Febi Rear Tailshaft Coupling 101774

A tailshaft joint, also known as a universal joint or U-joint, is an essential component of a vehicle's drivetrain system. It is a flexible joint that connects the transmission or transfer case to the driveshaft, which then links the drivetrain to the rear differential. The primary purpose of the tailshaft joint is to transfer torque from the engine to the rear wheels, allowing the vehicle to move forward. It is designed to compensate for the angular change between the transmission and the driveshaft caused by uneven road surfaces, suspension movement, and drivetrain vibration. The tailshaft joint also allows for a smooth transfer of power, eliminating driveline vibrations, and reducing drivetrain wear and tear.

The tailshaft joint contains two 'U'-shaped arms, which are connected by a cross or spider-shaped device. The joint is sealed with grease to reduce friction, and the cross is held in place by bearing cups. As the vehicle moves, the tailshaft joint flexes and twists, allowing the driveshaft to maintain a consistent speed and angle. Without the tailshaft joint, rigid driveshafts would be required, resulting in a harsh ride and decreased vehicle performance. It is important to regularly inspect and maintain the tailshaft joint to prevent failure, extend its lifespan, and ensure the safe operation of the vehicle.
