REMOVAL, REPACKING, & INSTALLATION
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 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 likely 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.
For information on wheel bearing removal and installation, refer to
Remove the wheel bearing.
Clean all parts in a non-flammable solvent and let them air dry.
Only use lint-free rags to dry the bearings. NEVER spin-dry a bearing with compressed air, as this will damage the rollers.
Check for excessive wear and damage. Replace the bearing as necessary.
Packing wheel bearings with grease is best accomplished by using a wheel bearing packer (available at most automotive parts stores).

If a wheel bearing packer is not available, the bearings may be packed by hand.
Place a "healthy" glob of grease in the palm of one hand.
Force the edge of the bearing into the grease so that the grease fills the space between the rollers and the bearing cage.
Keep rotating the bearing while continuing to push the grease through.
Continue until the grease is forced out the other side of the bearing.
Place the packed bearing on a clean surface and cover it until it is time for installation.
Install the wheel bearing.
