Grumbling from transfer case

Since getting a new set of (quieter) tires, I can hear a grumbling from the midship area while coasting or at very light throttle. The noise gets louder if I engage 4WD. Truck is a 2014 G56 with a BW case.

All the U joints including in the axle are good, I've replaced every one except the front driveshaft.

The noise persists when coasting, with truck OFF and G56 in neutral.

Noise persists when coasting down hill and transfer case is in neutral, trans in neutral.

Can hear when rear is off the ground (front driveshaft not spinning).

If I also pull the rear shaft, the noise stops (weird).

There is a very small amount of play at the tailshaft, nothing I would deem extreme.

After driving 40 miles and then running these tests, the fluid was nice and clean, no shimmer. About a half quart puked out tailshaft housing while running with no driveshaft.

Right now I am considering the chain to be stretched or a broken tailshaft thrust ring, which I found two cases of on here. The backlash on the rear pinion is normal, and I think the noise being louder in 4WD eliminates the rear axle? Any thoughts?

Long overdue update to the issue- broke down case and found nothing wrong.

Local friend/machinist/drivetrain specialist did audio and thermal imaging on the rear axle. Ended up having a bad bearing on the diff carrier. It was impacted pretty bad and had started to chip on the race surface. Rollers were torn up as well.
