A friend of mine's 90 N/A had a real slight vibration as in like when the steady bearing sags. He changed it out for a new one and now it vibrated horribly starting at 30 mph and gets so bad it would probably break Kidney stones down if you had any. He next had the U joints changed and it's exactly the same. Ideas?
