I just got my hands on a '76 Jeep J-20 front axle and it looks to be a great candidate for going under my toy. The short side axle is ~16.75" and the long side ~35.25" and it has flat top knuckles. This is great for toyotas because I can cut a few inches off the long side run a wagoneer shaft and have a 62" wide front end once I get the chevy stuff for 6 lug. Also sense it is spring under I can esily weld the perches on top to give me whatever pinion angle I want, much simpler then a chevy axle. Basicly if you want a 44 front look for a J-20, or a J-10 may even be the same but will even have the 6-lug stuff!

Good info, but arent those kinda rare? Might be why you dont see more swaps with them.

Good find! I personally don't like to add spring pads though because the passenger side one is cast into the diff along with the guide for the u-bolt and it is hard to get the pinion inline with the transfer case when you start with the spring under housing.

You can't put the pinion wherever you want it without turning the knuckles. Also 4 door wagoneers are around 61" wide wms to wms, and are sprung over too. Having done both chevy and jeep D44's, the chevy was easier. Both required outboarding the frame, but I didn't have to spring it over and mess with the cast housing, or 1/2" shim to level it out. Also I "milled" my chevy pad with a 4.5" grinder after I truned my knuckles. It took about 20 min and I also reworked the ubolt guides to accept the new angle.

They are kinda rare but if anyone has a jeep junky freind shouldnt be tough to find, and like I said I *think* J-10 front axles have the same shafts.

Dirty harry: as far as spring pads I like adding my own because I can set the pinion angle a little nicer then a chevy where the perch is cast in. Yes one U-bolt is going to require some grinding on the housing but the other will be fine.

I'm still not sure if I'm going to cut of both knuckle "C's" and reset pinion angle. I will probably just tack the one side in place and bolt it under the truck and get weight on it and see how things work out, hopefully I can get away without turning the knuckles.
