Well the rear diff is pretty self explanatory, but how in the world do you change the front differential since it like, bolts onto the frame or whatever's going on there? Also, there's orange...like silicon? I guess around a few of the bolts on the differential and around the entire edge of it. Is this factory or is it safe to assume someone changed the fluid already? Because if someone has before, I'm not going to attempt it.

idk on older trucks but the new ones they pump the old fluid out and put new back in throught the fill plug.

[Redneckstone]

you should have a cover on the I-beam for the diff

[zabeard]

if that is true it is prolly as easy as the rear? no?

Yes, for the new SLA 4x4's it is a biatch. The fill plug is right above the frame rail and right below the body. You have to use a fluid evacuator to get the fluid out, but it has to be a tiny *** hose since it has to bend really sharp to get down to the fluid. Unless of course you drop the whole diff and pull the cover. To fill it back up with it in the truck it's easiest to use a fluid evacuator that is also a pump. Because there is no way to hold the bottle remotely close enough to fill directly from it.
