U-JOINT (CAT CT300970)

CT300970: A worn U-joint can cause driveline vibration and eventual power loss. The U-joint, or universal joint, is a mechanical coupling that transmits rotary motion between shafts that are not perfectly aligned. A failing U-joint often produces a clicking or clunking noise during direction changes. This aftermarket replacement part references CAT as the OE maker and cross-references part number CT300970. The U-joint's plain mechanical function is to accommodate angular misalignment between connected shafts. A concrete generic failure consequence is that a seized U-joint can lead to complete driveline failure. Verify the serial number or application, then call (562) 693-7748.
