The flex bags made the process simple and less messy. Yes, the manual says 75W85 but 75W90 is fine. I use 75W85 Redline, but that does add to the cost.
Transfer Case:
Buy 1 (though you may need 1 more to get exactly 1 quart in there, unfortunately I haven't seen these in a flex bag, you'll need a pump):

Robot or human?

Not sure why it's saying Robot or Human ... Okay to click on it as it goes to Walmart.com

As always, ensure you can open the fill plug first prior to opening the drain plug. On your ELSD rear diff make sure you don't open the wrong "fill" plug.
I've got 133.5K on mine and am just now debating whether or not to change the fluid on the transmission. My local MOPAR tech, that does weekend jobs, told me not to change it, though, I'm still thinking about it. If you have the MaxCare Lifetime then I wouldn't consider changing the transmission fluid.
