wheel hub bearing and hub assemblies
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.
Front wheel hubs connect the axles, steering knuckles, and the wheels. They are imperative to the steering system because they help support the weight of the vehicle and help turn the wheels. The wheel hub has a fixed part, the mounting flange, that mounts to and turns with the steering knuckle, along with a rotating part that contains the lug bolts and holds the wheel and brake rotor. In the center of the rotating part of the hub is the wheel bearing.
