XJ D44 vs. MJ D44 rear axles

[1990 Pioneer 4x4]

Are they the exact same (length…) except for the missing perch mounths? I suspect it would be easier to find one for a XJ and add mounts.

Identical except for perch location and MJ ones do not have the shock mounts.

 

It may be easier.. it may not. I've never seen numbers, but I suspect that MJs actually got more 44s than the XJ.

not to :hijack: i have an xj d44 and would like to know where the spring perch goes so that i could have them replace i intend to go with a SUA vice SOA so if any one would have the spec's it would be greatly appreciated

In SoCal we have found may more XJ 44s than MJ 44 in the yards.

Somebody could give you the center-to-center spacing (I think Pete M has posted a photo with that information), but you also have to match the location on the circumference of the axle tube to get the same pinion angle relative to the spring perch. I've never seen anyone post that data. Most people pull the original axle, set it up next to the XJ D44, and just make everything the same.

some day I really should add in that info. :( I believe it's 42" center to center for an MJ.
