Jeep Wagoneer/Commando/Cherokee 1984-1998

Wheel Bearings



This procedure only applies to 1984-92 Jeep vehicles. The 1993-98 Jeep vehicles are equipped with wheel bearings that are an integral component of the wheel hub and therefore, cannot be serviced separately. If the wheel bearings on these models need servicing, the wheel hub and bearing assembly must be replaced.

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.

  1. Remove the wheel bearing(s) from the vehicle.
  3. If the old parts are retained, thoroughly clean them in a safe solvent and allow them to dry on a clean towel. Never spin them dry with compressed air.
  5. Pack the inside of the hub with EP wheel bearing grease. Add grease to the hub until it is flush with the inside diameter of the bearing cup.
  7. Pack the bearing with the same grease. A needle-shaped wheel bearing packer is best for this operation. If one is not available, place a large amount of grease in the palm of your hand and slide the edge of the bearing cage through the grease to pick up as much as possible, then work the grease in as best you can with your fingers.

  5. Coat the race with wheel bearing grease and place the bearing in the bore.
