When going back together, remember to properly toque the outer hub nut. Alot of guys forget to do that, thinking that snugged up us all that's needed. It isn't. That outer nut torques to 150-175 ft/lbs. Failure to torque it properly can result in wheel loss. I've seen that happen on a late '70s 3/4 ton that was serviced in the shop I work at (not by me). Same goes for the hubs on the front of a 4x4.
