Buick equipped the 2003 model year Regal with rear wheel bearings integrated into the wheel hubs on both the rear drum and rear disc brake systems. The rear wheel bearings are not serviceable as a separate component. If the wheel bearings require replacement, replace the bearings as a unit with the hub assembly.
