Was up at the barn with my tape, (wind blew part of the roof off, now there is snow in there). I measured the free-play on that one there. About dead on 5/16 of an inch right at that 3 3/4 in. flange. I got it out of a Jeep that had burnt 10 years ago is all I know about it.

Get all four wheels off the ground, leave your jeep off, put the trans in neutral and the tcase in 4hi, take the driveshaft out and try to turn the front output back and forth while comparing its movement to the rear output. You might still have the same problem with the new tcase...dunno.

Yea, I'm talking about basically the same thing. This one, with no front shaft on it, when I rotate the front output, (which has the sprocket right there), it rotates free 5/16 of an inch, (back and forth). I'm feeling the play in the chain there. I measured that right on the 3 3/4" dia. output flange.
Actually it might have been siting there closer to 15 years. Roof is fixed! Btw.

I know you are sure the noise is coming from the T-case, but what if it's not?
The marbles sound you describe, sounds to me just like the sound of a broken core in a catalytic converter. The core is made of ceramic honeycomb, and sometimes a hot spot develops. This can cause pieces to break off inside the cat.
Sometimes these work their way out the exhaust outlet. Sometimes that takes weeks to happen, then the next chunk breaks off.
If you get a length of garden hose about 3 foot long, you can use it like a stethoscope to pinpoint the source of the noise.
