Track Rod Inner Joint. Porsche 964 C4 / RS

Track Rod Inner Joint.
Upgrade or refresh the front steering linkage of your Porsche 964 with this inner track rod joint. Designed for the Carrera 4 and RS models from 1989 to 1994, this precision joint sits at the inner end of the tie rod, ensuring precise steering geometry and eliminating play. Whether you’re restoring a 964 or improving the performance of a track-prepared example, this component restores sharp, dependable steering feel and correct front-end alignment.

What This Product Does:

• The track rod system connects your steering rack to the wheels, transmitting input from the steering wheel to the front wheels. The inner joint is a key pivot point that allows the rod to articulate as the suspension moves, while keeping the steering geometry true.
  
• A healthy inner joint ensures the rod length and alignment remain correct, minimal play is present, and the front wheels respond precisely to input without unwanted movement or lash.
• In performance or modified cars, maintaining tight inner joints is especially important for steering precision, alignment retention, and overall front-end stability.

Symptoms Of Wear Or Failure:

• Steering play or slop — a vague or loose feeling in the steering, particularly around straight-ahead or under small inputs.
  
• Knocking or clicking noise from the front end, especially when going over bumps or during steering movements, indicating the joint is moving where it shouldn’t.
  
• Front alignment drifting or uneven tyre wear — because the rod end is no longer maintaining correct alignment under load.
  
• Delayed or imprecise steering response — the front wheels might not change direction as promptly because the linkage has movement built in.
  
• Inspection shows visible wear or looseness — The joint may have excessive play when physically moved, or the boot might be torn or missing, exposing the internals to dirt or contamination.
  
  

Why Replacement / Upgrade Matters:

• A worn or loose inner track rod joint undermines your front-end suspension geometry and steering accuracy. Replacing with a new correct part ensures the steering system functions as intended, renewing precision and responsiveness.
• On a Porsche 964 (especially C4 or RS models) where handling and driver feedback are key, a tight inner joint helps maintain the connection between driver input and front-wheel behaviour — critical for both everyday driving and spirited use.
• It also reduces the risk of secondary wear: when one joint in the system is loose, other components (tie rods, rack ends, knuckles) may suffer increased stress or wear.
• From a safety and inspection viewpoint, worn rod ends are common failure items during vehicle exams — replacing the inner joint is part of good maintenance.
• If modifications (wider tyres, stiffer suspension, track use) are in place, ensuring all steering joints are in top order preserves the benefit of those upgrades and avoids a “weak link” in the steering chain.
