A method is disclosed for providing a tuned mass damper for a powertrain component. The method includes the steps of providing a mount adapted to be attached to the powertrain component; assembling a mass element to the mount; and molding an elastomeric body around the mass element to bond the mass element to the mount. The tuned mass damper assembly for a drivetrain component is also disclosed that may be attached to a mount having an opening that extends through the mount or a housing portion provided on the mount The molded elastomeric body integrally attaches the mass element to the mount. Alternatively, the tuned mass assembly may be bonded to a plate that is attached to a motor retention element.
