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.

Product Information
Product Information
Track rod inner joint.
This OE-Match steering set includes two inner track rod joints (2× 99734732201), providing a complete left-and-right replacement for the steering linkage on Porsche 987 Boxster, 987C Cayman, and 997 911 models.
SET OF 2, left & right tie rod joints.

Fits :
Porsche 987.1 Boxster 2005 - 2008
Porsche 987.2 Boxster 2009 - 2012
Porsche 987C.1 Cayman 2006 - 2008

Porsche 997.2 2009 - 2012

Diagram Ref No 6.

These inner joints connect the steering rack to the outer tie rods, transmitting steering input directly to the front wheels.

Each joint is manufactured to OE specifications with hardened steel housings, precision ball-and-socket articulation, and corrosion-resistant construction for long-term reliability.

Replacing both sides as a matched pair ensures consistent steering feel, improved alignment stability, and balanced handling - particularly important on higher-mileage vehicles or cars used for spirited driving.

Worn inner joints develop play over time, causing vague steering, instability, uneven tyre wear, and reduced driver confidence. Replacing both ensures tight, precise and predictable steering performance, returning your Porsche to factory-sharp response.

When to replace:
 Steering feels loose or imprecise
 Knocking or clunking noises over bumps
 Uneven or accelerated front tyre wear
 Alignment constantly drifts or cannot be set correctly
 Visible play during steering inspection
 Recommended during steering rack, tie-rod or front suspension overhaul

Set of 2 x adjustable track rod ends

Correct geometry for lowered cars with bump steer adjustment and angled head.

Bump steer adjustable – The built in bump steer adjustment lets you dial in a minimal bump steer curve.

Angled head – Lower the car and the tie rods angle down. This shifts the ball stud from its center and limits the available range of articulation.
We solve this problem by angling the head to move the stud back towards the center of its range of articulation at static ride height.

Fully weather sealed – Proper boot at the ball stud to keep water and contaminant out for extended life.

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.

Steering rack mounting hardware plays a critical role in maintaining steering precision and chassis stability. Correct fastening ensures the steering rack remains securely mounted under load, helping maintain accurate steering response and reducing unwanted movement or vibration. Over time, original hardware can corrode, stretch, or become damaged during servicing, making replacement essential during steering or suspension repairs.

Produced as an OE Match replacement, this pan head screw is designed to replicate the original Porsche hardware specification for dependable fit and performance. It is ideal for maintenance work, steering rack replacement, restoration projects, or replacing worn or missing original fasteners.

Why power steering rack hardware replacement matters
Power steering rack mounting screws are subjected to constant vibration, steering loads, and suspension movement. Over time, hardware can corrode, stretch, or lose clamping strength, which may lead to unwanted steering movement, vibration, or reduced steering precision. Replacing worn or damaged fasteners helps maintain secure steering rack mounting and reliable handling performance.

When power steering rack screws should be replaced
•  During steering rack replacement or removal
•  If original hardware is corroded or damaged
•  When threads show signs of wear or stretching
•  If steering vibration or movement is detected
•  During suspension or front subframe servicing
•  As part of restoration or preventative maintenance work

Why Power Steering Rack Hardware Replacement Matters
Power steering rack mounting screws are exposed to constant vibration, steering loads, and suspension movement.

About Steering Parts

Porsche Steering Parts

At Design911, we stock a wide range of Porsche steering parts for both classic and modern models. While turning the wheel may feel simple, the mechanical system behind it is complex and crucial for your safety, handling, and driving enjoyment. From everyday road cars to high-performance Porsche track builds, we supply everything you need to keep your steering precise and reliable.

Our product range includes:

  • Steering Racks & Rack Mounts

All parts are carefully sourced to ensure OEM quality and fitment, with both replacement and upgrade options available.

Common Porsche Steering Issues

Even the best-engineered Porsche components experience wear over time. Common steering problems include:

  • Low Power Steering Fluid- A frequent cause of heavy or unresponsive steering. Topping up fluid restores smoothness, but continual loss may indicate a leak.
  • Power Steering Leaks - If topping up fluid doesn’t solve the issue, check for leaks. Power steering fluid is usually clear or pink — look for patches under your car when parked.
  • Failing Steering Rack Mounts - Modern Porsches use rack-and-pinion systems. When rack bushings wear out, symptoms include - Jerky steering when going over bumps, Inconsistent wheel feel and Clunking, clicking, or popping noises in the column

If you notice any of these issues, it’s important to get your Porsche inspected by a specialist to prevent further damage.

Diagnosing & Replacing Porsche Steering Components

Steering issues are not always easy to diagnose without specialist knowledge. Our advice: book in with a Porsche specialist garage for a full inspection. They can pinpoint whether the issue is with the rack, joints, bushings, or hydraulics.

If replacement is required, our website makes it simple. Select your Porsche model and year, and we’ll filter the catalogue to show only compatible steering spares for your car.
