Excessive vibration at high speeds on a Ford E-350 despite road force balancing of tires could be caused by issues such as wheel alignment problems, worn suspension components, or a problem with the driveshaft. It is recommended to have a qualified mechanic inspect the vehicle to diagnose and address the root cause of the vibration.
