need some help
i have a 81 wagoneer with rebuild amc 360/4 speed dana44 up front and amc20 in rear.
may have a line on some newer ford(superduty) 1ton axles.. dana50 front and dana 60 rear with disc's.. just wondering if this option will work or if i should go another way(dodge ect..) to make things easer..
any help please
oh also if i do this i will have both 1/2 tone axles for sale..locked front and rear 4:10's..

stay away from the d50
unless i am mistaken it was only a limited use in the f250
parts could be hard to find
i could be wrong though
i believe the outers and stub shafts are different..
typically 8bolt x6.5 centres

The ford diffs will be the correct side frt diff for your wag, but I haven't heard to much good about the Dana 50s either the other problem you will have is the wags even though are considered a full size the diffs are a fair bit narrower than ford stuff you are lookin at so you will end up with the tires sticking out a ways from the body.
i think the easiest way to go would be a d44 and a d60 out of a j20 but im sure someone else will have a different opion.............i have a j20 with this set up in it if you want to look at it pm me im in nvan also..............i think we have waved at each other in passing before [cheers]

For his wag he would need to stay with 1980 and newer J truck diffs for the frt axle, 79 and prior are the wrong side drive and the J truck and 2 door Cherokee diffs are wider again than the Wagoneer diffs.

yah j20 diff about 5" wider, over all, then what i got..but thats fine with me. i wantted wider diffs as i have flares, and also my diffs are to close to the inner fenders for my liking now.. but finding a j20 with a 60 will be hard...
that why i was wondering about the ford...plus i know the dana50 is high pinion witch may help.. thanks sofar.. im still trying to deside..

just put a 3/4 ton GMC axle in place of an AMC20 on my '80 Cherokee. I was surprised at such a weak rear end on a Jeep ! Little modification to make it work but I'm locking 'er up at the same time.You've definately got options

so ScaryCanary what are you going to do up front??

if they are newer ford it wouldnt be a dana 60 would it? wouldnt it be a 70 or a 10.25?

opps my mistake.. yes your right the rear is the 10.25.....

with a dana44 up front, I decided to go posi on the front instead of locking but the gearing is up to 4.88:1 now. Went with a 4:1 low in the transfer case as well. My new torque converter should hold up much better than the stock one I replaced.
