Welcome to CF. Sounds like bad bearings. Since the pinion seal is leaking, test for excess play of pinion bearings. Block the wheels/apply the e-brake & put it in neutral. See if you can move the driveshaft/yoke assembly up & down/sideways/in & out at all. It shouldn't have any play. This doesn't prove they're good though.
It could be the pinion bearings or the carrier bearings IMO.
