Diagram ref no 13

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
•  Connects front wishbone/control arm to wheel carrier
•  Allows steering and suspension articulation
•  Maintains correct front suspension geometry
•  Supports precise steering response and stable handling
•  Helps reduce suspension play and uneven tyre wear

Ball joints are subjected to constant suspension load, steering movement, and road vibration. Over time, internal wear can create excessive play within the joint, leading to vague steering, suspension knocking noises, unstable handling, and uneven tyre wear. Replacing worn ball joints restores safe suspension operation and factory steering precision.

When to replace
  Excessive steering play or vague handling
  Knocking or clunking noises from front suspension
  Uneven front tyre wear
  Failed suspension inspection or MOT
  Visible wear or looseness in suspension joint
  During front suspension rebuild or restoration
