It holds the U-joint cross at the driveshaft end and includes a slinger (231102) for grease retention. The yoke is designed for a 2.024-inch major diameter, 39-spline shaft with a 3.000-inch hub diameter, common on Class 6-7 vocational trucks and industrial drivetrains. You replace it when the splines are worn, the yoke is cracked or wallowed out, or during a driveshaft rebuild to restore proper joint alignment and torque capacity.
