Should be just the 4 bolt's in the rear of the tran's to the adaptor. And maybe the shift linkage for the t-case. /forums/images/graemlins/grin.gif

they are all 9/16" head bolts between the adapter and tcase.

can you pull the whole engine/tranny/tcase together?

I would just drop the t-case before you do anything. It's just a matter of 6 bolts and it's so light you can just bench press it onto your chest and then set it down. I don't know how old your tranny mount is but if you leave the t-case on the truck with only those 2 bolts holding onto the crossmember you may come out one day and find it on the ground. just my .02 /forums/images/graemlins/dunno.gif

4 bolts between the adapter and the transfer case. One of them is really hard to get to.

You'll want to unhook the shift linkage, the 4wd indicator light, the breather tube, the front driveshaft, and the rear driveshaft.

If you're patient you can lay beside the transfer case on the ground and let it down slowly. With the fluid in it it weighs about 100lbs but you'll get a bath if you don't plug some holes.

When doing tcase and tranny stuff in the vehicle, a good quality ratchet wrench comes in REAL handy.
