JK and WJ Axle Geometry

[Root Moose]

Does anyone know off hand if the JK and WJ axles share the same control arm mounting brackets on the axles?

Wondering if JK axles are an "easy" swap onto a WJ...

TIA

I don't believe they do. I have a friend who is swapping in jk 44's into his wj i will check with him and let you know.

I thought I read of a guy on colorado4x4.org who swapped JK axles directly into his XJ. Not sure if that's any indication, but I thought WJ & XJ axles were swappable (with the exception of bolt patterns of course)

Is the JK axle not significantly wider than the WJ?

or is that the point?

Spendy conversion...but axles are never cheap. On the plus side, you've getting a trussed JK 44. Throw in a set of sleeves in the front, gusset the C's, and some chromo shafts and you'll be ready to run 37's...or keep it at 35's and your axles will last a long time, even under abusive conditions.

I spoke with my friend tonight and they do not.

i believe tj, zj, and xj axles swappable. Not sure about xj and jk axles being swappable i don't think so(at least not easily).

XJ's have rear leaf springs. JK's have rear coil springs.

Even if track width was the same (JK's are wider), the difference in springs would mean that it couldn't be a straight swap. It may be a relatively "easy" swap, but you're still going to be making some substantial changes to either the JK axle or your XJ.

lol i forgot xj's had leafs in the rear

Well, the rear upper of a WJ is a "3 link" type set up and the JK is a 5 link.

Here is a picture of the WJ rear suspension. (Stock)
