Any writes up on how to do this? This will be my first attempt at this procedure... any input is appreciated.

I am swaping out

- man tranny
- T-case
- and both diffs (that is correct isn't it, I know you are suposed to do the rear but I am not sure about the front)

Any idea how much gear oil I will need? I figure I will be safe if I buy 12 quarts.

For the Man. Tranny there will be a drain plug on the bottom of it, pretty decent sized bolt, dont take it out yet, first take the top one out, it should be on the drivers side of the tranny. Unscrewing it first ensures a smooth flow while draining. Now pull the bottom one out and be ready to catch the fluid in a container. Put a new crush washer on the drain plug and re thread it in. Now fill it in the fill hole until it starts to seep out, then it is full and screw the fill plug in.
Repeat the same for the x-case, it's obvious which ones to pull, they are the big ass 6 points.
The rear diff is basically the same as well but on the front, remove the skid plates then you have access to the front diff. P.S. Get a cheap pump and hose and it makes this a whole lot easier for all of these fill jobs.
It's pretty self explanatory, if you can put gas in a car you can change your fluids.

A pump makes the diffs easier or everything easier?

I didn't jack the truck up or drop the spare, I just slid underneath. I used a half-inch drive socket set and a hammer to loosen all the plugs, the front diff was unbeleivably tight. Just make sure you have a good pump,with it it will only take you an hour or so, otherwise you will be there all day.

You'll need a 24 mm socket, preferably a 6 point, and a breaker bar is nice too but do NOT re-tighten the plugs with the bar, use a torque wrench. I can't remember what size the socket head plugs are on the front diff but like someone said, they are in there very tight. Take the fill plug out first to see if it will even come out, so you don't drain all your fluid and end up not being able to put it back in, which would suck. The differential drain plugs have magnets, clean 'em off. Don't get the gear oil on you or you will stink something fierce.

Listen CAREFULLY to the above! The transmission and trans case are aluminum housings and can be stripped VERY easily. Use a torque wrench and be careful!

Trans drain plugs 27 ft/lbs

Transfer case drain plugs 27 ft/lbs

Front axle drain/fill plugs 29 ft/lbs, plugs are 10mm in size.

Real axle drain/fill plugs 29 ft/lbs

Try to do this job on a warm day. This stuff gets thick as syrup when it is cold.
