Well, I had a very productive weekend. Finished a lot of small stuff in order to get ready for the upcoming state inspection and upon a very short test drive, things went real wrong. As I was pulling out of the driveway and accelerating lightly, the car lost power, the engine continued to run well, no bad noises. At first I thought it was the clutch letting go and slipping. (The setup is 390FE, tremek tko, hays pressure plate and clutch, ford 9inch with posi and 3.70 gears). I pushed the car back in the garage, jacked it up and was ready to remove the tranny to get to the clutch when it struck me to check the rear end. I spun the wheels by hand and watched the driveshaft, the driveshaft spun when the tranny was in neutral, so i put it into gear and thats when it happened, the wheels spin, but the drivesaft does not. No terrible noises are heard and it feels smooth. It feels almost like the the gears are not messing.

Conclusion: clutch and tranny are fine, rear end is slipping.

The rear end came rebuilt and together with the axles and completely assembled so I never had it apart. What should I look for. Any and all suggestions are appreciated
