i dont have any step by steps available to send out on the comp.
umm, you gotta take out the entire front suspension. front diff. and all. there are write-ups for just about all of that stuff I believe. Once its all out, there you will see all the bolts you need to pull. there are 2 black 'plugs' on the back side of the pan that you will need to pull out. I used a pair of vice grips, grabbed on and gave them a spin and a tug. there is one nut on each side up there a ways, you will need atleast a 12" extension. I believe all of the nuts and bolts to get that pan off are 13mm. there are also two, umm, maybe 3 bolts from the tranny forward to the pan. those may be 15mm though. you will need to remove the oil filter relocator from the back d. side of the pan. Once all that is out, it should pretty much come on down. I had to do some twistin n/ turnin to get it down. it was gettin cought up on the pick up screen.
uhh, thats all i can think of. your other option is to pull the motor. and do it that way.

feel free to ask anything else.

CompoZr2, you should really make that a sticky because what I just read seem very help for people who are in need of taking out of an oil pan. Too bad you didn't have picture when you were doing yours.

BTW, how that valcover gasket doing? Still leaking?

ya know im not really sure!
i'm got a hunch its the oil pan gasket but i also think there may be a hair line crack near the top so i ordered a new pan and gasket up and gonna put em on anyways to cover my bases. also gonna replace the front timing cover while i'm at it
someone before me had it off and the idiot first of all reused the thing and used household caulking to try to seal it up!

I hate buying a truck from somebody and fixing their mistakes. For example on my part. I brought the truck and he screw up the front end (badly out of line) and screw up some of the 4x4 hosing.

Yes, that is a very good idea to do things on the motor since you have it out.

Might want to consider doing the intake manifold gasket as well?

Good luck and keep us posted! thumup.gif

Front diff ass. means everything. The assy is considered the pig itself, but everything else has to come out for the pig to come out. You can pull the motor if you'd like. but you cant raise it up enough to clear the pan from the front diff. Therefore you have to detatch from the tranny. if your goin that far, just pull the motor and do an overhual as you stated. Be sure to get some RTV for the corners of the gaskets! I had some pics, just not any that are gonna help with a how-to process. here is my post

I have the exact version of directions abright has. just in paper form so that does you no good. glad someone had access to them. follow those step by step and you'll do just fine. ask if you have any questions.

when you raise the engine can you unbolt the front diff and move it out of the way enough without having to "remove anything" ?
