Deceleration Growl. With A-10 strafing video!

The Jeep:
246K mile 1999 XJ 6.5" lift, stock rear shaft with shims. This will be a SYE/Tom Woods eventually.

Symptom:
When I let off the gas I get a growl. It sounds like an A-10 firing it's cannon.


I can feel it slightly in the steering wheel, not at all through the seat suggesting a front end issue. It does not do it every time.
It will do it decelerating from any speed over 25mph.

If I turn my wheels mid growl it does not effect the sound.
Three point turns do not elicit any ticking or popping

With my hand on the T case handle, I do not feel a pronounced vibe through the handle when it happens.

Stuff I've fixed so far.
*New rear U joints
*New front U joints on a newer driveshaft
*Fixed exhaust hangers.
*Tcase fluids. (they were BLACK)

Trouble shooting employed so far:
*Jacked up both ends of the Jeep and spun the wheels.
No noticeable noise present in either diff
*No leaks at pinions
*No hand-play on either pinion

Up next today:
Diff fluid changes and examine wheel hubs

Any thoughts?
