A spider or cross for a universal joint is manufactured by first forging the basic configuration of the cross and thereafter extruding the trunnions into their final configuration. The component is initially hot or warm forged into its basic configuration including a central body and a plurality of trunnions. Thereafter, the trunnions are simultaneously extruded into their final configuration eliminating machining and a loss of materials. As a result, the grain flow of the component is not disrupted for a more reliable part. |
