  1. Raise and support the vehicle safely.
  2.  
  3. Remove the rear wheels and tires.
  4.  
  5. Pry the brake drum cap off using a suitable tool.
  6.  
  7. Flatten the lockwasher and loosen the axle nut, then remove the lockwasher, lock plate and brake drum. Remove the brake drum taking care not to drop the outer bearing.
  8.  
  9. Check the condition of the bearing grease. If either the grease appears to be white or if only a small amount of grease remains, remove the bearing from the housing, clean it and pack it with fresh grease.
  10.  
  11. To remove the inner bearing, remove the grease seal using a seal puller or equivalent.
  12.  
  13. Clean the bearings with solvent and let air dry on a shop rag.
  14.  

Do not use compressed air to dry the bearings as damage will result.

  1. Place a ball of grease in the palm of your hand and roll the bearing through the grease. Force the grease through the bearing cage into the rollers. Continue to roll the bearing, adding grease to your hand, until the bearing is completely filled with grease.
  2.  
  3. Install the rear bearing and using a soft faced hammer, install the grease seal. Ensure that the seal is fully seated.
  4.  
  5. Install the drum, outer bearing, lock plate, lockwasher and axle nut in this order on to the spindle. Always use a new lockplate and lockwasher.
  6.  
  7. Tighten the locknut to 36 ft. lbs. (49 Nm) and rotate the drum in both directions to seat the bearings.
  8.  
  9. Loosen the locknut 1 / 8 turn. Tighten the locknut to obtain a starting force of 2-3 lbs. (8-14 N) on all models except Justy; 3-4 lbs. (14-20 N) on Justy. Ensure that there is no free-play in the bearing.
  10.  
  11. Install the brake drum cap, wheel and tire. Tighten lug nuts to 58-72 ft. lbs. (78-98 Nm).
  12.  
  13. Lower the vehicle and test drive.
  14.  

DISC BRAKES
  1. Raise and support the vehicle safely.
  2.  
  3. While holding the rear wheel by hand, try to move it in and out (toward you and away from you) to check bearing free-play.
  4.  
  5. Remove the rear wheel and tire.
  6.  
  7. If bearing free-play exists, attach a dial gauge to the hub and measure the axial free-play.
  8.  
  9. If free-play is greater than 0.0020 in. (0.05mm), disassemble the rear hub and check the bearings.
  10.  
  11. Pry the rotor cap off with a suitable tool.
  12.  
  13. Unlock the axle nut and remove the nut and washer.
  14.  
  15. Remove the rear disc brake assembly from the backing plate and suspend it out of the way using a wire.
  16.  
  17. Remove the disc rotor from the hub, then remove the hub.
  18.  
  19. Inspect the hub bearings for damage and replace the hub assembly as necessary.
  20.  
  21. Install the hub, then, using a new washer and locknut, tighten to 123-152 ft. lbs. (167-206 Nm) and lock into place. Install the rotor cap.
  22.  
  23. Install the disc rotor and rear disc brake assembly.
  24.  
  25. Install the rear wheel and tire. Tighten the lug nuts to 58-72 ft. lbs. (78-98 Nm).
  26.
