I just did my 2000, dunno if its the same but I just kept trying till I got it. It's at a weird angle and I had to do it blindly by touch, but 4wd works now.
I have small hands though.

I use a swivel head ratchet with a deep socket and go over the transfer case from the back side. More than enough room even for my big hands & the forearms.

Transfer case control motor. It may very well have stripped gears. On BF homepage in the google bar you can read more then you ever care to learn. Just so you know it's not horrible.
