I have a vibration noise coming from the passenger side on my 1992 chevy lumina van. It did it for a brief couple seconds when turning right and than stopped and than about fifteen minutes later
and again at a stop light going about 15mph, the first time going around the corner I was only going about 20. It sounded like when you hit the ribbets on the side of the highway to let you know you went over to far..what could this be.
