had it on a hoist and couldn't replicate the noise.....seems everything needs to be under some load to get it to happen.

I thought rear diff issues were a side effct of dccd? (non dccd box here)

Centre diff?

I've heard the v6 sti boxes may have had a thrust bearing issue also?

Not rear diff as it seems to eminate centrally in the car i.e. from the box or front end.
