#jeeproblems just once i'd like a prob thats easy not like this trans

the jeep gameshow. behind each door is a stack of bills:

door #1) i can pick up an ax15 for 300. (and spend a stack on conversion)
door #2) i can swap the ax5 thats currently on the work bench for 400.
door #3) i can rebuild 5th gear sleeve and all his little broken relatives for like a billion (but i gotta find a press to get the sleeve apart.

im open for any and all suggestions, including a bullet to my head.

A bearing just went in my ax5.. funny I see this because I'm in the exact same predicament.

personally, I think I'm going to go the door 2 route as I can get a used ax5 for about 175

I looked into rebuild kits and they're about 170 by themselves, then factoring in any replacement parts I may need seems to be a bit much

thanks...i wish i could find an ax5 that cheap. heres my math:

installing used ax15
$ 300 trans
$ 150 conversion kit
buying used ax5
$ 400
rebuilding current ax5
$ 200 and higher for kit
$ 50 5th gear
$ 100 5th gear main shaft
$ 100 needle bearings
? 50 for use of a press
the one bullet to the head solution
$ 29 for one box of 38 cals
$ -0-.357 magnum that the cheaper .38's will fit into

i wish this was just about the math.....pulling the trig would pull me out of the jeep hellhole ive fallen into.....haha

Me, I would go the AX15 route with everything you would need to bolt it up INCLUDING the external slave, but that's just me.

Go with the AX-15 and the 8.8 rear. Big time. Just check em over carefully before handing over $$$. You should be able to find an AX-15 real cheap in an XJ Cherokee in almost *any* junkyard... you'll be without the jeep for quite a while, but I do believe it'll be worth it. Just to make that thing bulletproof. Hopin you can get it all in before the holidays (snow is a 4-letter word in my book... lake-effect.)

It is a better and stronger tranny than the AX5, I have read here that you can use it with a small block motor, can't do that with the AX5. That and if you get the external slave you just crawl under the jeep to replace it, you no longer have to pull the tranny and transfer case.

Well worth it in my book.

The XJ AX15 is clocked at 23 degrees for the transfer case. The YJ is 18.

I could be wrong though.

the splines on the output shaft of the AX15 and AX5 are different, your NP231 probably won't mate up with it. I had that problem (well I had both transfer cases so it wasn't really a problem).

Grab an 8.8 and an AX-15 from a junkyard in one trip. you'll need a spicer adapter to connect the shafts with a u-joint as the pinion on the 8.8 has a flanged end. Also, they sell spline adaption kits to convert from 21 to 23 splines (not cheap tho). It might be more economical to find an NP321 already attached to an AX-15

buy the NP231 that is attached to the AX15 you buy.

You are correct but that can be fixed with a 3/8 drill bit.

The AX-5 and the AX-15 have different input shafts and output splines so it maybe easier and cheaper to just grab the whole trans and t-case both together as an assembly out of an XJ Cherokee, and then re-clock the t-case to fit.
Grab the clutch too.
