The reduction of powertrain noise, vibration and harshness (NVH) in modern vehicles resulted in unmasking other NVH issues and concerns in the vehicle. One of these concerns is driveline NVH. Driveline NVH is one of the customer complaints that appear in various forms including warranty. One of the main issue that drive this phenomenon is vehicle to vehicle variability. This is driven mainly by the variability of driveline imblance from one vehicle to the next as well as the variability of vehicle sensitivity to imbalance from vehicle to vehicle. One of the key reasons for such variability is the axle mounts themselves. This paper addresses the issue of variability, and robustness, of axle mount system to driveline NVH.
