Sorry dave, I missed that you were in the UK! I usually try to notice those things. Not that I have any new pressing info now, but at least I know it is probably not your exhaust
Since you have QD diffs it will be harder to turn when on a lift compared to an open differential. Even with your Tcase in neutral it, spinning one rear tire will spin the drive shaft and the internals of the Tcase. Yes, disconnecting the rear drive shaft will allow you to spin the tires more easily and listen for anything dragging (the opposite side tire should still spin).
If it is not pad/shoe contact creating the extra heat, and all those parts are working properly, the next suggestion would be the wheel bearing, or do not let the little extra heat worry you.
