maybe the seals could leak the water in if you were to sit in the water for a long time. maybe a 30 minutes. i have seen water in diffs before but usually guys who tow boats and put the truck too far in at the launch ramp. now there is a switch at the rear diff for the locking rear diff. if that seal were leaking you might not get a oil leak up that high. but that is on the rear on my truck. my front is a open diff not a locker. so no switch in the front.
Yea we never sat in water, maybe 5-10 minutes driving through it. I'm stumped! Vent tubes are dam near brand new looking. The front diff had way more than the rear.
