Junk yard!

 

The AX15 is not difficult to work on.  Having a shop press (or friend with one) is good to have.  Otherwise, some basic tools are all you need: socket sets, snap ring plyers, rubber mallet, feeler gauges...

I visited a couple local junkyards and no luck! I'll keep trying though, thanks!

They're hard to find in some areas.  Don't be afraid to use car-part.com and searchtempest.com to find one nearby.  I had to drive 300 miles to get mine, but got an amazing deal.

I’ve found a couple that are within driving range for me that I’m gonna call about tomorrow! Should I go ahead and get a new transfer case that’s fitted to it or adapt the old one to fit an ax15? Where would I go to get the 23 spline input shaft?

If you were planning on rebuilding your existing transfer case, then go ahead and use the one you have - you can get new input gears for them for cheaper than a new case.  Otherwise grab the one matched to your transmission.

What is the name of the cherokee transfer case that mates to the AX15?

NP231J: NP - New Process; J - Jeep version.

 

Your tcase is an NP231J.  However, it has a 21 spline input shaft.  The AX15 has a 23 spline output shaft.  You either need a tcase that has the 23 spline input or change your existing input shaft.  Rockauto shows 23 spline shafts for $90 to $100.  I bet you could find a tcase for that amount or less.

I was thinking the same thing! Thanks for the info. I may have found a somewhat newly refreshed AX15 for a decent deal. Keep your fingers crossed. Also, does the Peugeot Bell housing mat to the AX15 or do I need to locate a new bell housing?

this is the middle plate.  it's about an inch thick.  the AX-5 and AX-15 do not swap with each other in any way, but do look similar so you'll need to make sure you know what you're buying.  :L:

That looks like an AX15, but it's really hard to tell from just a photo.  Best way to check is put a magnet on the middle plate - AX5 is iron, AX15 is aluminum.

Great. I talked to the guy on the phone and he said it’s completely aluminum!

I’m probably going to go take a look at it tomorrow, but I’ve done my research and he told me the entire thing is aluminum! So I think it’s a sure fire AX15

I'm posting an update about that transmission I posted a picture of. I got it! The story behind it is: the guy I bought it from had a friend who worked for Chrysler that got him a factory rebuilt AX15, and the transmission didn't fit for the jeep he bought it for at the time, so he left it to sit for a couple years (hence the rust on the shaft). The interior of the trans looks brand new from what I can see, it even has the back cover from when it was rebuilt! Since it didn't fit in the jeep he bought it for, he never used it or even put oil in it. It has no miles, and apart from a dirty exterior, is brand new where it counts! I'm making this update post because I have a question. Do different year model AX15's have different sized input/ output shafts? I'm making sure before I order anything just to make sure I'm not having to reorder and return a bunch of things. Thanks again for the info.!

the input shaft diameter is different in early AX-15s and will need a different pilot bearing/bushing than later ones.  outputs are all 23 spline.  :L:  

Would you happen to know what the size differences are? And what year they take places

The early AX15s have a 1/2" tip (89.5 to 93(?)).  The later AX15s have a 3/4" tip (94+).

 

One part to look for is the front bearing cover/retainer plate.  The cover has sleeve the goes over the input shaft.  If the sleeve is short, then it takes an internal slave cylinder.   If the sleeve is long (3") then it takes an external slave cylinder.

 

From the picture, it looks like a short sleeve on the shaft, but I cannot see very well.

For everyone still following this thread, this Comanche is very close to being road-worthy! I’ve got the new input shaft for the transfer case coming in tomorrow. I’ve got the bell housing and trans mount coming in for my AX15 in a couple days along with all new brakes, brake lines, and brake master cylinder. I just ordered a new slave and master clutch cylinder, and a new clutch hydraulic line. Big things are coming up for my Comanche, and I’ll keep you guys updated as I go! Thanks for all the support
