Details of the rear wheel bearing and oil seal are shown in an exploded view. To remove the oil seal and bearing, remove the rear axle nut, raise the car and take off the brake drum. The hand brake should be disengaged to make this easy. Remove the retaining screws from the cover and take off the cover along with the oil seal. Remove brake line, and take off back plate, outer spacer, gasket between bearing and spacer, washer, and cover gasket. Remove the rear wheel bearing and inner spacer.

Installation is the reverse of the foregoing, but in addition, certain other steps should be taken. The condition of the bearing should be examined, and the bearing replaced if necessary. Replace the two sealing rings. If the oil seal is damaged or uneven, it should also be replaced. When installing a new oil seal, coat it with oil and press it into the bearing cover. The outer spacer should be examined for wear, replaced if scored or cracked, and lightly coated with oil when installed. Clean the oil hole in the cover and replace cover. The splines in the brake drum hub should be inspected and the brake drum replaced if the splines show signs of excessive wear. Tighten the rear axle shaft nut to a torque of 217 ft. lbs., using a new cotter pin and turning nut slightly tighter if necessary to line up holes for cotter pin.

Check the level of lubricant in the transmission and top up if necessary. The oil should be at a level even with the lower edge of the filler hole. Bleed and adjust the brakes.
