the clutch dics in the transfer clutch are shot. they do not have enough grip to drive the rear wheels under load.
try this, unplug the TCU under the dash. this will put the car in ''limp'' mode and you will have only 3rd gear plus reverse. it should also cause binding in slow tight turns. the front and rear wheels will be ''locked'' and will have to turn at the EXACT same speed.
no binding means no grip in the clutch discs.
