Check the clearance between the driveshaft and exhaust pipe. If you removed your front track bar, could be that when you accelerate, the engine mount flex combined with driveline torque bring the shaft and down-pipe together, causing a rattle. Could be less noise or more noise when in 4WD. That's been my experience anyway.

Have you greased your front ds? That makes my sound disappear.
