This high-pressure hydraulic hose is designed to carry pressurised power steering fluid between components of the steering system, helping maintain smooth, responsive steering assistance.
Manufactured as an original-style replacement, it is ideal for repairing leaking, deteriorated or damaged power steering hoses and restoring reliable hydraulic steering operation.
What Does the Power Steering Pressure Hose Do?
The pressure hose carries hydraulic fluid under high pressure from the power steering pump towards the steering rack.
This hydraulic pressure provides steering assistance, reducing the effort required to turn the steering wheel, particularly when parking or manoeuvring at low speeds.
Why Does It Fail?
Over time, exposure to engine heat, vibration and hydraulic pressure can cause the hose and its connections to deteriorate.
Common problems include:
- Cracked or hardened rubber hose sections
- Leaks around crimped fittings or connections
- Corrosion of metal pipe sections
- Damage caused by vibration or contact with nearby components
- Fluid loss resulting from ageing seals or fittings
When Should It Be Replaced?
Replacement is recommended if you experience:
- Visible power steering fluid leaks
- Falling power steering fluid levels
- Heavy or inconsistent steering assistance
- Whining noises from the power steering pump
- Cracked, swollen or damaged hose sections
Inspect the pump, reservoir, steering rack and associated connections before replacement to identify the source of any leak.
For left-hand-drive vehicles only.
Fitment may vary according to engine specification and steering system configuration. Confirm compatibility using the original part number or vehicle VIN before ordering.
Installation Notes
Power steering hoses must be installed with the correct routing and fittings to prevent leaks, rubbing or damage.
Following installation, refill the system with the Porsche-specified hydraulic fluid, bleed the steering system correctly and check all connections for leaks.
Porsche Cayenne 955 Power Steering Hoses & Hydraulic Steering Parts
The hydraulic power steering system fitted to the Porsche Cayenne 955 relies on high-pressure hoses to deliver fluid between the steering pump and steering rack.
Ageing hoses can develop cracks, leaks or damaged fittings, resulting in fluid loss, increased steering effort and potential damage to the power steering pump.

• System: Power-assisted steering - connects pump to steering rack (pressure line)
• Typical Usage: Replacement of old or worn pressure hoses, power steering overhaul or maintenance, repair of fluid leaks or loss of steering assist.
Over time, the factory power steering pressure hose can degrade due to heat, hydraulic stress, and age - leading to cracks, swelling or internal weakening. A failing hose may leak fluid, lose pressure, or collapse under load, causing hard steering, noisy pump operation, or complete loss of hydraulic assist. Replacing it with a correctly specified hose ensures reliable fluid delivery, restores steering assist performance, and protects other steering system components from undue stress.
