09 focus vibrates around 55 mph
My girlfriend has an 09 focus and lately she has noticed that at around 55 mph the car will vibrate in the front end. It doesn't happen all the time though. I thought it might have been the engine just acting a little rough at that rpm so i turned off overdrive but it still vibrated. I was thinking maybe the tires are a little off balanced or they put the weights in the wrong spot on the wheels, but wouldn't they shake all the time then? Anyone have any ideas what it could be?
