It features a 1.188-inch bearing cap diameter, a 3.625-inch span across the caps, and external snap rings for retention. The grease fitting is located on the side of the cross, allowing routine lubrication to extend service life. This U-joint is typically replaced when wear causes driveline vibration, clunking, or looseness, and it fits a wide range of heavy-duty trucks, commercial vehicles, and 4WD pickups that use the Spicer 1350 series driveline components.
