1 Auto Shop - Wheel Bearing Hub

Your wheel bearings and hubs are important parts of your vehicle's steering, suspension, and braking systems. Most modern vehicles use a one-piece hub assembly that incorporates the hub, wheel bearing, ABS wheel speed sensor, and mounting flange. ** Though you may never even see it, a wheel hub bearing unit is an important part of a car's wheel assembly, enabling wheels to turn freely and playing a crucial role in the safety and handling characteristics of a vehicle. ** The WHA is located between the brake drums or discs and the drive axle. A wheel is bolted on it. Depending on the construction, the end of hub comes equipped with the splined teeth. They mate the teeth on the axle shaft. The axle hub spins along with the wheels bolted to it and provide the power to the wheels in order to rotate.
