IME the rubber mounts do allow some motion of the prop shaft.  The prop
shaft is supposed to be balanced and co-linear ... if this is all true 
then there should be nothing to shake.  If you rotate the prop shaft and 
look between the "arms" of the u-joint you will see a standard grease fitting
(zerk (sp?)).  Service interval is 15K miles.  

Wish I had more to suggest on your problem ... you might want to have some-
one hang out the door while the car is moving to try to find the source ...
