Thanks man. I paid $200 a piece for the axles. I had to drive 2 hours to a junkyard for the front axle because it was the only high pinion Dana 30 with 4.10 gears around. Worth it in my opinion tho.
Unfortunately it wasn't as simple as just putting these right under the jeep and going. The 8.8 had no brake hardware whatsoever and the front. Dana 30 was rough. I have an additional couple hundred dollars a piece wrapped up between the two. (ball joints, wheel bearings, diff covers, conversion kit, brakes etc)
Fwiw, in my opinion, if you aren't going very big on tires, say you stay 35" and under you would be better off running your Dana 44 rear and trussing your Dana 30 up front. It will make it fairly strong compared to a Dana 44 front end and be much easier on your wallet as well. Just from what I know I paid to get these done, I can only imagine what Dana 44's would cost to build up. But like I said, that's just my opinion.
