The driveshaft bolt secures the driveshaft (CV joint) to the drivetrain assembly, maintaining the correct clamping force to minimise movement and ensure reliable transmission of engine torque to the wheels.
Key Features & Benefits
• Premium ROHLER titanium construction
• Direct replacement for Porsche 90006721102
• Lightweight with an excellent strength-to-weight ratio
• Outstanding corrosion resistance
• Precision-machined for OEM-style fitment
• Suitable for road, fast road, and motorsport applications
• Sold individually (purchase the required quantity for your vehicle)
Why Replacing Driveshaft Bolts Matters
Driveshaft bolts are subjected to high torque loads and constant vibration. During driveshaft or CV joint servicing, Porsche recommends inspecting the mounting hardware, and replacing worn or damaged bolts helps maintain the correct clamping force and reduces the risk of loosening during operation. High-quality replacement bolts are particularly important on performance and high-mileage vehicles.
When to Replace Driveshaft Bolts
• During CV joint or driveshaft replacement
• When replacing CV boots
• If the original bolts are corroded, damaged, or have worn threads
• If bolt heads are rounded or show signs of stretching
• During drivetrain restoration or performance upgrades
• Whenever the original fastening hardware no longer meets specification

Information
Replacement Driveshaft. REAR.
Genuine Porsche original equipment (OE) drive shaft assembly, also referred to as a constant-velocity (CV) axle, that transfers power from the transmission to the rear wheels in manual-equipped Porsche 911 (996) Carrera 4S models.
Sold each. Fits left and right side.
Fits:
Porsche 996 C4S 2002–2005 with Manual transmission
This product supersedes Porsche's old part numbers: 99633202406, 99633202417, 99633202424.
The rear CV axle assembly is a key drivetrain component that transmits torque from the gearbox output to the rear differential and wheels. It incorporates constant velocity joints (CV joints) and a balanced shaft designed to handle rotational forces and suspension movement while maintaining smooth and reliable power delivery to the driven wheels.
Function:
• Torque Transfer: Moves engine power from the transmission output to the rear differential and wheels.
• Articulation: CV joints allow flexibility for suspension movement while maintaining constant rotational velocity.
• Balance & Durability: Precisely balanced to minimise vibration and engineered for long-term service life under load conditions typical of performance driving.
A worn or damaged CV axle can lead to symptoms such as:
• Clicking or popping noises during cornering
• Vibration or shimmy under acceleration
• Grease leakage from boot failure
• Unstable or uneven power delivery.
Using a Genuine Porsche axle assembly ensures you retain factory-specified torque capacity, balance, and joint geometry, preserving drivetrain smoothness and reliability - especially under spirited driving conditions.
When to replace - Replace this rear CV axle assembly if you observe:
• Persistent vibration or noise from the rear drivetrain
• Visible CV boot damage or leaking grease
• Worn CV joints or shaft imbalance
• After accident damage to the suspension or axle area
• During major clutch or transmission servicing as preventative maintenance
