We have both tried new tires no change, I have had alignment done twice at my work We used Mustang 2 Settings. We both have Rack and Pinion Manual Steering Racks, my Uncle has just changed his to a manual, Had same problem before. It doesnt Shake all the time on Newly Paved roads it doesn't shake very much some times not at all. My uncle Replace his Shocks with new ones and didn't make a change. ONe other Thing Neither of Us have vibration reducers in our steering Shafts Will they make a difference. My dads 39 has a mustang 2 front end and doesn't have a vibration reducer but he gets no shake. Any more ideas!
