This assembly consists of the hub, the hub bearings, and the front hub assembly. The hub is the rotating part of wheels located at its center. It helps keep the wheels in proper alignment to establish better handling and steering. On the other hand, the hub bearings support the entire assembly to keep it in place.
Inside the wheel hubs are either roller or ball bearings that carry the vehicle's weight. On RWD vehicles with solid axles, the rear wheel bearings are mounted on the axles. The front wheel bearings on older rear-wheel drive cars and trucks usually require "repacking" (regressing) every two years or 24,000 miles. The wheel bearings on most new vehicles are sealed and do not require any maintenance. A bad wheel bearing will typically make grinding, whining or squealing noises, and you can often feel the looseness or roughness if you raise the suspension and rotate the wheel by hand. Worn wheel bearings should be replaced, because failure may cause the wheel to come off the vehicle.
