Rear axle is soaked, need help...

[Chamberpains]

3.5 GALLONS?!?! That is a pile of oil. That only leaves about 1.5 or so gallons in the rear. That is running the power divider, through shaft bearings and input shaft bearings dry. I'd be watching and listening to that rear very closely. Don't be surprised if your doing a swap on it in the near future.
