Position on Vehicle: Mounted within the engine bay on the front accessory drive system, connected to the power-steering fluid reservoir and rack/column assembly.

•  Cross-Reference / Alternative Numbers: OEM number 996 314 050 03 (sometimes referenced as 99631405003); supersedes part number 996 314 050 02.

•  Applications: Replacement whenever the original pump shows symptoms such as whining noise, fluid leakage, reduced steering assist or erratic steering feel - helping to restore proper steering function and driver confidence.

The power steering pump is central to the assistive steering system, providing hydraulic pressure needed for effortless steering and precise control. When the pump begins to fail - through internal wear, leakage, or loss of hydraulic efficiency - drivers may experience noisy operation, heavier steering effort, or inconsistent responsiveness. Replacing it with a fresh unit restores hydraulic integrity, ensures consistent steering feel and prevents further wear on associated steering components.

When and why to replace:
Steering becomes notably heavier or varied in effort than expected.
Noticeable whining or groaning noise when steering, especially at low speeds.
Visible fluid leakage from the pump or associated lines/fittings.
After other steering components (rack, links) have been serviced - a failing pump would compromise the rebuild.
On high-mileage vehicles where original pump has been in service long and may be approaching end-of-life.

Fits:
Porsche 996

Porsche 981 Cayman

If you're serious about how your 996, 997, 986 Boxster, 987 Boxster, 987 Cayman, 991, 981 Boxster and 981 Cayman handles, you should upgrade the factory tie rods with an adjustable bump steer kit. There is one major drawback to the factory tie rods, bump steer. Bump steer results from a tie rod that is angled from the steering rack to the spindle. An angled tie rod end will have a larger horizontal travel distance than the rest of the suspension, compared to a level link. Rennline's adjustable bump steer kits solve this problem. Manufactured from 6061 aluminum and feature a turnbuckle design that allow each arm to be lengthened or shortened as needed to restore proper suspension geometry on a lowered Porsche. A number of spacers are also included and can be added or removed accordingly to get a level tie rod for your vehicles specific ride height. The FK Teflon-lined rod end bearings ensure precision handling and lock in your car’s alignment settings, ensuring predictable cornering under all conditions.

Note: 2 kits required per car. Rubber Boots not included but available separately.

Replacement Pipes (Steel) For RHD Steering Rack (Pair)
For Right Hand Drive Cars ONLY!  

Other than buying a completely new steering rack or having your existing steering rack refurbished, which are both very expensive options, we now offer replacement steering rack pipes which are normally not available separately, the two replacement pipes fit to the steering rack, these pipes normally deteriorate. The steering rack of a power-assisted car needs a hydraulic circuit: a pressure line (high pressure) from the power steering pump (or pump + reservoir assembly) to the steering rack, and a return line (low pressure) from the rack back to the reservoir (or pump return side).

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
  • Track Rods, U-Joints & Shafts

  • Pedal Control Parts
  • Power Steering Conversion Kits & Components
  • Steering Wheel Accessories & Hardware

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.
