To remove the oil seal from the end of the axle housing, remove the axle shaft. Then, use a pry tool to remove the oil seal. Apply a film of multi-purpose grease to the oil seal recess and install the new seal evenly with a hammer and seal installation tool. The oil seal should be aligned with the axle housing. Finally, install the axle shaft.

To remove and install a rear hub assembly, first remove the axleshaft and rear wheels, then remove the brake disc and retaining ring/key from the end of the axle housing. Use a special socket to remove the adjusting nut and pull the hub assembly straight off the axle tube. Discard the oil seal and clean and inspect all components for wear or damage. Disassemble the hub further if necessary, then clean and reassemble using new bearing cups and lubricating with wheel bearing grease. To install, place the hub assembly on the axle tube and adjust the bearings by tightening the adjusting nut to 50 ft-lbs, then backing it off and tightening it hand-tight. Install the key and retaining ring, and ensure there is no play in the hub assembly before reinstalling the axleshaft and lowering the vehicle.
