The cv joint could be bad (the one on my 90Q went on me).  Also, the 
center bearing must be aligned properly (propshaft dead straight, as I 
recall).

Of course, it could be any number of worn/loose driveline parts 
transmitting their noise back to that location.

A bad cv joint will probably exhibit some "incorrect" play, ie up/down 
or left/right movement.

You need to get under the car and give all these things a good push and 
shove around to see what gives.
