The drain plug and fill plug will be the same for those transfer cases.

The Plug, closes to the "ground", is the Drain Plug.

The plug, furthest away from the "ground", is the fill plug.

we got the selec trac one, its awesome, since my wife drives the liberty it is important for me to know she is safe n sound and can drive in 4x4 mode without messing up the tcase
im prolly gonna do the tcase next weekend along with the brakes, the squealer is almost touching the rotor in the back already.

Ok, so far I have changed the rear diff on my '11 Libby by pulling the rubber plug and suctioning the old stuff out. Both my suction pump and my quart bottle refill pump are still working great at 15yrs old. I did my homework on gear lubes by downloading a white paper pdf from goodsenseoil.com. You will know just what a gear oil goes through as far as testing- much more extensive than I ever thought. They tested a dozen or so brands of gear lube and I was surprised that Royal Purple made a rather poor showing up against the completion. Amsoil edged out on top, but I went with Valvoline syn power as it passed all the tests and was one that was military grade rated and placed in the middle of the bunch and since it was so much cheaper to buy than many other synthetics and on sale to boot at 6.99 a quart, it won me over hands down. As far as I know I pulled out the factory stuff at 54,000 miles, as I bought this jeep used. I used 75-140 in the rear and I bought 75-90 for the front, as well as Valvoline full synthetic trans. case fluid that is rated for atf +4 . I took a quick look under the front and as near as I can tell there are both drain and fill plugs for both the front diff and the trans case. I plan on doing this maintenance more often than the last owner. It is fairly easy, and I can use a tested full synthetic for a price that suits my budget. Now if only my oil filter was as easy as these other things.

I did all those things a few months ago. Well worth the savings by doing it yourself.

I would never suck the oil out, better to remove the cover on the rear, clean it out good and then you know there are no major issues.
As far as what to use, dino works better at clinging to the gears than any synthetic does
