- Remove the driveshaft.
- Remove the retracting spring clevis pin and the spring clip.
- Remove the hub locknut, the nut and washer from the transfer case output shaft.
- Using a puller, remove the brake drum and companion flange.
- Remove the retracting springs and shoes from the backing plate.
- Clean all parts with a safe solvent.
- Installation is the reverse of removal. Replace any weak springs and clean the adjuster threads. Coat the threads with a light film of oil. It will be necessary to back off the adjusting screw wheels to allow drum installation.
- Adjust the brake.
Make sure that the brake operating handle or foot pedal is fully released. Check the operating linkage and the cable to make sure that they don't bind. If necessary, free the cable and lubricate it. Rotate the brake drum until one pair of the three sets of holes are over the shoe adjusting screw wheels in the brake drum as a fulcrum for the brake adjusting tool or a screwdriver. Rotate each notched adjusting screw by moving the handle of the tool away from the center of the driveshaft until the shoes are snug against the drum. Back off seven notches on the adjusting screw wheels to secure the proper running clearance between the shoes and the drum.
The brake operating lever position must be properly set. The setting point is a measurement between the lever and the brake backing plate at the closest point between the two. The proper gap is 3 / 32 ". Rotate the ball nut to adjust the clearance.
