Try the taxi tests with wheel pants off. If that eliminates the vibration try to reduce pant weight, especially aft of the axle. The pant attachment should be quite rigid, is it? As a last resort try adding some weight to the nose of the pant. What was the tire wear like on previous sets? Are the gear legs crack free and rigidly attached to the airframe? You could try a different brake pad material, just a shot in the dark. Good luck. Regards, Bill Hannahan wfhannahan@yahoo.com _____ Choose the right car based on your needs. Check out Yahoo!
