It connects a 1710 series universal joint to a splined transmission or axle output shaft, securing the joint with straps and bolts. Truck owners typically replace this part when splines wear or the yoke ears become stretched or damaged, which can cause driveline vibration. It is a common repair item during U-joint replacement to ensure a tight, balanced connection.
