shaken, not stirred
I have a 2004 Ford E-250 Cargo Van I use for work. It has about 285k on it. I drive all over the country with it. That being said, while cruising anywhere from 45-60 mph the steering wheel vibrates for about 8 seconds and then stops for 8 seconds, then repeats. Any clue??? If I am on the interstate 60+ mph its not really noticable at all. Any thougths would be appreciated.
