anybody ever heard this noise?

This is a ZJ but I post in the XJ forum because it's an AX15e and NP231 from a 94 XJ.
Here's a link to the video..

Happens only in 1-3 from what I've seen. I'm ruling out clutch/hydraulics for now since they're all new. Looking more towards my junkyard bought AX15 and 231

Hard to really make on my tiny laptop speakers, but sounds to me, like chain in your np231 is scraping the casing.

Not going to lie sort of glad to hear that as a second opinion. I've never had to do any work on a t case. Would this be cause by a worn chain or could the planetary gears be causeing this too? Before I installed the t case I split it to change out the Input shaft so it would work w my AX15. Everything seemed nice and tight with minimal play so I assumed it would be fine.

Anybody have anything on the whirring noise and wobbling noise that is only present with the clutch engaged?

I'm not an expert, so take my thoughts with a grain of salt, but it sure sounds like the chain rubbing to me. The only way that I know of to check, is to open it up and see if there are rub marks on the case. I'm not sure if you'd get that sound from bad gears... To me, and again, I'm listening on my laptop so its a little hard to make out the sounds, but it sure sounds like the chain to me, and not the grinding I would expect from a gear.

I'll take another listen with some headphones when I get a chance, but someone else will probably chime in by then.

Put the transfer case in nuetral, then run it threw the gears if it's quite is look at the tcase. It's not a guarantee, the noise could depend on load

Mines doing that. I thinks its either the chain or shift fork.
I'm rebuilding mine this week with the wider chain and 6 planetary.

Tried that as well as tcase in 4x4 and 2wd on Jack's. Couldn't get it to happen. I talked to my cousin who's an experienced mechanic, he said a retaining clip or c clip in side the t case may have come loose or broke and the shift fork "tries to shift" when vibrated. As for these other strange sounds, I have determined bad bearings in the trans. So looks like I'm dropping this again for the 3rd time to rebuild.
