Diagram Ref No 11 

Fitted to the transmission output, the flange connects the gearbox differential to the driveshaft, transferring engine power to the driven wheels.

Designed to replace a worn or damaged original component during gearbox servicing or drivetrain repairs.

What Does It Do?

The driveshaft flange connects the gearbox differential output to the driveshaft.

It transfers rotational power from the transmission to the wheel while maintaining the correct mounting position of the driveshaft assembly.

Why Is It Important?

A secure driveshaft connection is essential for smooth power delivery.

A damaged flange may cause:

• Knocking during acceleration or deceleration
• Excessive drivetrain vibration
• Movement around the driveshaft connection
• Wear to adjoining transmission components

Similar symptoms can result from worn CV joints or gearbox mountings.

Why Do Driveshaft Flanges Fail?

Common causes include:

• Worn or damaged internal splines
• Repeated high-torque loading
• Loose or damaged mounting hardware
• Corrosion around mating surfaces
• Damage during gearbox or driveshaft removal

When Should It Be Replaced?

Replace the flange if it is cracked, distorted or shows excessive spline or mounting surface wear.

It should also be inspected during gearbox rebuilding, driveshaft replacement or investigation of drivetrain vibration.

Installation Notes

Confirm that the gearbox requires the long flange before installation.

Inspect the output shaft seals, retaining rings and driveshaft connection. Use the specified Porsche fitting procedures and tightening settings.
