Clean everything, apply a thin bead of grease around the hub bearing race, start putting balls in, there should be enough balls that there's no real space between them, one ball too few and you could have problems.. once all the balls are in the hub stuck to the grease, apply more grease to the axle nut bearing race and install the axle.. Tighten untill finger tight, lock the lock nuts down and check for over-tight/too loose.. if too tight back off one of the cones
Ya but theres two sides and the bearing keep falling in the axel hole then i need to flip the rim to put bearing in on the other side then the other ones fall out to i need like a spacer to tempers let hold em in?
