Although the axle shaft is easily removed using common hand tools, special tools are required if the bearings are also to be serviced.
CAUTION Brake shoes may contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.
It is recommended, when the axle shaft is removed, to replace the oil seal.
When installing the axle shaft(s), be careful not to cut the oil seal lips.
When adding oil to the rear axle, be aware that some locking differentials require the use of a special gear lubricant additive.
Make sure the vehicle is level before attempting to add fluid to the rear axle or an incorrect fluid level will result.
