Like the title states. Anybody figure this out yet? Every post/thread I see with the 65-75mph vibration ends inconclusivley!

Yes, it's an out of balance driveshaft. You'll need to take it to the dealer and they will have to send it off to have it balanced. It makes all the difference in the world.

If you have the vibration get it fixed, or take the risk of dropping your driveshaft like MikeP and I did. :( But its all better now :)

Anyone know a dealer in the MA area that I can go to and have this fixed? My dealer always tells me they can't reproduce my problems and their "fixes" for stuff are half-assed.

how long of a wait to have the Drive shaft rebalanced?

Mine took 2 weeks. Not sure of the wait now.
