been there done that
Changed the clutch on a NV5600 and left the transfer case attached. Even with a good-sized transmission jack under the 6-speed, and a floor jack under the transfer case to help balance and stabilize the load, it was still a BIG handful for THREE of us to wrestle in. At over 400 lbs, its more than 2X the size of the 5sp. Great comparison photo in the latest TDR. Pulling the 5SP should be a walk in the park. And yes, the nose of the engine wants to droop with the transmission off, so your support for the engine needs to be up front... won't take much as engine almost balances on its mounts. Good luck and have fun!
