Autopart International 1701-71170 Driveshaft Flex Joint

The Autopart International 1701-71170 is a driveshaft flex joint, also known as a flex disc, giubo, or hardy disc. This flexible reinforced rubber component is a critical part of the driveline system in rear-wheel drive and all-wheel drive vehicles.

Key Features:

• Reinforced rubber construction with metal-sleeved bolt holes for durability
• Transmits torque from the transmission or transfer case to the driveshaft while allowing slight angular movement
• Dampens drivetrain vibrations and reduces stress on driveline components
• Compensates for slight misalignment between driveshaft and transmission or differential
• Direct replacement for worn or damaged original equipment

Function and Benefits:

The flex joint serves a similar purpose to universal joints by transferring rotational force while allowing movement between connected components. It reduces vibration transmission from the engine and transmission to the driveshaft, providing smoother operation and extending the life of driveline components. Over time, the rubber material can dry out, crack, or tear from exposure to heat and road conditions, leading to drivetrain vibrations or clunking noises that indicate replacement is needed.

This replacement flex joint restores smooth driveline operation and eliminates vibrations caused by worn components. Installation requires removal of fasteners connecting the joint to both the driveshaft and transmission or differential flanges.
