I have said for years, if you balance your trailer wheels and keep the spindle nut correctly tightened you won't loose your Bearing Buddies. Well it has come to haunt me. Lost a "BB" this am. With wheel off the ground I can shake the wheel a bit. Just more than I would expect. One slot in the nut is too tight, back off one and it is loose enough to question. Is there such a thing as various thickness spindle washers or more slots to the nut. P.S All bearings are next to new..Thanks
