Diagram ref no 1

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.
