Introduction
Some vehicles may exhibit a steering flutter condition while driven at approximately 55 - 70 mph. In some cases this concern is caused by a wheel imbalance or RFV (Radial Force Variation) that is out of range. If the tire and wheel assembly is satisfactory a steering control valve preload spring is available to reduce the steering flutter felt through the steering wheel.
