BEARING LUBRICATION - GREASE
Bearing grease should be replaced every 12,000 miles or 12 months, whichever comes
first. Remove all old grease from wheel hub and bearings first. Bearings should be
packed by machine if possible. Packing bearings by machine is preferable; however,
packing by hand is a viable alternative.
Follow these procedures to repack bearings by hand:
1. Place grease into the palm of your hand (Fig. 1).
2. Press widest end of bearing into the outer edge of the grease pile, forcing grease
into the inner area of the bearing between two adjacent rollers (Fig. 2).
3. Repeat this process while turning bearing from roller to roller until all rollers are
coated.
4. Apply a light coat of grease into the bearing cup surface.
5. Reassemble bearing into cup.
