Sorry for the hijack, but I would like to clarify. There are a few posts saying the transfer case is not rotating when the truck is stopped. I know the OP didn't say he put the transfer case in neutral or anything, but won't the PTO drive gear at least work (rotate) with the truck in a drive gear but the transfer case in Neutral? I guess technically these are connected to the transmission output shaft, but the gears are inside the transfer case.
