Follow Terry's advice, DON'T loosen the nut more than 1 castellation! Tapered roller bearings are meant to run under a slight pre-load. The pre-load happens when the hub heats up and expands while driving, so don't over tighten, but no looseness either. I set mine using water-pump pliers, tighten firmly (not jack-the-bear-tight) while spinning the wheel, and back off to the first hole. No need to fill the cavity between the bearings with grease either, it doesn't flow out to the bearings when driving. Pack the bearings so they bearing are completely filled with grease, put a dab on the outside of the bearing, and adjust.
