It features a wing-bearing (wing-DWT) design where the bearing caps bolt to the driveshaft yoke, providing a secure, serviceable connection. This greasable U-joint is built for Rockwell 58WB-1 series applications. It is replaced when it becomes worn, develops excessive play, or fails—typical symptoms being driveline vibration, clunking, or loss of power transmission.
