• The track-rod assembly transmits steering input from the steering rack/column to the wheels. The inner joint is a critical pivot point enabling the rod to align with changing suspension and steering geometry.
• This inner joint ensures that the steering rack’s motion is translated precisely to the front wheels, without unwanted play or slack in the linkage.
• Because the joint allows articulation yet must resist lateral movement and play, it contributes to steering precision, directness of input, and accurate response of the front wheels.
• A properly functioning inner joint means the front wheels respond accurately to the driver’s steering input and hold correct alignment/tie-rod geometry under load (braking, cornering).

• Steering play or vague steering feel — the front end lacks sharpness, there may be a slight dead-zone or loose feeling at the steering wheel.
  
• Clunking, knocking or clicking noises from the front end when going over bumps or when turning the steering wheel, indicating excessive movement in the joint.
  
• Uneven or rapid tyre wear on the front wheels — because the tie-rod geometry is compromised, alignment may drift under load.
  
• Delayed or imprecise steering response — the car may feel less direct or “mushy” when steering.
  
• On inspection: visible play in the joint, torn rubber boots, corrosion or visible wear in the fork end.

Why Replacement / Upgrade Matters:

• A worn inner joint undermines the entire steering chain: even if other components (outer rod ends, rack) are new, a weak inner joint will allow slack, reduce precision and degrade response.
• On a Porsche 964, which is performance-oriented and often driven spiritedly, steering feel and precision are key. Replacing this joint ensures the driver retains direct feedback and control.
• Replacement improves safety and long-term reliability: worn joints can lead to much worse outcomes (mis-steering, alignment issues).
• It also maintains value: correctly replacing steering components is important for older collect- and performance cars — a well-maintained steering linkage is viewed positively.
• If the vehicle has been modified (wider tyres, lower suspension, track use), ensuring this inner joint is in good order is essential to getting maximum benefit from those upgrades.
