Anyone service/replace/re-pack wheel bearings on a 4wd 89-94 pickup with ADD. I'm replacing my driveshafts and figured I'd go the whole nine while the hubs are somewhat taken apart. Did a search but bubkis. Already have new races and oil seals as per FSM but have no idea how hard it's going to be to set new seals and races. Just looking for some hand-holding from a mud member who's done this more times than he can count.
