31 Spline Axle questions
What are the odds of me being able to find a 31 spline Lvl II axle anywhere? Where should I look other than a local junkyard? Also, are there any other axles that are stronger that I could bolt into my truck without having to cut any axle shafts or axle tubes? How much would I expect to pay for this? Thanks a ton for your help guys!

There were some '02 31 spline axles floating around on ebay not too long ago, some even w/ the torsen in them. Fair warning though, '02 was the first year of the FX4 (later LII) package. They had some sort of problem w/ the torsens that year. Ford's solution was to pull and replace the entire rear axle on all '02 FX4's equipped w/ the manual trans. My theory is that some dealers/techs nabbed the used axles and were selling them. The torsen could be questionable in said axles. Ford did not replace the axles in the autos.. so they might not be that bad.
If you're going the John Griggs route and replacing the diff anyhow, then it is of no concern. But I like to remind people looking at used 31 spline axles..
Also I believe the Explorer had the 31 spline available as well. Could pull one from an X. Although you would have to rework the perches..

I got one of those axles, complete sans Torsen, for $80 from a Jeeper who had bought it for a project, but then went with an F-150 axle instead.
You can also get Explorer axles, and cut off and reweld the spring perches. Explorers are "spring under" axle, and Rangers are "spring over" axle. Pay attention to pinion angle. An advantage of the Explorer route is that you can get disc brakes on the deal. [Homer Simpson voice] mmmmmmm....disc brakes....
The housing is pretty strong on the 31 spline, with axle tubes as thick as a Ford 9 inch. You can buy aftermarket axles to put in there to make it even stronger.
Frequent the Jeep boards. Mine showed up on the Paragon board and Carl called my attention to it (THANKS CARL!) and I jumped on it.

Ok thanks for the advice guys! I was just doing the "stronger is better" thought process, and I know down the line I'll probably be doing alot harder wheeling than I am now. Prepare for the worst, hope for the best, right? Would the differential from my 8.8" 28 spline work in a 31 spline? My first inclination is to say no, but there's always some hope!
