Driveshafts & Parts

The Porsche Driveshaft Bolt M10 × 61 is a genuine OEM fastener engineered to secure the CV joint and driveshaft assembly. Designed to handle the high loads and torque of Porsche drivetrains, this bolt ensures the driveshaft remains properly aligned and firmly attached, preventing unwanted play, vibration, or detachment.

What This Product Does:
- Secures the CV joint / axle / driveshaft / retainer plate to the hub, transmission, or housing — preventing axial movement or loosening.
- Maintains the precise alignment and attachment of the driveshaft/CV assembly to ensure proper torque transfer, seat sealing, and to avoid play or imbalance.
- Helps keep the drivetrain safe and in correct mechanical integrity — without this bolt, the driveshaft or CV joint could shift, loosen or detach under load.
Symptoms Of A Worn, Damaged, Or Missing Bolt:
- Vibration or shuddering from the rear (or affected axle) under acceleration or at speed, due to misalignment or imbalance.
- Unusual noises such as knocking, clunking, or metallic sounds from the driveshaft or hub area, especially under load.
- Axial play or movement in the driveshaft or CV joint when tested — the axle may feel loose or shift in/out.
- Leaking seals or boot damage — misalignment might cause stress on CV boots, axle seals, or hub seals, leading to tears or leaks.
- Loose or missing bolt upon visual inspection (you might notice the head of a missing bolt or damage where the bolt should be).
- Safety & reliability: A secure driveshaft is critical to safe operation — if the bolt fails, the driveshaft/CV could detach or cause mechanical damage.
- Maintains proper alignment & balance: Ensures no unwanted movement or imbalance that can accelerate wear or damage other components.
- Protects other parts: Prevents stress on CV joints, hubs, wheel bearings, seals, etc.
- Avoids cascading damage: A failing or loose bolt can lead to catastrophic failure in drivetrain components, which would be far costlier to repair.

Porsche Driveshafts & Driveshaft Parts | Precision Power Delivery & Smooth Driveline Operation
Driveshafts play a vital role in transmitting engine power from your Porsche’s gearbox or differential to the wheels. A well-balanced driveshaft ensures smooth, vibration-free performance, allowing torque to be delivered evenly across all driving conditions.
At Design911, we supply premium driveshafts and replacement driveshaft components engineered to meet or exceed original performance specifications. Each unit is manufactured from high-strength steel or lightweight alloy for maximum torsional rigidity and balance. Our range also includes complete driveshaft assemblies, universal joints, CV joints, couplings, and hardware — all designed for long-lasting reliability and precise fitment.
Whether you’re restoring a classic 911, maintaining a Cayman or Boxster, or upgrading a performance model, our driveshafts and parts ensure smooth power transfer, reduced vibration, and dependable performance.
What Do Driveshafts Do?
The driveshaft is a critical link in your Porsche’s powertrain, connecting the transmission to the driven wheels. It rotates at high speeds, transmitting torque and maintaining balanced motion across suspension travel and gear changes.
Core Functions:
- Transfers engine torque from gearbox or differential to the wheels.
- Maintains rotational balance for smooth driving and handling.
- Absorbs movement between suspension and transmission components.
- Supports consistent traction and performance under load.
Without a properly functioning driveshaft, power delivery becomes uneven, causing vibration, noise, and potential drivetrain failure.
Why Do Driveshafts Fail or Wear Out?
Driveshafts and their components endure constant rotational forces, torque, and flexing during operation. Over time, these stresses — along with environmental exposure — lead to wear and imbalance.
Common Causes of Failure Include:
- Worn CV or universal joints causing vibration or clunking noises.
- Damaged or torn driveshaft boots allowing grease loss and contamination.
- Corrosion or impact damage to the shaft itself.
- Imbalance from worn bearings or misalignment.
- Excessive torque loads from high-performance driving.
When these components wear out, symptoms such as vibration, knocking, or shuddering during acceleration or braking may occur — indicating it’s time for inspection or replacement.
Why Replace Your Porsche Driveshafts & Parts?
Replacing a worn or damaged driveshaft or its components restores balance, smoothness, and reliable torque transfer. Upgraded driveshafts or reinforced components can handle higher power output and reduce rotational mass for enhanced performance.
Key Benefits:
- Restores smooth, vibration-free driveline operation.
- Prevents transmission and differential wear.
- Improves torque transfer and handling precision.
- Reduces noise, vibration, and harshness (NVH).
- Manufactured from high-strength materials for durability.
- Available as complete driveshaft assemblies or individual parts.
It’s recommended to inspect and replace driveshaft joints, couplings, and boots during clutch or transmission servicing to prevent secondary damage.
