ABSTRACT:
A mass damper for use with a drive shaft center support bearing is located on a non-rotating portion of the bearing and is suspended on a spring element for free vibration and has a resonance that is selected to be the same as that which would otherwise be communicated to the vehicle through the bearing by the drive shaft and drivetrain components. The two embodiments are each tunable so that the damper can be set to have different resonant vibration characteristics, as required for use with different drive shaft and drivetrain configurations.
