Track rod inner joint. Porsche 987 Boxster / 987C Cayman / 997

Track rod inner joint. Street version.
The steering rack controls the front wheels by means of two track rods, terminated by replaceable joints - the "Track Rod Ends", attached to the swivel hubs. These will eventually wear, leading to problems with steering and handling, as well as being a failure point on the UK MOT and presumably on the statutory inspections in other countries.
Sold each, 2 required per vehicle - one on each side.

Diagram Ref No 6.

•  Position: Front axle — inner connection between steering rack and track rod / tie rod end

• Function: Transfers steering rack movement into lateral wheel motion;  Maintains front-end steering geometry and alignment;  Absorbs steering loads while allowing articulation through the joint.

Because the inner joint experiences constant load, steering motion and exposure to road conditions, its wear can lead to looseness or excessive play. A worn or failing joint can cause sloppy steering, uneven tyre wear, loss of alignment, wandering or imprecise handling - which not only affects driving confidence but also safety. Replacing the joint restores sharp, reliable steering and preserves proper alignment under load.

When to replace:
• Noticeable play or looseness when steering at stand-still or during turning
• Clunking, knocking, or unusual noise coming from the front suspension/steering when going over bumps or during steering movement
• Difficulty maintaining correct front-end alignment, or frequent need to re-align after small adjustments
• Uneven or premature front tyre wear
• After wheel-hub, steering rack or tie-rod replacement or maintenance - as a precaution or when parts are disturbed
• As part of scheduled maintenance on higher-mileage Porsche 987 / 997 vehicles
