REMOVAL & INSTALLATION
- Raise and safely support the vehicle.
- Remove the wheel and tire assembly and remove the grease cap.
- Carefully raise the staked portion of the attaching nut using a suitable chisel.
- Remove and discard the hub nut. Remove the brake drum/bearing assembly.
- Position the brake drum/bearing assembly on the spindle and install a new locknut. Tighten the locknut to 73-131 ft. lbs. (98-178 Nm).
- Stake the attaching nut using a suitable chisel with a rounded cutting edge.
- Install the grease cap and the wheel and tire assembly. Tighten the lug nuts to 65-87 ft. lbs. (88-118 Nm).
- Lower the vehicle.
Clean all grease, brake fluid, and other contaminants from the brake drum using brake cleaner. Visually check the drum for scoring, cracks, or other damage.
Measure the diameter of the drum using a suitable micrometer. Measure the diameter at various points around the circumference of the drum and at the bottom of the deepest groove, to determine if the drum can be machined or must be replaced.
If the braking surface diameter is worn in excess of the maximum diameter, 9.06 in. (230.1mm), the drum must be replaced.
