This part is used in the all-wheel-drive drivetrain system on selected Porsche 996 and 997 models.

What This Part Does / Functions
•  Transfers torque through the AWD drivetrain
•  Connects drivetrain components between transmission / transfer output and front axle final drive
•  Supports front axle drive operation on Carrera 4, Carrera 4S and Turbo models
•  Helps maintain smooth and balanced driveline rotation
•  Replaces a worn, noisy, vibrating or failed original cardan shaft
•  Helps reduce drivetrain vibration, knocking or shudder
•  Provides correct Genuine Porsche length, balance and joint specification
•  Supports factory Porsche AWD performance and driveline refinement.

Why Replace This Part?
The cardan shaft is a high-speed rotating drivetrain component. It is exposed to torque load, vibration, road conditions, heat and continuous movement. Over time, joints, boots, flanges or balance characteristics can wear or become damaged. A worn or incorrect shaft can cause vibration, knocking, rumbling or shudder under acceleration.

Replacing it with a Genuine Porsche cardan shaft helps restore correct AWD driveline operation, smooth torque transfer and OE Porsche drivetrain quality.

Common Symptoms of a Faulty Cardan Shaft
•  Driveline vibration under acceleration
•  Vibration at certain road speeds
•  Knocking or clunking from underneath the vehicle
•  Shudder during take-up of drive
•  Rumbling or bearing noise from the driveline area
•  Excess play in shaft joints or flanges
•  Split or damaged cardan shaft boot
•  Damage after underside impact
•  Fault confirmed during drivetrain inspection.

When to Replace This Part
•   If vibration or knocking is traced to the cardan shaft
•   If the shaft is damaged, bent or out of balance
•   If joints, boots or flanges have excessive wear
•   During AWD drivetrain repair or overhaul
•   After underside impact or accident damage
•   If the original shaft has failed inspection
•   When replacing related front axle final drive, transmission or driveline components.

Where It Fits on the Car
This cardan shaft fits in the AWD drivetrain / front axle final drive system. It connects the drivetrain output to the front axle final drive, allowing the vehicle’s all-wheel-drive system to transfer torque to the front axle.

Correct installation, alignment and torque settings are essential to prevent vibration and ensure smooth drivetrain operation.
