Abstract
A half round end yoke includes a pair of opposed arms, each terminating in an end surface having a recess and a pair of threaded bores. A cross includes a central body portion having four trunnions extending outwardly therefrom. A bearing cup is rotatably mounted on the end of each of the trunnions. The cross is initially positioned adjacent to the half round end yoke such that a pair of the bearing cups is received in the recesses formed in the arms. Then, a retainer strap is positioned adjacent to the cross and the half round end yoke. The retainer strap includes an elongated central body portion having a pair of transversely extending retainer portions. Each of the retainer portions includes a curved region having a pair of end regions extending outwardly therefrom. Each of the curved regions has an inner surface formed therein. The inner surfaces of the curved regions of the retainer strap receive portions of the bearing cups therein. The end regions of the retainer portions have respective holes formed therethrough that are sized to be aligned with threaded bores formed in the arms of the half round end yoke. Threaded bolts can then extend through the holes formed through the …
