Diagram Ref No 14 

The flange provides the mounting connection between the gearbox differential and driveshaft, allowing engine torque to be transferred to the rear wheels.

An aftermarket alternative to the original Porsche component, suitable for drivetrain servicing and specialist gearbox repairs.

What Does It Do?

The driveshaft flange connects the gearbox output to the inner driveshaft joint.

It provides a secure mechanical connection, transferring rotational force from the differential to the rear wheel during acceleration and driving.

Why Is It Important?

A correctly fitted flange helps maintain reliable power delivery and secure driveshaft mounting.

A worn or damaged flange may cause:

• Knocking during acceleration or deceleration
• Excessive drivetrain vibration
• Movement at the driveshaft connection
• Increased wear to adjoining components

These symptoms may also 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 retaining bolts
• Corrosion around mounting surfaces
• Damage during driveshaft removal

When Should It Be Replaced?

Replace the flange if it shows cracking, distortion, damaged splines or excessive mounting point wear.

It should also be inspected during driveshaft replacement, gearbox rebuilding or differential repairs.

Why Choose OE Match?

OE Match offers aftermarket replacement components for Porsche owners and specialist workshops.

This short driveshaft flange provides a practical alternative to the Genuine Porsche component, allowing damaged drivetrain parts to be renewed without replacing the complete gearbox.

Installation Notes

Confirm the correct short flange reference for the vehicle's manual or PDK transmission.

Inspect the gearbox output splines, shaft seals, retaining hardware and driveshaft joint before installation.

Follow Porsche's specified fitting procedures and tightening settings.
