My rig has a fairly bad oil leak from either the rear main or the pan. Perhaps even an oil gallery plug on the rt side of the rear block. It's nearly impossible to tell which without R&R of the drivetrain. Q: Any idea how much each of the transfer case and transmission weigh? I'm debating whether I should rent a tranny jack. I'm not a big fan of crushed ribs. Q: Anyone out there found a nice scope for investigating such pesky leaks?
