Pontiac 7470503 New Old Stock Rear Wheel Hub Assembly

The bearings should be repacked every 30,000 miles (48,000 km) and adjusted properly. It is recommended to repack the front wheel bearings during brake repair service. Repack the bearings when removing the rotors for brake pad replacement. Properly adjusted bearings should have a slightly loose feeling and should never be preloaded. If the bearings are too loose, clean and inspect them before repacking and adjusting. To adjust the bearings, raise the vehicle, remove the wheel cover and dust cap, remove the cotter pin and spindle nut, tighten the nut as the wheel spins, back off the nut, and insert the cotter pin. For removal and installation, raise and support the vehicle, remove the wheel and tire assemblies, remove the hub/disc assembly, remove the outer and inner bearing assemblies, wash and inspect the parts, install a new race, pack the bearing with grease, install a new grease seal, install the hub or hub/rotor assembly, install the rotor, install the wheel and adjust the wheel bearing, and install the grease cap. When repacking the bearings, clean and inspect them, fill the bearing cone and roller assemblies with grease, and reassemble and adjust the bearings.
