Ok. I have already pulled the fuse for all wheel drive and that cut out some of the drive line noise but I still have a stumper I can't figure out. I do know the driver rear axle seal does leak and after long trips I can smell s little gear oil at that corner. It is checked frequently but I haven't had it to long so idk what was done before.... Also after driving a little it has a weird vibe and growl type noise. And by the feel of it sometimes its out the back and sometimes I just can't tell. But how do I check rear bearings? And what else should i look for?
