Toyota Repair: vibration, michelin tires, vibration problem

Question
I have a vibration in my 2002 Toyota Sequoia between 65-72 mph. It has new Michelin tires which have been rotated and balnce twice trying to correct the vibration problem but to no avail. The brakes were also checked by the Toyota dealer and the rotors turned. I still have the vibration between 65-72 mph. Can my drive shaft be out of balance? The vehicle has 82,000 miles.
Thank you.

Answer
Yes that is a possible cause, not so much that the driveshaft is out of balance but there may be a problem with one of the universal joints so have it checked for this, keep in mind that a tire out of balance conditon is of kind of a low fequency and is normaly felt in the steering wheel, a driveshaft vibration is much harsher and of a higher frequency and will vibrate the entire vehicle.
