Look at the side of the case on the inside to see if you chain is hitting the case

No, the chain is continuously moving, it makes a rattling, rubbing, train on tracks, can full of marbles, dragging, whirring noise.

Eventually, while in 4wd, you will hear a loud POP as the chain skips teeth. Give it a try in 4 lo and stomp on it in 1st.

Anyways, I'm not sure it's the transfer case, but from that sound description definitely could be.

The chain is not engaged in 2H, right?

Is the noise like the sound of a rotary blade push type lawn mower?

not really, i mean it might sound like that but honestly it sounds more like train wheels on a track, kinda like a roller coaster in that it gets louder the faster you go.

Sorry, I have a TJ front right shaft. It turns the front driveshaft, turns the second shaft on the transfer case, turns the chain, always.
The gear on the transfer case main shaft is disengaged in 2wd, yes, but the chain will rotate with a TJ shaft.

I easily forget about the CAD axle!

Sounds like a broken ring gear to me.

Wheel bearings should be checked too.

I agree with opening up the transfer case and looking at the chain. It's pretty straight forward to take the back of the case off. Use Permatex black gasket sealer on the case when reinstalling.

Any updates? I am trying to locate a similar sound in my 92. I would describe it as "dull and gravely", and it sounds like it is coming from the drive line. I have a slight leak in the RR wheel seal as well, but my first guess would not be wheel bearing noise. Turning tightly does not change the pitch, only MPH...

Thanks for the input everyone, been lurking a few weeks since I bought my YJ, figured it was time to jump in!

Welcome Jay,
I'm thinking its either in my t case or (hopefully not) my transmission. I went ahead and bout a new t case chain from EAD off road, check em out they have a bunch if cool jeep stuff, after shipping it was about 75 bucks. Which is at the very least competitive with other major outlets such as quadratec. Haven't been able to change it yet due to the fact that when I went to remove my skid plate to get to the t case, I broke 2 bolts and rounded 3 others b4 I finally gave up. Not sure how I'm gonna go about getting them out now but that's a problem for another day. Might try to tackle that this weekend. But I'll e sure to let you know how the whole thing goes and take pics too.
