Thanks for the reply, it pried off as you said. Wow, you weren't kidding about those bolts on the driver's side being a pain, but as you mentioned, flex head ratcheting wrenches did the job (albeit with a lot of grunting and groaning).
When I went to put the new one in, I noticed I was going to have a hell of a time! There are no studs sticking out of the front of mine to pass through the transmission, but the holes where the studs should be! Looking at the old transfer case now removed, the studs are threaded on both ends as expected. There's no where to grip them or get a wrench on the old ones, and channel locks mar them up without turning them.
I'm thinking Motech removed them so that they wouldn't get damaged in shipping? Going to have to call the dealer tomorrow and try and find out if they are even available locally. How do those get torqued in? There's no where to grip them.
Did everyone's transfer case come with the studs already in it to mount it to the transmission?
