Abstract
A resilient rear suspension for graders for creating an impedance mismatched to attenuate the noise transmitted from the drive gears to the operator's compartment. A resilient elastomeric material is interposed between the axle housing and the suspension trunnion attached to the vehicle. The rear suspension further employs a backing ring to increase fore, aft and lateral stability of the axle with respect to the vehicle frame.
