Has anyone got any details on how to do this without removing the transmission? Any specialty tools needed? Even just where to start from would be a big help, I can find it in a parts diagram but that doesn't really show where it lives in the grand scheme of things.

You'll have to remove the transfer case, that's where the VC is.
You might be able to remove just 2/3 of the transfer case, leaving the bell shaped piece that attaches directly to the transmission.
Or you might have to remove the whole transfer case. It's been so long since I've tore one apart I can't remember specifics.

I'm assuming the long shaft he referenced is the one that usually stays with the transmission when you separate the transfer case and transmission.

Looking at the shop manual it should be able to come out with just the right side axle and right cover of the transfer case assembly taken off but I can't be sure because the manual seems to skip some steps.

What CST rating fluid are you using?
