Re: Jeepn,D30 question
So basically you're only using the YJ centersection right? You can also use D44 shafts in the D30, or at least the D44 joints, the 1995 YJ's and the current TJ's use the larger 297X joints instead of the 260X joints in the D30 you have. Retubing the axle is a good idea, most people don't want to put forth the effort to make a good axle. You do realize 4.56's are the lowest gearing available for the reverse cut D30 don't you? You can swap the sides and use stock shafts, the long shaft from an XJ (Cherokee) will fit in place of the vacuum disconnect side of the YJ D30.
Unfortunately the YJ D30 isn't the same as the TJ or CJ D30's. I don't know anyone that has done it, but you may, and I emphasize the word may, be able to put the CJ tubes on the YJ pumpkin, in the reverse order of the YJ setup. IF this can be done, you can convert it yourself to a high steer setup using J-truck or Chevy parts, all of which are mix-and-match and over-the-counter. You can also get the internally splined hubs, which are much stronger, and the 5x5.5" bolt pattern instead of the 5x4.5" of the YJ. This will take some work, but it's been done by a few people I know, and it's a worthwhile swap. I think I may convert the D30 I'm swapping into the Zuk to a high steer setup, but I'll see if the need is there first.
You could also build a D30/D44 Hybrid, the Scout II front D44 axle had some outer parts compatabile with the CJ D30, so maybe the tubes could be grafted together for an easier swap. So many possibilities, so little time!
