So I am waiting to find a 242 shift tab, but my Jeep still makes a noise that I'm guessing is coming from the tcase, though I can't be sure.
The car makes no obviously bad noises until I reach 35mph, then there's a vibration noise that sounds speed dependent that doesn't go away again until I get all the way down to ~2mph or if I put the car in Neutral. Does anyone know what that could be? I removed my from drive shaft as per someone else's suggestion, but it didn't help.
Ok, so I was getting my 242 cleaned up and ready for new seals before swapping it in this weekend. I noticed something that kind of concerns me, I can turn the two driveshaft outputs independent of each other, regardless of shift selector position. I can turn either output individually and it will spin the other one, albeit very slowly.
Is this normal?

Sounds like really bad bearings, no fluid, or a bad planetary set.
I'm on my phone and its inconvenient to look back while typing a post. What year case is that? Input swap?
Edit: looking back, you've got a bad case and it needs the rest of the rebuild. Chain, bearings, seals, etc. Verify year by the tag.
Do you think it could be the planetary set? There was more play than I would expect when I took it apart, but it didn't seem like the gears were worn. Are they made with quite a bit of play?
I'm perfectly happy to do the rebuild, I just want to make sure it's not something like the planetary set or a worn gear that's catching up to itself. When I looked, there were no teeth missing or anything.
The tcase is a 97 242, I didn't need to switch inputs, but I did anyways since the 249 had a nicer one.
I have a quick question for you guys. I had been looking into 242s but I just found a 231 for a decent price that I could get.
I have a 98 4.0 42re and 249 stock. I have a .840" input on my 249 case.
The 231 is out of a 93-94 ZJ with 4.0 42re and the thread says .840" inputs on these cases as well and looks like it in the picture to me too.
If both cases are ISY and have the 23 spline .840" input would it be a direct swap into my ZJ? (Not requiring driveshaft shortening or input, front case half, and planetary gear swap.)
If the inputs are the same length and spline counts the same on both tcases, but turned out to be earlier gear cut would it even matter to me? Would I need to swap the inputs, front case and planetarys for length and spline counts? Or is there some other issue with the gear cuts I dont know about? Im under the impression you would only need to swap the front case half and planetarys when you need to swap the input over between cases with different gear cuts. Is this correct?
I know all these questions probably have been asked and answered in this thread already but I am looking for a quick answer from the knowledgable members here.
edit: ok I found this but am confused on what the collar is this is referring to
"One other issue I've run into: 93-95 ZJ 231 and 242's with the .840 input have a metal collar pressed into the input shaft that mates to the bevel at the end of the transmission output shaft. 96+ transmissions do not have this bevel, meaning it is required to remove the input and either swap it, or you can easily take a deep well socket and tap the collar out along with the main shaft bearing. Reinstall the main shaft bearing into the input, making sure it is fully seated and that is the extent of the fix."
