  • Patent number: 10920844
    Abstract: A bushing assembly for use in a vehicle suspension system includes an outer sleeve, with an elastomeric element at least partially positioned within the outer sleeve. An inner sleeve is at least partially positioned within the elastomeric element, while a bar pin having a central section is at least partially positioned within the inner sleeve. A retaining ring is positioned at or adjacent to a first end of the central section of the bar pin and at least partially within the outer sleeve. The retaining ring is positioned between the inner sleeve and at least one radially enlarged section at the first end of the central section of the bar pin and/or at least one radially inwardly directed section at a first end of the outer sleeve.
