Rear Wheel Bearings



Sodium-based grease is not compatible with lithium-based grease. Read the package labels and be careful not to mix the two types. If there is any doubt as to the type of grease used, completely clean the old grease from the bearing and hub before replacing.

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 rear wheel bearings should be inspected and lubricated whenever the rear brakes are serviced or at least every 30,000 miles. Repack the bearings with high temperature multi-purpose grease.

Check the lubricant to see if it is contaminated. If it contains dirt or has a milky appearance indicating the presence of water, the bearings should be cleaned and repacked.

Clean the bearings in kerosene, mineral spirits or other suitable cleaning fluid. Do not dry them by spinning the bearings. Allow them to air dry.

  1. Raise and support the vehicle with the rear wheels off the floor.
  3. Remove the wheel grease cap, cotter pin, nut-lock and bearing adjusting nut.
  5. Remove the thrust washer and bearing.
  7. Remove the drum from the spindle.
  9. Thoroughly clean the old lubricant from the bearings and hub cavity. Inspect the bearing rollers for pitting or other signs of wear. Light discoloration is normal.

To install:
  1. Repack the bearings with high temperature multi-purpose EP grease and add a small amount of new grease to the hub cavity. Be sure to force the lubricant between all rollers in the bearing.
  3. Install the drum on the spindle after coating the polished spindle surfaces with wheel bearing lubricant.
  5. Install the outer bearing cone, thrust washer and adjusting nut.
  7. Tighten the adjusting nut to 20-25 ft. lbs. (27-34 Nm) while rotating the wheel.
  9. Back off the adjusting nut to completely release the preload from the bearing.
  11. Tighten the adjusting nut finger-tight.
  13. Position the nut-lock with one pair of slots in line with the cotter pin hole. Install the cotter pin.
