This x2!
If the diff were making all the racket, I'd expect you to find metallic oil or metallic filings in the oil. Unless the oil in the diff were JUST changed, clean oil would suggest the noise is coming from the driveline rather than the diff. A bad U-joint can make a heck of a racket and vibration.
