A torque sensitive vibration is usually coming from the driveline.
Check for loose yokes at the output shaft of the trans, and at the input shafts of both diffs and the output shaft at the rear of the power divider on the front diff. Also check for worn slip joints on each driveshaft, and worn U joints.
I just thought of something else:
Check the harmonic balancer at the front of the crankshaft too, a defective or worn out balancer will cause vibration on a hard pull, and will eventually result in a broken crankshaft if you continue to run it that way.
