Dana 60 From J10 For Mj?

[Scottracer]

Hello,

I was wondering if a Dana 60 Rear from a J10 pickup will work in a MJ?  I am thinking there would need to be some level of modifications but just not sure how much.  Are they all pretty much universal?  Length depending I guess which can be fixed but I would consider that more of a major modification. 

Thanks for your help.

Anything can be made to fit if you really want it to but I am not sure the width of it but I think it will be really Wide compared to your front axle...

 

There are easier swaps to do that have easier solutions for the front axle...

 

 

Is this for a DD or weekend warrior?

J10s have Model 20 or Dana 44 rear. Not Dana 60. J20 has full float 8 lug D60 and 71-73 J4000 came with single bearing D60s with 5 on 5.5" pattern (like CJ)

The width of the J10/J120/Wide-track Cherokee axles was about 5" +/- wider than an MJ. The narrow-track Cherokee and Wagoneer are closer to a match in width at about 60" +/-. The rear swap is as easy as cutting off the perches and welding new ones in the correct place and adding shock mounts where needed but that would leave you with either a 6x5.5 lug pattern on a D44 or M23 or 8x6.5 pattern on the D60 (ignoring the early D60's and D44's as they are significantly weaker than the later versions. ) As the MJ has a 5x4.5 lug pattern and I know of no adapter to make them match nor an easily/cheaply adapted 6x5.5 or 8x6.5 matching front axle that would be a deal breaker for me. 

 

The FSJ corporate axle was actually the Model 23 to differentiate it from the trouble-plagued model 20. I have not been able to get anyone to confirm if the MJ had the 2-piece axle shaft M20 like the CJ or the stronger 1-piece axle shafted M23. It is easy to tell the difference by the flat hub center on the one-piece M23 and the spindle protruding on an unconverted M20.

The Model 20 found in select 86 MJ "Metric Ton" rigs has one piece axles and heavier duty housing like the FSJ variant, not the weaker CJ 2-piece style with the weker axle tubes.

Yup. The MJ Model 20 tubes are thicker steel.

Cool. Internally those were known as the Model 23 and they are a dandy axle. They fix all that is wrong with the Model 20 and the center section is a stout one inside and out. They used those diffs in Humvees and H1's but adapted them to IRS/IFS.

They gained clearance with the hub reduction drives.
