Default '02 Bonneville vibration

Good news: My Black Beauty now has over 340K miles on it! My son moved to Utah and now has the car.

Bad news: It has developed a vibration between 45 and 50 MPH, felt mainly in the floor. (Also, a less noticeable vibration at around half that speed)

The tires have been replaced and he had them re-balanced/rotated several times. It was suggested that a hub assy was bad. He replaced it: No help.

He then discovered two busted motor-mounts. Has to be the problem, right?
Nope. He replaced them and it still does it.

Any ideas?

PS- No more Bonneville coverage on this site ?????

All aspects of the front end checked? Was an alignment done? Should be done after tire replacement....
