Information
Wishbone ball joint front - cotter pin
Ball joint lock pin is an suspension fastener designed to secure the front lower ball joint to the strut or wishbone assembly on classic Porsche models. It installs into the ball joint mount to secure the connection between suspension links and steering knuckles. It’s suitable for maintenance, rebuilds, or restoration of front suspension components and fits directly without modification.
Sold each, Fits left and right.
Fits:
Porsche 911 1969 - 1989
Porsche 914 1972 - 1976
Diagram ref no 20
The lock pin provides a secure fastening point that holds the front lower ball joint in place, ensuring the suspension components remain correctly aligned under load and motion. It helps transmit steering forces while keeping the joint assembly stable during driving.
Installed through the ball joint and suspension link interface, this pin maintains clamping and positional integrity, aiding the suspension’s ability to articulate smoothly while resisting unwanted movement. It works in conjunction with the control arm and steering knuckle to support safe, responsive handling.
Front suspension hardware like the ball joint lock pin can wear, corrode, or lose clamping strength over time, which may lead to play in the suspension, uneven tyre wear, and compromised steering feel. Replacing worn or damaged pins with OE Match parts helps maintain precise suspension geometry and consistent handling characteristics.
When to replace:
• Ball joint pin is corroded, bent, or worn
• Loose or sloppy front suspension feel
• During ball joint, control arm, or strut service
• Restoration of classic suspension systems
• After removal or disassembly of front suspension
