Car shakes when moving from a stop
Issue: When I start moving from a complete stop, there is a shaking coming from the rear of the car. It feels like it starts at the rear diff and goes all the way through the clutch (I feel it in the shifter as well). The shake goes away as soon as I let the clutch out completely. Basically it happens as I am slowly releasing the clutch to roll out of the stop and it starts to engage and then stops once I start moving.
Setup: toploader 4 speed, centerforce clutch, hurst shifter, stock driveshaft, rebuilt ford 9" rear end with 3.50 gears and trutrac, rear sway bar, 4.5 mid-eye grab a trak springs, delalum bushings, classic red koni shocks (one half turn from soft), traction masters traction bars, 245/60R15 tires.
This is something that started once I put on the new rear suspension and trutrac. I thought I was getting wheel hop with the new leafs and bigger tires so I installed Traction Masters (which look awesome), but it is still happening. The only other thing I can think of is that the lowering of the car messed with the driveshaft angle, but is there something else I might be missing?
