At 4" you might be able to use your original shaft.
The donor shaft will not be the correct le ngth due to the difference on transmission lengths between v8 & i6 and the different lengths of the 44a & d35 pinions. If you have an i6 you can use the donor shaft.
Cutting down the output or the the slip yoke leads to less than ideal engagement and possible imbalance.

I'm almost banking on my longer control arms allowing me to use my stock shaft. Otherwise, I'll be using the 249 for a while longer. My wife won't be too happy with me if I have to spend more money on my Jeep.

A 93 - 95 V8 ZJ should have a shorter rear DS, although I don't know if it's the correct length. The D35 is shorter than the 44a, but the 46RH is a few inches longer than a 44RE or 46RE.

Will a 231 from a 97 TJ with an AX5 work in my 97 ZJ 5.2?

Welp, I found out what was wrong with the t-case I got.

You guys lied that 242s last forever, lol. A pin is missing on the differential gearset, and in it's place is a really non-concentric hole...Any ideas? I guess I just have to get a replacement?

You've been put through the ringer a little with this TC, "luck of the JY draw" I guess.

So, where is the pin missing from?

[Edit]

Wait, I see it (I was previously on my phone).

[Edit 2]
Craigslist. "luck of the craigslist draw"

All the 242's I've dealt with had at least a stretched chain.
They really don't last that long. But I've never seen a planetary set that bad.

What are common symptoms of a stretched chain? Can you tell without opening up the case when it's not installed? My case has all new seals on it from the PO. It also came out of a 96 but the case is a 98. Obviously the PO of the JY ZJ swapped it at some point. I'm thinking he overhauled the case before it went in.

by the time you hear it, it has already started eating through the case.

I figured that. But other than opening it up, I'm going assume there isn't a way to tell if it's stretched?

Do you think I should just get a whole other tcase? Pick n pulls in my area sell them for ~$165, or I can get that planetary set for ~$65 on ebay. If the planetary set was that bad, do you think that there was something else wrong with it too?

I have a 96 zj, 5.2, 44RE, D44a, NP249. I want to swap in a NP242 as they are plentiful in my area. I realise that i have ISY and the 242 will have ESY. Now i have been reading through this thread and some people say its still a direct swap using my original rear driveshaft, others say i would need the rear driveshaft from the donor vehicle, and i also read that i would need to have my driveshaft shortened and balanced. So what is it? I just want to know what im getting into and have all necessary parts before i go and tear the jeep apart as i drive it daily.

I've come to this conclusion: it's a Jeep.

That about sums it up. Everyone has different experiences with them when doing the same mods. Some people need things others don't while those same people don't need things that the other people did. The mid 90s really emphasizes Chrysler at its finest. And don't take that in a negative way. I love my ZJ.
