I have a 95 with the 10 bolt one wheel wonder, sucks i know anywho, there is a wobbling noise that is coming off the rear end, sounded like a miscut drum or something but i got those checked and they are clean, thought mabye tire noise, but when i replaced those the wobbling persisted. any ideas of what this could be? thanks.

Just throwing an idea outthere, could it be your ring and pinion not meshing together?? I don't really know for sure just guessing.
