I plan to..Once my garage/shop is done I'm going to officially start ordering parts (3 weeks from now roughly) find an axle and start this thing. I think if I can successfully re-gear, lock (or lsd) and reinforce both axles for $2500.00 or less it ought to generate some interest, though I'm sure its been done before.

Hows about a Ford 8.8 out of a ranger or exploder? In stock trim they are wayyyyyyyy stronger than a D44 and cheaper to build. TJ guys have done this. Stock TJ wheels fit it since it is a 5 on 4.5 bolt pattern. I plan on doing a build myself since a pro rock is out of the question for now and people think a D44 out of a Rubicon is worth gold and housing wise it is no stronger than a D30.
As an added plus, there seems to be a lot of them floating around.
Cost $200 used at bone yard or Craigslist.
Its just the right width.
$200 for JK bracket kit.
$299 for a cheap locker
$100 for steel to weld a cheap truss to it.
Edit, NM you are doing a front axle. In that case there are plenty of D44s out of them for $200.

In the future, mabe another axle swap wil be in the plans. But for now, I'm keeping it cheap, simple, and something other people can do.

For anyone interested in doing this, I found some good, unbiased info in an article by 4wheeler magazine. The below is copy and pasted from that article.
"But did you know that you can improve the strength of a ring and pinion gearset by simply having it cryogenically treated? Cryogenics bathes the metal in liquid nitrogen at minus-301 degrees Fahrenheit. The process changes the state of the metal, making it much less likely to develop fractures or cracks. The results are, in the simplest of terms, stronger, more durable metal with a much higher yield strength. We sent our Dana 30 gears out to Cryo Science of Oceanside, California, to have this treatment applied. When the Dana 30 gearset was returned to us, the strength was nearly the same as that of the Dana 44 unit in the picture"

Wow. I bought my gears already cryo treated from a forum member who never installed them. 'Til now I was dubious about the benefit in this application, but now I think it might be a nice bonus.

Yeah x3. Got my attention to say the least. I'm gonna try to find the whole article again, VERY good stuff. For the pricepoint you can't beat it, even if its not quite as strong as they say.

Cryo treatment makes the gears less likely to propagate micro cracks from machining the teeth as you have tightened the "grains", therefore protecting it from failure, but I would feel this process makes them more brittle, less ductile, so sudden harsh violent loadings could cause more catastrophic failures compared to standard gears.
I'm not denying they're stronger by any means, just stating failure events might be much more violent and damage causing to surrounding areas.
Definitely cool info tho

"Tougher" is the term I've heard used to describe cryo'd parts. Anyway:
