Abstract
A leaf spring for a vehicle. The vehicle has a drivetrain that generates a high frequency vibration that is transmitted into an interior compartment of the vehicle and has a volume that can be heard by a driver and/or passenger. The leaf spring has a primary leaf and a secondary leaf that extends along and underneath the primary leaf. The leaf spring also has a high frequency dampener that is located between the primary and secondary leafs and is spaced apart from a tip liner insert. The high frequency dampener reduces the volume of a high frequency vibration that is present in the interior of the vehicle to a value less than an objectionable level to an occupant during operation of the vehicle. Therefore, the high frequency vibration is not heard by the driver and/or occupant.
