Guys, Have had violent axle tramp on hard take offs, to the point where I'm too scared to hammer it off the line, as the whole rear end just bangs violently. (usually the left rear end) Took the car into Ford and they changed all diff bushes and also changed the tailshaft, but it hasn't solved the problem. I'm sure I'm not the only one with an FG XR6T that has this problem...(well I hope I'm not)...has anyone been able to solve this great mystery of the universe? I would have thought Ford would have been all over this issue by now...
