93 ZJ 249 to 231 T-Case swap

93 ZJ, 4.0, auto, NV249

OK...so apparently the VC in my NV249 is taking a dump. After driving to/from work, when it's warmed up, the front end is skipping and binding. I'm told thats classic VC on it's way out.
Yanked the front drive shaft today to avoid damaging anything.

I've been told it's a direct swap to go to a 231.
I found a used 23 spline 231j from an XJ on EBay for $200, and it's on the way...should be here in a few days.

Can anyone confirm this is a direct swap, and that I'm not going to need to hunt for or modify drive shafts, or anything else?

Appreciate any info from those in the know

i am doing a 231HD swap right now.... and i am sad 2 say...it is not a 100% percent swap, but that also depends on the year your doner comes from.

the speedo and 4X4 sensors will be need 2 b swaped over.


now i had 2 sawp input gears, but u have a different tranny than i do, so it may b different 4 u. I also yhave 2 get a differnt size yoke for my drive shaft, but my T-case came out of a doge, so it may be different.

good luck.

Thanks for the input.
I think I'm in a slightly different boat, as this is a regular 231j.
The guy I bought this from is a Jeep shop, and seems to know what he's talking about (claims he does a couple of these a month). He claims this is a straight out swap, and the only part I may want to get is the shift bezel indicator that says '2h,4h,n,4l'....other than that I shouldn't need anything.
But this is coming from a guy selling me an item on EBay (although he has an excellent seller rating, and on the phone seems a nice and knowledgable dude). I guess I was just hoping to get independant verification of what he is tellin me

No idea actually what year it's out of. I doubt the guy could even tell me, as it sounds like he has quite the collection of used parts (his EBay store is all jeep, with over 600 items listed).
Here's the item's listing:

231 J transfer case in perfect working condition. Tested thoroughly before being pulled. Has no leaks, makes no noises, and shifted flawlessly. Has 23-spline input. About 92,000 miles on it. Fits all Grand Cherokees 93-95; 6 cylinder, standard Wranglers 91-95; automatic Cherokees 91-95; and 6 cylinder, standard Cherokees 90-95.
So, hopefully it'll be what I need when it gets here...

Well, it finally arrived! Apparently they 'forgot' to ship it out. After 3 days of calling and emailing them last week, they finally gave me a tracking#, which indicated it was shipped on the 24th (10 days after I purchased it). Well, better late than never I suppose

Lookin good so far. Actually has the proper front yoke and rear housing. Measuring it's overall length, it's the same as the 249 I'll be pulling out, so shouldn't need to mess with drive shafts. Only question left is the input shaft...obviously won't know that one till I pull the 249 out, but the mfg date on the 231 case tag puts it very close to the right age, so i'm hoping I get away without having to swap inputs...we'll find out soon enough

Welp, it's in and running

Input shaft was a match (yay, didnt have to tear the cases apart), ft yoke was a match, old drive shafts fit right in without having to lengthen/shorten either one.
Got a couple stripped bolts to deal with, but all in all it wasn't too painful.

It did come with the wrong indicator switch, so currently the VIC isn't telling me anything, but the wrecking yard I bought it from says they're gonna send me the right switch...

congrats on the swap....I went with a 242 and love that I made the decision to swap before my 249 went bad. I still have a good 249 though. Wondering if I should put it in the dumpster...or what.

My 249 is a paperwieght.
The fluid I drained from it had all sorts of metal shavings in it
It will be in the dumpster for next weeks trash pickup.

I am attempting the same thing as we speak as soon as I can verify that the one that I am in the process of buying will work. Does anyone know if a 231amc out of a Comanche will work?
