Message	I had my rear end completely apart doing ES poly bushings for subframe, diff and all rear pieces. Put in new Redline 75W-90 diff fluid. Now I have this rubbing/grinding type of noise coming from my rear end even when just spinning it by hand slowly. Here's a youtube video of the sound. This was taken from the drivers side, but it sounds roughly the same from side to side. Currently, including in the video, I have the driveshaft and brakes off, so that should eliminate some things. Everything in the rear is nice and tight. I can't figure out where the noise is coming from. I drove around the block on it this way a couple times before taking everything back off. Really not sure what else to do, the diff was fine before. Ideas?
