Mitsubishi Pick-ups and Montero 1983-1995 Repair Guide

Wheel Bearings



The following procedures are for the non-driven wheels on 2wd vehicles only. Since all the wheels on 4wd vehicles are driven, periodic greasing of the bearings is not necessary. For wheel bearing procedures on 4wd vehicles, please refer to Suspension & Steering .

The wheel bearings of the non-driven wheels on trucks, the front wheels on 2-wheel drive Pick-ups, should be repacked with Multipurpose Grease NLGI Grade #2 E.P. or equivalent grease every 2 years or 30,000 miles (48,000 km). The best way to accomplish this is to combine the repacking operation with brake repairs. In other words, if brake linings require attention, always repack the wheel bearings associated with the repair at the same time to avoid repeating the operation at the specified interval. Of course, if brake linings last longer than this interval, wheel bearings should be repacked as a discrete operation.

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 with a clean cloth or plastic bag.
Use clean rags to wipe bearings.
Keep the bearings in oil-proof paper or plastic 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:

Do not work in dirty surroundings.
Do not use dirty, chipped or damaged tools.
Try not to work on wooden work benches or use
