When Should It Be Replaced?

Replacement is recommended when the flange shows visible damage or excessive wear.

Check for:

• Damaged or worn splines
• Cracked or distorted mounting surfaces
• Worn driveshaft bolt holes
• Excessive play at the driveshaft connection

The flange should also be inspected during gearbox repairs or CV joint replacement.

What Does It Do?

The driveshaft flange forms the mechanical link between the gearbox differential and the rear driveshaft.

It transfers rotational force to the driven wheel while keeping the driveshaft securely attached to the transmission.

Why Do Driveshaft Flanges Fail?

Common causes include:

• Repeated high-torque loading
• Wear around splined connections
• Loose or damaged retaining bolts
• Corrosion of mounting surfaces
• Damage during driveshaft removal

A defective flange may contribute to drivetrain knocking, vibration or excessive movement.

Why Choose OE Match?

OE Match provides replacement components for Porsche owners and workshops seeking an aftermarket alternative to original Porsche parts.

This long driveshaft flange allows damaged transmission hardware to be renewed while retaining the intended mounting arrangement.

Installation Notes

Inspect the differential output, retaining components, oil seals and driveshaft joint before fitting.

Ensure the correct long flange is selected and follow Porsche's specified installation and tightening procedures.

Why Is It Important?

A secure flange connection is essential for reliable power transfer, particularly in high-performance GT3 applications.

Worn mounting points or damaged splines can place additional strain on the driveshaft and surrounding transmission components.

Manual Gearbox Driveshaft Flanges
