Driveshaft Bolt M10 X 61. Porsche 996 Carrera / 997.1 Carrera 1998-08

Driveshaft Bolt M10 X 61.
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).
  
  

Why Replacement Matters:

• 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.
