Abstract

An integrally cast aluminum subframe for a vehicle suspension system has control arm connections that avoid high stress in the connections. Mounting studs may be an integral part of the subframe casting or may be subsequently joined to the subframe. Bushings of the articulations of the control arms are joined to the mounting studs from one side only, so that the flexing of the connection that was present in the prior art clevis connection is avoided. Consequently, the articulation is retained between a head of the mounting bolt and the mounting stud.
