Information
NEW steering rack, for LHD (Left Hand Drive) vehicles.
The steering rack is a vital part of steering system, converting steering wheel movement into precise control of the front wheels. Operating through a rack-and-pinion mechanism, the pinion gear on the steering column engages a toothed rack, translating rotation into lateral motion that turns the wheels. In power-assisted models, hydraulic or electric support reduces effort, delivering smooth, responsive, and accurate steering performance.
Fits:
Porsche Boxster 986 1997 - 2004
Porsche 996 1997 - 2004
Left Hand Drive Cars (like Europe)
Diagram ref no 1
• Position on Vehicle: Front steering rack assembly (LHD), connects the steering column to the tie-rods and front suspension – replacing the full rack unit including hydraulic or manual assist elements.
• Cross-Reference / Superseded Numbers: 996 347 011 11, also cross-references 99634701110 and 99634701107
• Typical Fault Symptoms: Leaking power-steering fluid, torn bellows, heavy or unresponsive steering at idle, non-returning steering wheel, noise when steering, partial loss of hydraulic power.
• Applications & Purpose: Ideal for vehicles where the original steering rack displays play, leakage or handling degradation. Using a new rack ensures secure fitment, proper steering geometry, fault-free assist and long-term durability.
Steering rack integrity is critical for accurate directional control, driver feedback and safe vehicle operation. Worn or leaking racks compromise the steering feel, introduce play, impair self-centering and may lead to erratic handling. Replacing with a new unit restores alignment, improves driver confidence and protects other steering components from premature wear.
When & why to replace:
• Observable fluid leak or torn boots on the steering rack.
• Heavy or unresponsive steering when idling or in low-speed manoeuvres.
• Steering wheel does not return properly after turning or shows play.
• Unusual noises when steering or juddering through front wheels.
• During any front-end service where removal of steering rack offers convenience.
• High-mileage vehicle or original rack still in use and nearing end of service life.

Information
Steering Rack / Steering Gear, for vehicles without rear axle steering, for LHD (Left Hand drive) cars.
This steering rack ensuring a direct-fit replacement and full restoration of front steering functionality. It converts driver input at the steering wheel into lateral wheel movement, providing accurate directional control and stable road-feel. It replicated original equipment specifications - including gearing tolerances, mounting interfaces and sealing - delivering factory-level performance.
Fits:
LHD (Left Hand drive) cars
Porsche 9YA Cayenne 2018 - 2024
* for vehicles without rear axle steering (option code: 0N1)
Diagram ref no 1
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.
• OE ref part numbers: PAB423055, PAB423055C, PAB423055F, PAB423055G
• Location: Front steering system—rack & pinion/steering gear assembly mounted beneath the front sub-frame, linking to tie-rods and steering column.
The steering gear is the core of your vehicle’s directional control system. When internal components or seals wear or fail, you may experience looseness, creeping steering, increased effort or fluid leaks. Replacing the assembly restores sharp response, correct alignment and reliable front-end behaviour—helping preserve tyres, suspension components and driver confidence.
When to replace:
• Noticeable steering play, vague “centre-feel” or wanders on straight roads.
• Steering gear fluid leaks or visible damage to the rack housing.
• Front end has been impacted in a collision or major suspension components have been replaced.
• High-mileage vehicle where the original unit has served many years and may be nearing end-of-life.
• As part of a comprehensive steering/suspension service to avoid repeated labour for separate repairs.
