Write up for gear oil swap?

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.
