88 YJ BA10/5 Removal

Do you boys and girls remove the transfer case when removing/installing the BX10/5 tranny? My manual says to split the two, but I don't know where. The assembly is three pieces with an "adapter" in between the tranny and the transfer case. Do I split it right behind gear shifter or right in front of the transfer case . The center section or "adapter" is about 3 1/2 inches long. Or are you shoving the whole assembly up and in? Gravity helped me get it down, but with it split and help far away, I think I could do the install myself.
Thanks in advance to all!

I did it all together. It helps with a good jack, even if its not a tranny jack, but at least a floor jack with a good size surface, not the little ones with a 3" diameter plate. It will be a lot lighter in two pieces but still not light enough to hold while you toss in bolts. As for an adapter, i only recall taking the nuts off of the studs in the back of the tranny when I changed the transfer case over.

There are (6) 9/16 nuts holding it on to the tailshaft and you'll see the studs that protrude out of the transfer case.

I would split them. It's a whole lot easier to line everything back up with regards to the clutch/pilot bearing without the extra weight dragging you down.

Thanks ffjs87 and IronMaiden!
I think I will split the two because my only help is an "airplane" mechanic and he has to tell me what the hell to do, even though he has never had a Jeep.
I have a 75 year-old neighbor that is capable of lifting the front if necessary, and he always brings beer when he's wonderin' what the hell is goin' on out in the barn.
Here's wishing you a very muddy summer!

We picked up a used atv/motorcycle jack from a pawn shop. It works great for install/removal of transfer cases. It got wheels so it rolls nicely once you've unbolted all the connecting bolts.

I used a floor jack under the tranny to raise it up about 6" then criss crossed 2 ratchet straps under the trans and hooked to the frame rails to kinda make a sling under the trans. Then as I jacked it up I tightened the straps. It kept the trans stable and I kind "swung" it into the clutch. It's getto but it works when you have limited manpower and time....
