Allison park, 



Thumping noise coming from either the torque tube or trans axel, only when starting in first gear, right after letting the clutch out, while accelerating slightly hard. No thumping under very light start out in first gear. No thumping at any other time, no matter how hard the car is driven thru all gears. The LSD,5 speed trans, and clutch have no issues. I replaced the rear shocks but still hear the thump on take off.
