Information
Power Steering Rack – Left Hand Drive (LHD)
The power steering rack is a critical steering component responsible for converting steering wheel input into precise, controlled movement of the front wheels. By using hydraulic pressure, the rack significantly reduces steering effort while maintaining the sharp, responsive feel Porsche is known for.

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.

Steering rack ball joint end.
These OE Match ball joints mount at the outer ends of the front steering tie rods and install with no modifications, delivering factory-spec fit, durability, and restored steering precision.
Fits:
Porsche 970.1 Panamera 2009 - 2013
Porsche 970.2 Panamera 2014 - 2016
Diagram ref no 7 (LEFT) and 8 (RIGHT).
These ball joints connect the steering rack to the wheel hubs, allowing smooth pivoting while transferring steering input directly to the wheels. They ensure proper steering geometry, reduce play, and maintain even tire wear, giving you precise control at all speeds.
Over time, ball joints wear due to road impacts, vibration, and exposure to the elements. A worn joint can cause loose steering, clunking noises, uneven tire wear, or even unsafe handling. Replacing them guarantees a direct fit, correct articulation, and long-lasting durability.

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: 97034701102, 97034701103, 97034701104, 97034701105, 97034701106, 97034701127, 970347011BX, 970347011CX, 970347011DX, 970347011H,
• Location: Front steering system - the rack and pinion (or steering gear) assembly sits beneath the engine bay/front subframe, linking the tie rods to the steering column.
The steering gear assembly is central to safe and accurate vehicle control. When the internal components or seals degrade, drivers may experience play, wandering, steering drift or increased effort — all of which compromise control. Replacing the rack ensures restored alignment of steering geometry, consistent feedback and proper behaviour under load.
When to replace:
• Noticeable steering play, loose feeling, or uneven response when turning the wheel.
• Leaks from the rack housing or evidence of hydraulic fluid (for power-assist racks), indicating seal failure.
• Vehicle exhibits wandering or drifting on straight roads, suggesting internal wear or rack mounting issues.
• After collision damage to the front end or steering linkage, when replacing associated components would make rack change more efficient.
• High-mileage vehicle where the original rack is nearing the end of its service life and proactive replacement prevents unexpected failure.
