Diff fluid was changed very recently, no change. I checked before I dumped it and it was full, and just a little material on the magnet. Trans was changed at the same time. Cv's visually are untorn and no evidence of any grease anywhere around them. I can't see anything loose. I am going to start removing all the cat and exhaust heat shields to see if it might be one of them. It almost sounds like a resonance.
