Product Information

Diagram ref no 22

The cotter pin nut fastens the lower ball joint to the front suspension arm and secures it with a locking cotter pin through the castle slots. This prevents the nut from rotating loose, maintaining safe steering and suspension geometry during operation.

Over time, nuts can wear, corrode, or lose torque retention due to repeated assembly, age, or exposure to moisture and road debris. A weakened or reused nut may compromise the ball joint’s security, leading to excessive play or unsafe suspension movement.

When to Replace:
• During front suspension rebuilds or ball joint replacement.
• If the original nut is rusted, damaged, or has distorted threads.
• Whenever the cotter pin is replaced, ensuring proper torque and locking function.

Replacing a new cotter pin nut restores factory-level safety, alignment integrity, and reliability in your classic Porsche’s suspension system.
