Checked drive shaft, thought might have lost balance weight, every thing OK. I had the dealer do the brakes, this vibration only occoures while drivung nothig while stopping. I have checked all things I know of, next thing is to go to dealer. It's strange,it has me puzzeled. Thought maybe some one there could come up with some thing in regards to center line vibration, thought it could be the vibration damper NOT.
