The way my father taught me (who was taught by his father) is first clean the bearings using solvent and a small brush to get out any fine particles of dirt or grime. Then dry the bearings with a rag and air. Take a generous amount of good wheel bearing grease and put it in the palm of your hand. Push the outer diameter of the bearing into the grease and with a wiping motion move it against the pad of your palm and push firmly. Turn the bearing slightly and repeat. Keep doing this until the whole bearing is packed. That’s all the grease we use; none in the race and none anywhere else. The bearings are designed to be lubricated, not “floating” like you find with your rear bearings where they ride in oil. If we don’t get 250,000 miles out of a set of bearings we consider it premature failure.
