thats like having a dr perform heart surgery and he doesn't connect the aortic valve

 

Vibration solved. Driveshaft replaced.

 

bump. Does anyone know if there is a tsb on this? How did you convince the dealer? I finally was able to get them to order a new one, but they think I'm a PITA!

 

I just noticed it for the first time yesterday, doing 75 to 80 MPH on the highway. It has gotten fairly cold here in Kansas the past couple of days. I wonder if it had anything to do with that. My first thought was wheel weight or U-joints/driveshaft. I don't drive the car often enough to throw a wheel weight - I avoid potholes and big bumps. I'm thinking driveshaft or something part of it.
