I took the Mustang out on a hundred mile trip, broke down and had to be towed 100 miles home. While I was on the interstate, I heard a loud clunk clunk clunk noise and smelled burning rubber. It proceeded to turn into a deathly wine when I tried to accelerate. I got of the interstate, and the car continued to clunk even at a snails pace crawl. I though that I might have a sticking caliper, so I removed both of em. Found out that the noise was present when the brakes were removed (vehicle on jackstands). Also, when I had it up on the stands (rear wheels suspended from the ground), I noticed that the right rear wheel (traction wheel) was not spinning whereas the left rear wheel (driver's side) was - with the car being in drive. I'm thinking that I need a new rear end, but I'm not certain. Anyone else have this happen? First time I've ever ran into drive line issues. 1995 Mustang V6 3.8 with new headgaskets at 195k.
