Information
Groove nut for front wishbone ball joint
This groove nut is used to secure the front lower wishbone (A-arm) ball joint on classic Porsche suspension systems. Manufactured to the exact dimensions and thread specifications of the original Porsche part, it provides reliable clamping strength and precise seating of the ball joint within the control arm.
Sold each, fits left and right
Fits:
Porsche 911 1969 - 1989
Porsche 914 1972 - 1976
Diagram ref no 17
This groove nut locks the ball joint securely into the front wishbone, maintaining correct alignment and preventing movement under cornering loads and braking forces. Its machined groove design allows for proper engagement with a locking ring or pin, ensuring long-term stability and safety.
With age, the original groove nut may corrode, lose thread integrity, or deform during removal. Using a worn or non-spec nut can lead to incorrect torque, potential loosening, or suspension play.
Replace when:
• Replacing the front ball joints or wishbone assemblies
• The threads are damaged, corroded, or rounded
• Performing a front suspension rebuild or alignment correction
Installing a fresh groove nut ensures proper torque retention, precise alignment, and dependable suspension performance.
