Before handling the bearings, there are a few things that you should remember to do and not to do:

Remember to DO the following:

Remove all outside dirt from the housing before exposing the bearing.

Treat a used bearing as gently as you would a new one.

Work with clean tools in clean surroundings.

Use clean, dry canvas gloves, or at least clean, dry hands.

Clean solvents and flushing fluids are a must.

Use clean paper when laying out the bearings to dry.

Protect disassembled bearings from rust and dirt. Cover them up.

Use clean rags to wipe bearings.

Keep the bearings in oil-proof paper when they are to be stored or are not in use.

Clean the inside of the housing before replacing the bearing.

Do NOT do the following:

Don't work in dirty surroundings.

Don't use dirty, chipped or damaged tools.

Try not to work on wooden work benches or use wooden mallets.

Don't handle bearings with dirty or moist hands.

Do not use gasoline for cleaning; use a safe solvent.

Do not spin-dry bearings with compressed air; they will be damaged.

Do not spin dirty bearings.

Avoid using cotton waste or dirty cloths to wipe bearings.

Try not to scratch or nick bearing surfaces.

Do not allow the bearing to come in contact with dirt or rust at any time.

The following procedure pertains to 1982-86 2WD vehicles only. These vehicles have serviceable rear wheel bearings. 1987-96 and 4WD vehicles have pressed-in wheel bearings, which are covered in Section 8.

  1. Raise the rear of the vehicle and safely support it on jackstands.
  3. Remove the rear wheels.
  5. Work off the center (dust) cap by using a thin tool. If necessary, tap around it with a soft hammer while removing.
  7. Use a pair of pliers to straighten, then pull out the cotter pin. Take off the adjusting cap and unfasten the wheel bearing locknut.

During removal, be careful to avoid damaging the O-ring in the dust cap.

  1. Remove the drum with the bearing inside. To remove the wheel bearing races, knock them out of the brake drum using a suitable brass punch.

On Pulsar models, a circular clip holds the inner wheel bearing in the brake hub.

  1. Remove the bearing from the drum using a long brass drift pin or equivalent.
  3. Remove the old grease from the bearing. Thoroughly clean the bearing before applying new grease.

To install:
  1. Use a cone shaped bearing packer to thoroughly grease the wheel bearing. If such a bearing packer is not available, fill the palm of your hand with fresh grease and, using your other hand, move the bearing through the grease. Be sure to coat the entire circumference with grease, and thoroughly work it between the rollers.
  3. Install the inner bearing assembly in the brake drum, then install the drum on the vehicle.

The rear wheel bearings must be adjusted after installation; if a one-piece bearing is used, torque the wheel bearing locknut.

  1. Install the outer bearing assembly, wheel bearing locknut, adjusting cap and a new cotter pin.
  3. Install the center cap and the wheel assembly.
  5. Remove the jackstands, then lower the vehicle.


See Figures 1, 2, 3 and 4

  1. Raise the rear of the vehicle and safely support it on jackstands.
  3. Remove the wheel/tire assembly.
  5. Remove the bearing dust cap with a pair of channel locks pliers.
  7. Remove the cotter pin and retaining nut cap (if equipped); dispose of the cotter pin.
  9. Tighten the wheel bearing nut to 29-33 ft. lbs. (39-45 Nm).
  11. Rotate the drum back and forth a few revolutions to snug down the bearing.
  13. After turning the wheel, recheck the torque of the nut, then loosen it 90° from its position.
  15. Install the retaining nut cap (if equipped). Align the cotter pin holes in the nut or nut cap with the hole in the spindle by turning the nut clockwise. Do not loosen it. Tighten the nut no more than 15° to align the holes.
  17. Install the cotter pin and bend up its ends, then install the dust cap.
  19. Install the wheel/tire assembly.
  21. Remove the jackstands, then lower the vehicle.
