Abstract
An elastomeric bushing comprises an inner sleeve including a first end face and an opposite second end face. An elastomeric bumper is disposed around and directly engages the inner sleeve. The elastomeric bumper includes an annular void. An outer sleeve is disposed around the inner sleeve and the elastomeric bumper, spaced apart from the inner sleeve, and directly engages the elastomeric bumper. A one-piece monolithic ferrule includes a cylindrical sidewall surrounding a portion of the inner sleeve, an end wall, and a collar. The end wall radially inwardly extends from the side wall and overlaps the first end face of the inner sleeve. The collar has an outer surface positioned within the outer sleeve and within the annular void to limit the radial extent of relative movement between the inner and outer sleeves.
