Universal Flex Disc

Located between the transmission and driveshaft, the giubo (also guibo) joint is a flexible rubber drive coupling that joins driveline components to reduce vibration, while allowing a limited range of flexibility. Joint rubber deteriorates over time from torque stress and heat hardening. A failed joint is a common cause of driveline noise and vibration. This joint should be inspected during normal maintenance for signs of heat cracking and tears in the rubber. Failed joints should be replaced before they cause additional damage and expense or disable the vehicle.
