Man.. With only 44,000 miles you should ask about a good faith warranty on the rear end.

Maybe a "bearing let go" is dealer code for not topping off the differental when they serviced it

he did say in another thread that it needed a pinion seal at 37,000mi.it probably ran low for awhile and did some damage.these trucks dont hold a lot of oil in the diffs. what looks like a very minor leak could empty your diff in a couple months or less if let go.

Yeah, that was my guess because of the "humming" sound. Hey good thing he's got a good warranty!

well i just found out from the dealer that the rear end in my trucks has been worked on previously and when the tore the rear end apart and put it back together they never put a seal in it which caused my rear end to go
