NG900's do not always vibrate but they are very sensitive to any problems with the suspension. When everything is right, they are smooth at all speeds. Possibilities, in rough order of occurrence - - out of balance wheels / tires - bent wheel(s) - bad tires - outer control arm bushings worn (typically only vibrates under acceleration but there are exception) - inner driver(s) worn (again, mostly under acceleration) - stanchion arm bushings worn - brake problem causing shimmy (most brake problems only occur when braking, typically at higher speeds). - CV joint (typically has other common CV joint symptoms) - subframe loose - loose steering rack mounts Unless the problems are only under braking, have the wheels and tires balanced on a Hunter GSP700. It doesn't matter if you had them done by a top-notch wheel guy - unless it feels perfect after that, you need to get the road force balance done on a GSP9700. Costs no more than other balancing and there _is_ a difference. Trust me. http://www.gsp9700.com to find one near you. The GSP9700 will not only fix any balance issue that can be fixed, but it will give you specs on wheel trueness and out-of-round. It will also give you numbers on the tire's problems (uneven road force). If you have problems after that, post again with most specific e.g. only under acceleration, braking, etc.
