Changing from 242j to a 231 transfer case (Kinda emergancy)

Here's the story, me and the girl friend split, and she agreed to go quietly if I gave up one of my vehicles (It was that or the home) and so I am gonna give up the Jeep. It needs a Transfer case though before it will roll away, so here I am asking questions. (I am keeping my damn bumper and off-road tires though)

The 242 is about $300 in Washington, and that's more than I had planned on spending. Since it just has to be drivable, and the 231 is half the price, what do I have to do to convert?

1990 Jeep Cherokee 4.0 auto

I just want her out of my life, with all the money I will have now, I will go get another project jeep for $500 in two weeks. Lol.

Swap it in? I think the drivelines are all the same except for spline count. The shifter detents in the cab may be different, but just to get it rolling, leave it in 2HI and don't connect the linkage.....

I may be wrong but I think the rear ds lengths are different. Probably not different enough for a taillight warranty though LOL. Good luck!

So you are all rather sure that it will bolt up to the transmission, and the front Drive shaft, but not so sure about the rear drive-shaft length? That is perfect since I am putting a new drive shaft in her any way!

Will the linkage be able to function even if it looks less correct?

Thanks so much yall, the sooner I get this thing gone, the sooner I can ignore her.

i do know that the 90 cherokee has a 21 spline count for the input gear so at least make sure that the 231 has 2 spline. as for 4wd linkage i think its the same if not you just need to remove the bolt and turn the tab the linkage is on

The gating in the shifter assy is different between the 231 and 242 and I thought the length of the lever was different to accomodate the longer stroke of the 242 range.

I have swapped a 242 in place of a 231 and everything bolted back up just like it came out, driveshafts are the same and all the spline counts are the same AS LONG AS the xfer case being swapped in is from a 4.0

I left my old gate on the floorboard, and sold the jeep like it was.

This must have been like a 10yr girlfriend for her to think she gets the house or a RIG.

At any rate...the 231 will swap right in.

And an even bigger "emergancy" is learning how to spell emergEncy.

so wait...she wanted a $2k jeep over a house? What is the house, a cardboard box behind walmart?

Make sure you try to get a similar year cause I know that the spline counts changed at some point

its a $800 rig to be honest, and she wanted to keep the apartment, but since she has no job, no life, and no idea how to take care of her self, i said no. Its just easier that way.

Thanks yall!

Sorry to say this but if you're not married, kick her to the curb. My divorce cost me $100,000 to get her to walk away but she owned half the house/cars.
