OK fellows.... what can I do to just inspect and do some basic maintenance on the transfer cases. How do I make sure they are working ok and how do I change ( or do I need to) the transfer case oil and what do I use. the chiltons only tells you how to rebuild it. I don't wanna do that I just want to look it over and see if there is anything i should be aware of before we try it out. We just bought this thing and were told the 4 WD works fine. How do we check it (other than the obvious "Stick it in 4 WD and try it, dummy" answer.) Anyone ever notice that $ is right above the 4 key so that it's easy to write "$ Wheel Drive"? kinda ironic eh....? must be a premonition.... Red Springs, N.C.
