• Function: Secures suspension and chassis components under load
• Position: Used across control arms, subframes, and steering joints
• Symptoms of wear: Loose suspension joints, vibration, uneven torque
• Benefits: Factory-spec strength, self-locking reliability, vibration resistance
• Installation: Replace after removal; torque to Porsche specification

Whether used on control arms, subframes, or steering links, this original fastener restores the vehicle’s factory integrity — ensuring the performance and handling precision Porsche is known for.

Self-locking nuts are designed for single-use applications — once removed, their locking feature weakens, risking torque loss or loosening under vibration. Over time, exposure to heat, road debris, or corrosion can also degrade the nut’s surface coating and internal locking mechanism.

Replace this nut when:
•  Performing control arm or suspension link service
•  Reinstalling subframe, engine mount, or steering components
•  The nut shows signs of corrosion, deformation, or thread wear
•   A torque-to-yield fastener procedure is required (one-time use)

Using a fresh Genuine Porsche PAF102861 nut ensures safe, consistent torque and preserves the alignment and handling precision of your Porsche.
