I'm getting a loud, roaring rear end sound and vibrations especially around 55mph. At first I thought it was my tires were going bad. I tried a couple of sets and the sound was still there. So I thought it was one of my wheel bearings so I replaced one of them. Sound still there. Then I rememered I changed my diff fluid with 85w-140 gear oil (really thick stuff). I'm thinking that has something to do with it. I'm going to switch it out with 80w-90 but any does anything think that would be the problem? Previous owner of my car installed a vlsd (i think it's a vlsd and i'm assuming the internals weren't swapped out for an aftermarket lsd).
