To replace the rear hub/bearing assembly, begin by loosening the wheel lug nuts and raising the vehicle securely on jackstands. Remove the wheel and the brake drum. Remove the rear hub/bearing dust cap with a hammer and chisel, and then remove the retaining nut. Discard it and pull the assembly off the rear spindle. To begin installing, use a new retaining nut. Install the wheel. Lower the vehicle and tighten the lug nuts.
