Axles for a quadratrac?

1st off, this is a great forum with a lot of good, quick answers to hard to find questions...

2nd, what are some good strong axles that would handle 4.88 gearing, ARB locker, Disc Brakes in the rear for a quadratrac offset, and perhaps a bit wider than the narrow trac axle?

The obvious and easy answer is the axles from a full-size Cherokee or Waggoneer - A Dana 44 front and either a 44 or a heavy duty AMC 20 in the rear. On a CJ those are good for some very hard wheeling, especially if you have an automatic transmission.

Oregon, huh? I have a Wagoneer with an offset HD 20/ Quadratrack that I'm going to be parting out this spring. I'm probably keeping the front, but not the rear...interested?

You should be able to find an offset rear from a waggy pretty cheap as no one uses them. I didn't know they made offset amc 20's, I thought they only used the dana 44. They will handle 4.88's fine. I'm in the middle of swapping down to 5.38's.

Yep. I found three or four of them in junkyards while looking for a front 44, and didn't see a single rear 44.

randyzzz? is what you have a dana 44? I may be interested in that, but if folks say the amc 20 is good to go, I'll leave it. it does have 1 piece axles in it, 4.88 gearing, and an arb... I would hate to have to start over again on that. I'm tempted to just put a disc brake conversion on it and go till I break it, if I break it?

With the locker and 1-piece shafts your '20 should be good for about anything you'll throw at it. Personally I don't think rear disks are worth the effort and wouldn't mess with them, but a lot of guys here disagree, so . . .

The rear I have is an offset HD 20 out of a 77 Waggy with Qtrack. 3.07 open. I have a centered 44 rear housing out of a 90 Waggy, and a centered HD 20 also (actually I have a pile of waggy axles).

IMHO, if you find an axle to your liking, offset or not, run it... Despite folks thinking the DS can only be angled downward from TC to pinion, it'll also run sideways at the same time. While many call it a "compound or multiple angle", WBCarver set us all straight years ago that it is in fact a single angle. As long as the joints at either do NOT bind or DS contacting a fuel tank/etc., it ain't gonna hurt a thing!

Case in point, my D44 rear and the TH400/D20 do NOT line up perfectly... 3"-4" difference (BTW, this is from the factory)... outside of trashing a couple joints (which I've attributed to normal due to abuse), it's given me ZERO problems in 5 years...
