A few days ago I noticed what sounded like a tin can being dragged randomly from my 04 Yukon XL. It was only ever so often. So I got under it to make sure it wasn't an exhaust heat shield or something. Then yesterday as I was backing out of the driveway and turning there were 3 large bangs from the rear end... I had to get to appointment so I drove it anyway and took it straight to the shop after the appointment. Driving over it was making some noise, but coming home it wasn't at all. The shop said the old diff oil was really bad, and they cleaned out the diff and put in new fluid.
Now, this morning, the noises are all gone, but there is a vibration whenever im above 15mph and accelerating lightly. Its not horrible, but defiantly noticeable.
Any thought as to whats going on? Did I kill my diff?
