I got into a bit of water this afternoon. Only the passenger side. Over the front tire and 2/3 up the rear (again, passenger side and I'm running 235/75/15s which sit at a real-world 27 3/4"). I pulled both diff covers and drained/refilled them--all looked great. So, the question is, do I still need to pull out the axles to check the tubes? Also, as a sideline question, I unscrewed the tranny drain plug, and the fluid looked normal so I hurried up and screwed it back in--do I need to investigate that further?
