It features a high 45-degree maximum joint angle, making it suitable for applications that require greater articulation, such as off-road or severe-duty conditions. The slip yoke slides on the transmission or axle output shaft to allow length changes as the suspension moves. It should be replaced when the splines wear, the U-joint bearing seats become damaged, or if the yoke develops excessive play.
