I have a '93 fox and recently it started having this issue.
When I hit around 60-70 mph and let off the throttle it vibrates terribly. Soon as I touch the gas again it almost goes away completely. So I know it isn't a wheel balance issue. I had them checked to be sure. I have a FRPP aluminum driveshaft. I have a FRPP super duty T-5 (rebuilt around 3,000 miles ago). New differential carrier, new axles, bearings and seals. I haven't changed gear ratios. I am currently at 3.55.
I am wondering if anyone else had this same issue and what they did about it. I'm thinking it is a worn part somewhere because it started well after rear end was done.
