A dust boot retention system includes a jounce bumper having an end portion with an outer diameter and an annular recessed groove adjacent to the end portion. A dust boot is attached to the jounce bumper and has an upper flange including a radially inwardly extending portion and an axially extending portion extending from an innermost portion of the radially inwardly extending portion. The axially extending portion has an inner diameter smaller than the outer diameter of the end portion of the jounce bumper. A rate ring secures the dust boot to the jounce bumper. The rate ring includes an inner diameter smaller than the outer diameter of the end portion of the jounce bumper. The rate ring includes an annular recessed channel in a first end thereof for receiving the axially extending portion of the dust boot. The rate ring and the upper flange are press fit over the end portion of the jounce bumper whereby the rate ring is received in the annular recessed groove and secures the end portion of the dust boot to the jounce bumper.

A suspension system for use in a laundry washing machine to suspend a tub assembly from a base portion of a cabinet. The suspension system includes a support frame interconnected to an outer tub of the tub assembly and an isolation damper assembly for resiliently coupling the support frame to the base portion of the cabinet. The isolation damper assembly functions to allow limited lateral movement of the tub assembly relative to the cabinet while also providing a 'return to center' feature. The isolation damper assembly is further operable to prevent rotation of the outer tub relative to the cabinet. Finally, the isolation damper assembly functions to absorb the vibration transmitted through the tub assembly to the support frame so as to minimize transmission of such vibration to the cabinet.
