"planning on atleast 37's not sure yet may go bigger. What years of Fords should I look for to have the axles? What's in the 99-03 f250? I may have a guy I can buy some off."
Definitely have a look at the link that Serious Offroad posted, good info in there.
They started using the the Dana 1 ton axles and Sterling combo in the 70's, and I think its carried through pretty much all the way through. I know my 99 F250 has a Dana 50, but I'm told its nearly as strong as the 60 and not worth trying to upgrade. I also know they used a TTB axle in some of the 1 tons, which isn't the way to go IMHO.
The Ford stuff is by far and away the most commonly found 1 ton axle, so you should be able to find a pretty good deal on it.
37's and the heavy body of a Exploder seem like a good match to 1 ton axles. That is especially true if you might want to go with bigger tires. The Ford is a high pinion version, so it will have better clearance and driveline angles too.
I would try and find a set of OBS F-250/350 axles (pre-98 but still in the 90's), since they have the more common 8x6.5 lug pattern (compared to the stupid 8x170mm that the 99 and up have). Should be common in the yards and being parted out on Craigslist. That would allow you to use takeoff HMMWV wheels and tires, or any number of other 1 ton takeoff wheels from Chevy, Dodge, and the right year Fords.
Chances are, you would be fine with a regear and whatever locker you want to use with 37's. Compare that to really wanting to upgrade axle shafts or at least the ujoints in a Dana 44, and the extra cost of the 60 over the 44 doesn't seem so bad.
