    Cant seem to find a thread detailing the procedures for this and the Chilton manual for the truck is too vague (does not differentiate 4X4).

    Can anyone provide what is required to drop the pan, and also what is the best type replacement pan gasket to use?

    All help is appreciated!

    Give me a few mins to find my thread on doing this. It is a pain in the butt and will take alot of time.

    I explain every step it just takes time to read through there's lots of pics to help. It took me a few days, but I also had a rear main leak which made it take longer because I needed to move the tranny. The oil pan only took a day and a half with help. Maybe a whole day only if you read my tips and hardships.

    Wow that's quite a thread............phew! Lots of twists and turns..............
    and I still can't see what it would take to drop the oil pan.

    Still looking for some help on this guys.

    Ill sum up. First you drain oil and remove the oil filter and filter adapter. Next you will remove the front drive shaft. Once that is out of the way you need to unbolt the y pipe from the headers(yes you need to do this). Now you will remove the tranny supports which are the two rods coming from the engine. Now you can take off the torque converter inspection plate and remove the starter.

    Now for the pan removal: Support the front axle and unfasten the axle mounting bolts. Now you can unbolt the oil pan and let it drop.

    I can not stress it enough you need to get the exhaust pipe loose and if possible remove the entire y pipe. I was luck me and my friend were able to flex it out of the way enough to remove the torque converter cover. If your alone that's not gonna work.

    I'll start soaking everything in PB Blaster days before - that always works.

    I'm not sure exactly what bolts u are referencing for the axle mounting. I'll have to look under there or in my manual.

    I appreciate the quick break down - thanks!

    Darn the one thing I dont have a pic of..... They are the bolts that hold the front diff to the frame.

    Use as much penetrating oil as possible. Buy tons of it and get WD-40 to clean to bolts and parts you remove(it works well)
