Most likely a slightly mis-aligned prop shaft.  The centre mounting should be 
shimmed using a special jig to get the prop shaft exactly in line - at 140k the 
odds are pretty good that someone has had the thing out and put it back 
without re-aligning it.  If you don't fix it, it'll just carry on rumbling for 
the next 140k miles.
 
If you decide not to fix it - make sure you check the centre universal joint, 
roughly under the centre of the car.  Sometimes there's a grease nipple in the 
centre of the universal joint.

All quattros are accomplished ventriloquists.
