Typically, a vehicle’s powertrain features at least one transmission mount and two or three engine mounts. It’s worth remembering some engine mounts are constructed of solid rubber, but hydraulic engine mounts are far more complex. They feature a hollow central chamber — filled with hydraulic fluid — inside the rubber. This setup provides the dynamic sensitivity necessary when driving in sport mode, for example. Accordingly, the Gates® range includes part numbers for these and other associated components.
As with axles and axle suspension, part failure in this category is related to prevailing weather conditions, vehicle age, driving behavior and the quality of road surfaces. Signs of failure include excessive vibration and driver reports of bumps from the engine bay area, which may indicate engine movement.
