Trey,

About a month back I posted about hearing some strange clanking noise. Well.. I had the rear of the car up in the air and was changing the differential fluid. I noticed if I rotated the rear tires back and forth quickly I could duplicate that noise. It almost sounded like bad ujoints or something.. I really couldn't tell. Sounded maybe from the spider gear or even from behind it.. was really weird.. it was more like a shaking metal noise.. hard to say what it really sounded like. I checked all the teeth on every gear in the rear.. they all looked flawless.

Any ideas?.. TIA.
