Diagram Ref No 2
Constructed from high-strength forged steel and fitted with a precision-engineered ball joint, the track rod is designed to withstand continuous steering forces, road impacts and suspension movement. The sealed joint is protected against dirt and moisture, ensuring long-lasting performance and maintaining the sharp steering response and handling characteristics expected from a genuine Porsche component.
What This Product Does:
- Connects the steering rack to the front wheel hub assembly.
- Transfers steering input accurately to the front wheels.
- Allows suspension movement while maintaining steering control.
- Maintains correct front wheel alignment.
- Provides smooth and precise steering response.
- Supports vehicle stability during braking and cornering.
- Reduces unwanted steering play and vibration.
- Forms a critical part of the front steering system.
Symptoms Of Wear Or Failure:
- Steering wheel play or looseness.
- Knocking or clunking noises from the front suspension.
- Uneven or accelerated tyre wear.
- Vehicle pulling to one side.
- Vibration through the steering wheel.
- Poor steering response or reduced precision.
- Difficulty maintaining wheel alignment.
- Excessive movement in the ball joint during inspection.
- Split or damaged protective dust boot.
- MOT or vehicle inspection failure due to steering joint wear.
Why Replacement Matters:
- The front outer track rod is subjected to constant steering movement, road shocks, cornering loads and exposure to water, dirt and road salt. Over time, the internal ball joint and protective boot can wear, allowing contamination to enter and increasing joint play.
- A worn track rod can reduce steering accuracy, affect wheel alignment and accelerate tyre wear. Continued operation with excessive play may place additional strain on the steering rack and suspension components, while also compromising vehicle handling and safety.
- Replacing a worn front outer track rod restores precise steering response, correct suspension geometry and predictable vehicle handling. A genuine Porsche replacement guarantees factory-correct fitment, premium-quality materials and long-term durability, helping maintain the outstanding steering precision, safety and driving performance your Porsche was engineered to deliver.

This lock nut fits in the steering and chassis assembly, commonly used at the steering rack tie rod end / track rod end connection. Depending on model and application, M12 x 1.5 lock nuts may also appear in suspension and control arm fastening locations.
This is a small but important OE Porsche hardware item that helps secure critical chassis and steering components to the correct factory standard.
Functions
• Secures the steering rack tie rod end connection
• Provides a factory-correct M12 x 1.5 locking fastening point
• Helps maintain secure attachment of steering and chassis components
• Supports correct steering geometry and component stability
• Helps prevent loosening caused by vibration, road loads and suspension movement
• Suitable for replacement during steering rack, track rod or tie rod end work
• Maintains OE Porsche fitment and fastening quality.
Lock nuts are designed to provide secure fastening and are often recommended for replacement after removal, especially on steering and suspension components. Over time, the nut can corrode, seize, round off or lose its locking effectiveness. Replacing the original nut with a Genuine Porsche OE M12 x 1.5 lock nut helps ensure the tie rod end or related component is secured correctly and safely. This is especially important on steering components, where correct fastening is essential for accurate steering response and road safety.
When to replace
• When replacing a steering rack tie rod end or track rod end
• When removing or refitting steering rack components
• If the original nut is corroded, seized or damaged
• If the nut thread is worn or the locking function is compromised
• During suspension or steering overhaul work
• After accident repair or chassis component replacement
• When restoring the car with correct OE Porsche hardware.
