RE: drivetrain slip.
did you switch to synthetic gear oil on the diff? synthetic can "creep" around worn seals. Also if you had the rover tilted to that side for an extended time maybe it creeped a bit more than normal on a worn seal.
start with the new seal and drain/refill with 100% synthetic gear oil like mobil1. My RRC has "open" differentials that have no limited-slip clutches -- your probably does too -- in this case no posi-trac additive is required. usually the limited slip is controlled via the ABS system and brakes on a rover. that is the case on my 1993 -- and probably is the case on 01 - but double check with DiscoMike on that one.
when you remove the axle shaft, feel the area of shaft that contacts the seal. If there is a rough groove in the shaft there you should consider (1) polishing the surface smooth and checking that the seal still "seals" the shaft (2) getting a collar for the seal area (3) replacing the axle shaft (4) welding and grinding the rough area smooth. a rough surface there will screw up the new seal quickly. As long as the area contacting the seal is smooth, round, and the correct size you should be good. Excessive drivetrain vibration with "ream out" a seal and cause leaks. Fix the vibration and replace the seal. I installed bent rims on a VW jetta once that trashed my axle output seals in less than 300 miles and lost lots of fluid. changed the rims out and the seal and life was as good as it gets in a Jetta again.
Is the tire on that corner unusally cupped? Is the shock on that corner bad? fix vibration and the seal.
When you say HUB -- are you talking about the front hub? is your 01 independent suspension on the rear axle (2 mini-driveshafts going to each wheel and not a solid axle)?
How many miles on this one?
