ABSTRACT:
A vehicle suspension control arm (10) is formed as a single, homogeneous unit of metal material in the configuration of an elongated tube (30). The tube (30) has first and second pairs of opposed openings (68, 68; 80, 80) defining first and second passages (72, 82) which are sized to receive first and second pivotal joint structures (20, 22), respectively. The first and second passages (72, 82) extend transversely through first and second hydroformed sections (40, 42) of the tube (30).
