On my 2003 Buick Rendezvous AWD at 60,000 miles, I have a whomping noise in the differential. I changed fluid and that corrected the problem. At 71,000 miles, rear end is so loud you can hardly ride it, noise starts at about 15 mph, and gets louder with speed. Could this be the differential going out? And if so what are the procedure in changing out the differential? Thanks for your answer.
