Go buy some bolts the same size as the ones that hold the transfer case and cut the heads off and round the ends really well. Put a couple of these up where the other bolts were and they are a good guide to get that thing out and back up into place. If you get them long enough, it gives you enough space to even get the splines lined up when you are re-installing. It's not a terribly heavy case, but it's awkward. Using those studs to line it up for removal and install makes it a bit easier. They are M10 or M8's, but I can't remember the thread pitch... someone here will know. I don't know if have the tools to do it or not, but the service manual has dimensions for a bracket you can put on a transmission jack. It bolts in place of the bottom cover on the case. That makes the job a snap. If you have the tools you can probably even adapt it to a floor jack, but a tranny jack with head that tips makes it really easy! The right tools make all the difference.
