My 2003 Impreza Outback Sport automatic starts to vibrate ...just slightly... approaching 70mph. The vibration is cyclical: it lasts for about
3 seconds, then stops for about 2 seconds, then vibrates again for another 3 seconds, and so on. I can feel it in the steering wheel. I had a wheel alignment done but the vibration is still there. It has happened on three or four different highways and road surfaces. The A/C is off. What causes such a cyclical vibration? Thanks Xavo- posted
