4/4's don't have an LSD as standard, unless the Sport spec was different ?
Sounds like the drivetrain rubbing on something, check for play in the UJ's, is the handbrake outer catching on a propshaft flange, also look at the engine mounts if the rubbers gone off in one side it will shift as described with power on / off
