This cross joint transmits torque through the PTO driveline, connecting the output shaft of the transmission to the input of the implement shaft. It sits at the universal joint position, allowing angular misalignment between the two rotating shafts while maintaining continuous power transfer. The assembly includes four circlips that retain the bearing cups in the yoke bores. A worn cross joint produces driveline vibration and clunking during engagement or load changes. The original manufacturer machines the trunnion journals to the same diameter and surface finish as the factory assembly, so the bearing cups seat without shimming. When replacing, inspect the yoke bores for galling and replace the circlips with the included ones.
