Ok I'm sure y'all are tired of getting asked this I tried to skim threw the old post and learn what I could. If I'm understanding this right I have a 98 zj and anything from a 96 to 98 will work for the 249 to a 242 swap and its a direct swap except I might have to use a shorter drive shaft is this correct?

Thanks for the quick reply!! One more question. Will the one that would be with that transfer case(if I can find one together) work?

The DS that comes with the t-case will likely also be too long, as a 4.0 would have a D35 rear axle (your 5.2 has a D44a, which is longer than the D35). If you have an alternate method of transport, I'd see how it lines up with your current shaft, and if it's too long, then take it to a driveline shop and have them shorten it an inch or so.

I bought a 231 off eBay for 150 bucks. It's out of a 98 Cherokee. Can't wait to get her in. She took a bit of damage on her way to my house but its easily fixed. Yee Haw...2WD!!!

Nice score on the xfer case, too bad the monkeys who delivered it couldnt resist throwing at your front door while driving by at 30mph

What's the difference in a 242 and a 242j? So places list both so I'm assuming they are 2 different things.

242 and 242J should be the same, but some WJs got 242HD. So, if you can get a 242 from a 96, 97, or 98 ZJ you'll be in good shape.

2002 to 1998?

Hey guys,

I recently picked up a 1998 limited with a bad transfer case hoping to fix it up and learn something while I did it. I took out the xcase and ripped it apart and it looks like it's the VC (obviously) that's bad since nothing else seems to have any damage.

I've been reading this thread, and others, and I've decided the cheapest way for me to get this car rolling (other than taking out the front drive shaft) is to get a 242.

Does anyone know if I can use a 242 from a 2002 Grand Cherokee and stick it in my 98? I'm willing to do the input shaft switcharoo...I've dug around, but I couldn't find much information about the 2002 242's.

*edit* Okay! Well, cancel that. There seems to be a lot of information about this, I just have to use WJ and XJ instead of the years:-D. Hehhh...sorry. Ignore!

I'm thinking about hacking 1" off my output shaft instead of shortening the driveshaft.


Anyone have a problem with that?

I cut mine, but don't do more than a 1/2". Any more than that, and it's the outside of the piece of the driveshaft that's what hits, so you'll gain nothing from cutting more.

^this

The yoke will most probably hit the oil slinger on the tail piece, if not you should be OK.

Yep. With the shaft un-cut, it'll bottom out with about 3/8 to 1/2 inch of clearance to the slinger. Cutting it gives you that little bit of extra travel.
