My AWD Ghia is very quiet at a 110km/h.
I have recently had roof bars installed, and this has given the Terri a noise at 115km/h but it is only just audible.
An out of balance tail shaft should show up as a vibration, not a noise.
The shafts are balanced on the vehicle at the factory check the shaft, you should se balance weights clipped on. Compare it to another Territory.
The way you describe it, the vehicle must sound like a 1950’s jeep. The Auto’s do not make that much noise even on their last legs (when planetary gear set has failed).
Could be the transfer case, I read a report about how BMW found & rectified a balance problem in the X5 transfer case (NV125, same model as Territory).
http://www.wcs-group.com/ecs526/Group2Final.ppt this is the document in Power Point. The problem only occurred at high speeds on the Autobahn.
Here is a NVH testing facility for the transfer case

I have come across seized tail shaft universal joints & CV joints that make a hell of a lot of noise, but usually vibration accompanies it.
The Territory does not use universal joints.
Could it be the differential making the fire siren noise?
Has the mechanic pinpointed where the noise is coming from?
I mean did they specify a position e.g. rear centre, rear right, etc?
If they think it is the tail shaft, what is the problem? The vehicle is under warranty, give it to them & get a loan Terri while they fix it.
Let us know what happens.
