I haven't detailed a filter change on my instructions as it's just a fluid change, but hope to do a filter tutorial soon. If you look in my gallery there should be pics of the TOD/transfer case along with the diffs indicating drain and fill points. All three are pretty simple though, simply drain from the bottom and then fill to the fill opening. I've used Mobil-1 gear lube with excellent results, but you still need LSD additive for the rear. ATF goes in the TOD/transfer case.

Remember to disconnect your negative battery cable before you get started! Ya don't wanna get squished.

EDIT: Here's the gallery album with the drain and fill pics - http://www.vehicross.info/gallery/sh...y.php?cat=3058
