Suicide front axle was a term used to define a suspension configuration used on early Ford cars.[1]
The configuration consists of a one-piece axle, to the ends of which the steerable front wheels are mounted. The axle receives its vertical support from a transverse leaf spring, and its horizontal support from fore-aft links (usually called "wishbones") which are attached (via pivots) to the ends of the axle at their forward end and to the sides of the chassis (again via pivots) at their aft end. The ends of the transverse leaf spring can either tie to the top of the wishbones, or to the top of the solid axle. The transverse leaf spring is supported at its center by a pivot or link on the center of the chassis's front crossmember.
