Raise and suitably support the vehicle.
Mark the relationship of the wheel to the wheel studs in the bearing flange.
Remove the wheel and the tire.
Mark the relationship of the drum to the wheel studs in the bearing flange.
Notice: Do not pry against the splash shield which surrounds the backing plate in an attempt to free the drum. This will bend the splash shield.
Remove the brake drum. If the drum is difficult to remove, use the following procedure: 5.1. Make sure the parking brake is released.
5.2. Back off the parking brake cable adjustment.
5.3. Use a hammer and a small metal punch to bend in the backing plate knockout slug to provide access to the park brake lever.
5.4. Insert the metal punch or a screwdriver through the hole and press in to push the park brake lever off its stop. This lets the shoe and linings retract slightly.
5.5. Apply a small amount of penetrating oil around the drum pilot hole.
Important: After the drum has been removed from the vehicle, be sure to remove the knockout slug, using pliers or vise grips. Then insert a rubber access hole plug (service part) into the hole to prevent dirt or contamination from entering the drum brake assembly.
Before installing brake drum and wheel, adjust the following items: The service brakes. Refer to Drum Brake Adjustment.
