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.

OE Match power steering pump hose, a replacement component for repairs involving an ageing or leaking pump hose.
Fits
Porsche 928 1978-86
Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
The hose carries fluid within the hydraulic power steering circuit at the pump. Its condition and connections matter when investigating fluid loss or servicing the steering hydraulics. This component is a hose, rather than a replacement pump or steering cooler.
Functions
- Provides a fluid passage within the pump circuit.
- Contains steering fluid along its installed route.
- Replaces a deteriorated hose when leakage or damage has been confirmed.
Technical Details
- Brand: OE Match.
- Part reference: 92834744501.
- Component: power steering pump hose.
- Listed engine applications: 4.5L and 4.7L, subject to the model and year details above.
Symptoms of Fault
- Wet patches or seepage around the hose and its connections.
- A falling power steering fluid level.
- Visible cracking, hardening or swelling of the hose.
- Increased steering effort or pump whining associated with low fluid.
These symptoms do not establish that the hose is the cause. Inspect neighbouring connections, seals and hydraulic components before deciding which parts require renewal.
Why Replacement Matters
Renewing a confirmed leaking or damaged hose addresses a source of fluid loss. Check adjoining fittings and supporting components during the repair, as an unresolved leak elsewhere can leave the same symptoms after installation. OE Match focuses on replacement components for Porsche applications, with original references and vehicle specifications used to assess suitability.
FAQs
Should other hoses be renewed at the same time?
Inspect them individually. Further replacement may be appropriate where neighbouring hoses also show deterioration or leakage.
Is flushing required?
Assess the fluid condition and follow the vehicle-specific service procedure. Flushing is particularly relevant if contamination is present.
What should be checked during fitting?
Confirm the routing and connections, avoid twisting the hose and use the specified seals or sealing washers where required. Check the completed repair for leaks.

Professional Installation Required
Each hose section is supplied with a dedicated crimp sleeve. Installation must be carried out by a professional to ensure correct crimping and secure sealing.
Complete OEM replacement hoses are expensive. This repair kit provides a practical and cost-effective alternative by replacing only the flexible rubber hose sections while allowing you to reuse the original steel pipe assemblies.
What This Repair Kit Does
This kit replaces the flexible sections of the low-pressure power steering return line. The return hose carries fluid back to the reservoir and operates at low pressure, making it suitable for high-quality reinforced silicone replacement hose.
By installing this repair kit, you can:
• Eliminate leaks from aged rubber sections
• Retain the original factory steel hard lines
• Avoid the cost of complete OEM hose assemblies
• Restore safe and reliable power steering operation
Why Upgrade to This Silicone Repair Kit?
Significant Cost Saving
Original Porsche 928 power steering return hoses can be very expensive. This
repair solution allows you to refurbish the existing assembly at a fraction of
the cost.
High-Strength Silicone Construction
Manufactured from very strong, heat-resistant silicone, the replacement hose
sections provide improved durability over ageing factory rubber.
Designed Specifically for 928 Applications
This kit is engineered to suit the correct hose diameters and routing used on
Porsche 928 S2, S3, S4, GT and GTS models.
Safety Reminder
Power steering fluid is flammable. It is important to regularly inspect return
hoses and address leaks immediately to reduce fire risk within the engine bay.
