ABSTRACT:
A slip joint includes a slip shaft having a plurality of axially extending grooves, and a slip yoke having a plurality of axially extending grooves. The slip yoke is in telescoping engagement with the slip shaft, and the grooves formed in the slip shaft are circumferentially aligned with the grooves formed in the slip yoke. A plurality of torque transmitting balls is disposed in the grooves. A helically shaped cage is positioned radially between the slip shaft and the slip yoke. The cage secures the balls to maintain the balls spaced apart from one another and within the grooves.
