’ll find the wheel hub assembly between the drive axle and the brake drums or discs. On the brake disc side, the wheel is attached to the bolts of the wheel hub assembly. While on the side of the drive axle, the hub assembly is mounted to the steering knuckle either as a bolt-on or press-in assembly.

It is hard to imagine a car without wheels. Although the engine and transmission are key components of any vehicle transmission system, without wheels, the vehicle cannot roll from one place to another. But in order to have a functional, rolling wheel, you first need a viable hub assembly. Without a viable wheel hub assembly (WHA), the wheels of the vehicle will not function properly, which limits the potential of the vehicle itself.
