I would install the 242, then test the driveshaft length. There have been several people who did not have to shorten. You might be one of the lucky ones.

Yeah I have the upcountry suspension I dont know if thats a factor. But yeah thats my plan. Install transfer case first day im off work. Then if I had to shorten it it gives me an extra day were I don't need my jeep.

When i did my 242 swap on my 5.9 i did not have to do anything with the rear shaft. I have about 1" before it bottoms out. Keep in mind im at stock ride height and i never wheel it. Daily drving the shaft only moves about 1/4" in either direction.

I'm getting ready to swap my 249 TC from my 94 5.2 with a 242 TC from a 98 I6 in a couple of weeks. I have 3.5" of lift and was wanting to confirm if I was going to have to do anything to the rear DS. If I have read everything right, I think that I have to use the front half of my 249 with the rear half of the 242. Just wanting to know if I was missing anything. Thanks guys.

Its hard to say for sure until you actually do it. Your 242 should have the external slip yoke, which is longer, but the 3.5 inch lift should make up for that.

I have a 2" lift and swapped my case to one with an external slip, i only needed around 1/2" taken off my ds to make it work. (i had them shorten it 2" but could have gotten away with 1/2-1")

Well my swap went great thanks to you guys. 249 97 to 242 97. Everyrhing bolting up perfect. Now just gotta shorten driveshaft about an inch.
Didn't think my other tc was so bad. Drained the fluid, and there was rubber shavings in the the fluid.

So far i have 2 swaps done and here are my results

1998 ZJ 5.9 shock height 242 out of a 96 ZJ 4.0 direct swap no need to shorten the driveshaft. It NEVER gets wheeled, street Jeep only

1997 ZJ 5.2 lifted 4.5" 242 out of a 97 ZJ 4.0 direct swap no need to shorted the driveshaft. I have more than enough room to flex with out bottoming anything out.

I think you guys shortening the shafts feel the yoke slips more than it actually does. The driveshaft moves very very little in either direction unless you compress the suspension to the bump stops on both sides in the rear at the same time which is not going to happen unless you jump it. Im going to get pictures of both my ZJ's tomorrow showing the yoke at the transfer case. Would be cool for you guys to do the same just to see where everyone is at.

Mine had to be shortened 'cause with it 100% bottomed out it was still too long to even fit under mine. I had it brought down two inches, so I have about 1 1/2" travel both ways. You can't really see it in the picture I just took 'cause of the boot though. haha

I was thinking of shortening mine 1.5inch. The way it is now. I cant get it to even bolt on. It needs to be 1/4 in short just to get it to slide into the ujoint. And thats with it 100 percent on the yoke. So Im thinking 1.5inch short will be a good measure. I dont offroad or anything

I really dont understand why some of us have no reason to shorten the driveshafts yet others do? Just doesnt make sense.

Yeah it is definitely odd. 5.9s dont have tk shorten. But 5.2 its a 50/50 chance.

That's exactly how mine was, so yeah you should be fine with 1.5 inches.

Well it's because of all of the different variables.

93-95 had longer transmissions and all had the dana 35 rear.

96-98 5.2's had shorter transmissions, but longer rear axle pinion; the dana 44a.

96-98 4.0 had different transmission (I think shorter than 93-95) and had the dana 35 rear. So these had longer driveshaft then the 96-98 5.2s.

Then you've got the 98 5.9, which I think has a different transmssion even then the 96-98 5.2.

On top of that, depending what case you swap in will make a difference, after 96 (I believe) Jeep transfer cases starting coming with an external slip yoke, which was 1.5 inches longer than their internal slip yoke counterparts.

Then you have the fact that most guys on here have lifts on their jeeps, anywhere from 1" to 5", and in some cases even higher. So basically, there are just too many variables to be able to determine unless you just do the swap and find out for yourself.
