Installed at the outer end of the front lower wishbone/control arm, the ball joint forms a critical pivot point between the suspension arm and wheel hub carrier. It allows controlled articulation during steering and suspension travel while maintaining correct wheel alignment and suspension movement. Proper ball joint operation is essential for steering accuracy, chassis stability, and predictable handling.

This early-style ball joint features the correct configuration for early Porsche suspension systems and is suitable for restoration work, suspension refurbishment, or replacement of worn original components. Certain versions are supplied with lock plate and split pin hardware depending on application.

The front wishbone ball joint connects the lower control arm to the wheel carrier while allowing controlled steering and suspension movement. It supports stable handling, precise steering response, and proper front wheel alignment.

Function
