Its leaking from the front seal it looks like to me you can see where it is wet ariund a bolt and no the thing didnt come with any manuels, any info would help i think it is tranny fluid that goes in it but Iam no sure

Also is it a tie rod or a sway bar that is on the front, it looks like a tie rod but i have heard both, it does connect the two front tires together.

well you can tell whether or not its a tie rod or a sway bar.......a sway bar ties both wheels together to keep the trucks body from rolling in a corner, and a tir rod connects to the steering knuckle on either side so you are able to turn. you should invest in a chiltons or haynes shop manual so you can reference them for help. pop the drain plug off the transfer case and see what fluid runs out then you ll know.

Yeah some kind of reference manuals are definitely in order here.

Chilton's makes the best aftermarket books.
Haynes manuals are okay once you know how to use them.
Most parts stores carry these two types.
Amazon.com has them as well.

Original Shop Manuals are the best but are usually quite expensive.

I think for our trucks Helm only carrys 80 up.  That's why I recommended the other two.  Hope this helps!
