Reconditioned Steering rack, for RHD (Right Hand Drive) vehicles.
The steering rack’s primary role is to convert the driver’s steering wheel movement into precise lateral motion that turns the front wheels. It operates through a rack-and-pinion mechanism, where a small toothed gear (the pinion) engages a toothed bar (the rack). As the steering wheel turns, the pinion rotates, moving the rack left or right - steering the front wheels accordingly.

• Position on Vehicle: Front steering rack assembly mounted under the front body structure, linking the steering column to the front tie-rods and controlling lateral wheel movement.

• Cross-Reference / Alternative Numbers: OEM Porsche part number: 997 347 012 09 (also shown as 99734701209), Supersedes earlier reference numbers 99734701204 / 99734701205 / 99734701206 / 99734701207 / 99734701208

• Applications: Replacement when the original steering rack shows signs of wear, leakages, play, inconsistent assist or compromised steering feel - maintaining the authentic Porsche driving experience.

The steering gear is fundamental to accurate, safe and confident vehicle control. A worn, leaking or loose rack can introduce play, reduce steering precision, cause drift or uneven tyre wear, and compromise your vehicle’s handling integrity. Replacing it with the genuine Porsche part ensures factory-calibre performance, correct geometry, and preserves your car’s handling heritage.

• Observed steering fluid leak or torn boots at the rack end.
• Noticeable play or looseness in the steering wheel or vague centre feel.
• Heavy or inconsistent steering assistance, especially at low speeds.
• Noise or harshness when steering through bumps or turns.
• During major front-end or steering system service when access simplifies replacement.
• High-mileage vehicle where the original rack has done significant duty and may be near its service life.

PLEASE NOTE:

• The surcharge for this reconditioned part will be refunded when the exchange unit is received and approved by us and the relevant manufacturer.
• Please note, surcharge refunds often take an average of 6 to 8 weeks to be approved by the manufacturer.
• Acceptance of the exchange part is at the manufacturer's discretion, based on the part being fit for reconditioning.
• All surcharges and exchanges are subject to our terms and conditions.

Steering rack boot clamping ring.
The Genuine Porsche 99951269309 is a clamping ring / boot clamp used in the steering rack assembly. This integral ring ensures the secure sealing and retention of the steering rack bellows (boots), protecting the inner tie-rod joints and rack mechanism from moisture, dirt, dust and road debris.
Sold each, 2 required per vehicle.

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

Diagram ref no 5

• Position on Vehicle: Installed on the steering rack assembly; it clamps the rack-and-pinion boot (bellows) to the housing or tie-rod to maintain environmental sealing.

•  Applications: Ideal for replacing a degraded or missing clamp when the steering rack bellows have been replaced or when boot integrity has been compromised; essential for maintaining the sealed environment for the rack internals.

Though small, the clamping ring plays a crucial role in protecting your Porsche’s steering rack from contamination and wear. A loose, missing or corroded clamp allows dirt, water or debris to enter the bellows, which can accelerate wear and damage to the rack and tie-rod joints - leading to steering play or failure. Replacing it with the genuine Porsche part ensures proper sealing, longer rack life and consistent steering feel.

When to replace:
•  If the steering rack boot (bellows) is loosened, missing or has previously been replaced but the clamp was discarded.
•  When the clamp is visibly corroded, cracked or no longer secures the boot firmly.
•  During steering rack service, boot replacement or tie-rod replacement when the clamp is accessible.
•  On high-mileage vehicles where original clamps may have deteriorated or were previously reused.
•  To prevent potential steering rack contamination and maintain long-term system reliability.

Even though it’s a small part, the seal ring plays a vital role in your Porsche’s hydraulic steering system. When it fails, you may experience fluid leaks, loss of hydraulic assist, play in the steering or reduced feedback - all affecting handling, safety and longevity of steering components. Replacing the seal ring with the genuine part restores correct sealing, hydraulic pressure retention and the precise steering feel your Porsche expects.

When and why to replace:
• Evident steering fluid seepage around the rack housing or boots, indicating internal seal failure.
• Loss of power-steering assist or degraded steering feel, especially at low speeds or when cold.
• During steering rack replacement or rebuild – when bearing access is available and you want to prevent future leaks.
• As part of front-end or steering system overhaul on high-mileage vehicles where original seals may have aged or hardened.
• Whenever the steering rack hydraulic system is opened or dismantled – fitting a new genuine seal ring ensures proper long-term service.

We strongly recommend replacing the power steering pump at the same time as the steering rack. Swarf (metal particles) in the power steering system can circulate and cause damage to both components. If you choose to replace only the steering rack and, upon return of your exchange unit, we discover that the rack bar is scored or contaminated with swarf, this indicates that debris is present in the system. In such cases, we advise replacing the pump as well.
Please note: if we have advised that there is swarf in the system and you choose not to replace both components, any future warranty claims related to this issue will not be valid. 

Please note good reconditioned steering racks are becoming very hard for us to supply and this is simply because the core exchange units are not being returned to us. If you fail to return the core unit to us within 30 days we reserve the right to charge you the full price of a replacement steering rack.

The most common power steering faults are:
- Leaking power steering
- Torn Gators
- Hard to steering when idling
- Hard to steering one-way
- Steering-Wheel not self-centering
- Noise when Idling
- Noise when steering
- Judders when steering
- Loss of all power in steering
- Semi-Loss of power in steering
- Electric steering problems

Above are just some of the problems our customers are faced with on a day-to-day basis with their power steering units. We can replace your old unit with a Reconditioned unit. If we don't have a replacement available, we can take in your own unit and recondition it for you. Where a new unit can cost £100's we can recondition/supply reconditioned units at a fraction of this price!

All reconditioned racks come with 1 Year or 12,000 miles warranty!!

PLEASE NOTE:

• The surcharge for this reconditioned part will be refunded when the exchange unit is received and approved by us and the relevant manufacturer.
• Please note, surcharge refunds often take an average of 1 to 2 weeks to be approved by the manufacturer.
• Acceptance of the exchange part is at the manufacturer's discretion, based on the part being fit for reconditioning.

For Left Hand Drive (LHD)

On performance-focused sports cars such as the 997 Carrera, Boxster 987 and Cayman 987, the steering rack plays a vital role in road feedback, cornering stability and driver confidence—especially at higher speeds and during spirited driving.

What Does a Power Steering Rack Do?

The steering rack transfers movement from the steering column to the front wheels while hydraulic assistance helps reduce effort at the wheel.
This ensures:

• Smooth and accurate steering response
• Consistent feedback through corners
• Reduced driver fatigue during low-speed manoeuvres
• Predictable handling under load

A worn or failing rack compromises steering precision, safety and overall driving enjoyment.

Why Do Steering Racks Fail?

Over time, steering racks are exposed to high pressure, heat, road debris and vibration, leading to gradual wear. Common failure causes include:

• Internal seal degradation causing hydraulic fluid leaks
• Wear in the rack shaft and pinion gear
• Corrosion from moisture ingress
• Damage caused by contaminated power steering fluid

Typical symptoms of failure include:

• Heavy or inconsistent steering feel
• Power steering fluid leaks
• Knocking or play in the steering
• Steering pull or poor return to centre

Why Replace the Steering Rack?

Replacing a worn steering rack restores:

• Precise steering control
• Correct hydraulic assistance
• Safe and predictable handling
• Confidence at speed and during cornering

Ignoring steering rack issues can accelerate wear on related components such as track rods, pumps and suspension joints, increasing long-term repair costs.
