Hi gang,
My recently acquired '08 CTT has a peculiar vibration. I *think* it's in the drivetrain, but sometimes I'm not 100% sure. Here's the symptoms:
1) Worse when it's cold
2) Vibration resonates through the body under partial load (kinda like if you have the sunroof too far open with no windows open)
3) If you press harder on the accelerator, it will go away
4) If you put the car in neutral while it's happening, sometimes it goes away, other times not![Confused](https://rennlist.com/forums/images/smilies/confused.gif)
I asked the dealer to check the center bearing, and they said it was fine. Could it be roadforce balance issues from the rear tires potentially? I didn't have my usual place install the tires, the selling dealer did.
Any other thoughts?

If your car was an 04 I would say drive shaft, that makes a strange noise, if you say the word wummering 3 times in a row that gives you the pitch of a bad drive shaft.
Badly balanced tires can also make some strange noises, especially when they are worn and the sidewalls are not as rigid.
What kind of tires are you running and how many miles on them ?
