Make sure that you have an oil pan nearby. When you take front drive shaft off, the transfer case empties. No joke. I just did it and had to call a friend to get him to bring me some Gear Box oil ASAP so I can get the van out of there.
don't pull out the yoke and this is not for racing down the road at speed. It's a test to move forward/backward to see if the transfercase is engaging or not. If you pull out the yoke from the transfer case output cone, it will leak.
