This steering gear (rack & pinion / steering gear assembly) originally developed for the Porsche Cayenne (955/957) series. Its purpose is to convert driver steering-wheel inputs into controlled lateral movement of the front wheels, ensuring accurate directional control and stable handling. Built to original equipment standards and engineered for precise fitment, it delivers enduring performance, smooth steering and dependable durability.

• Location: Front axle, steering rack assembly mounted beneath the front subframe, linking the steering column and tie rods.
The steering gear plays a vital role in ensuring precise handling and safe directional control. Over time, internal wear, seal failure, or corrosion can lead to fluid leaks, increased play, or heavier steering effort. A worn or leaking rack affects steering response, stability, and overall driving comfort. Replacing it with an OE-Match unit restores smooth operation, tight steering feel, and the factory performance your Porsche Cayenne was designed to deliver.
When and why to replace:
• Noticeable looseness or vibration through the steering wheel.
• Power-steering fluid leaks or visible damage to the rack housing.
• Uneven steering effort or noise when turning.
• Vehicle wandering or pulling despite correct wheel alignment.
• During major suspension or front-axle service for full system refresh.
• Preventative maintenance on high-mileage vehicles to avoid sudden failure and costly repairs.

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. If you choose to replace only the steering rack and, upon return of your exchange unit, we discover that the rack bar is scored or contaminated with swarf, this indicates that debris is present in the system. In such cases, we advise replacing the pump as well.
Please note: if we have advised that there is swarf in the system and you choose not to replace both components, any future warranty claims related to this issue will not be valid.
All racks come with 2 Years warranty!!
The most common power steering faults are:
- Leaking power steering
- Torn Gators
- Hard to steering when idling
- Hard to steering one-way
- Steering-Wheel not self-centering
- Noise when Idling
- Noise when steering
- Judders when steering
- Loss of all power in steering
- Semi-Loss of power in steering
- Electric steering problems

What This Product Does
The rack changes steering-wheel rotation into sideways movement, which the tie rods transmit to the front wheels. Bellows cover the moving rack ends, helping to keep contaminants away from the protected components.
Functions
- Converts rotational steering input into linear travel.
- Transfers rack movement through the tie rods.
- Covers the rack ends with protective bellows.
Technical Details
- Supplied assembly: new steering rack, tie rods and bellows.
- Drive configuration: Right Hand Drive (RHD).
- Internal diagram references: 99334701204 and 993347012DX.
- Diagram notes for both references specify associated positions 7, 8, 9 and 10, plus pressure line 99334745804. These notes do not establish that those additional components are included.
Symptoms of Fault
- Hydraulic fluid leakage or repeated fluid loss.
- Split steering gaiters.
- Heavy steering at idle or unequal effort between directions.
- Poor steering-wheel return towards centre.
- Noise at idle or during steering.
- Judder, looseness or knocking through the wheel.
- Partial or complete loss of steering assistance.
Similar symptoms can originate in the pump, joints, bushes or suspension. Electrical steering problems require separate diagnosis rather than assuming that rack replacement will resolve them.
Why Replacement Matters
Renewing a diagnosed worn or leaking rack addresses deterioration within the assembly. Pump replacement alongside the rack is strongly recommended: circulating swarf can damage either component. Scoring or metal contamination found when an exchange rack is inspected indicates debris within the system, so the pump should also be assessed and replaced as advised.
FAQs
Are tie rods and bellows supplied?
Yes, both are included with this assembly.
Is wheel alignment needed afterwards?
Arrange wheel alignment following installation.
What else should be checked?
Inspect the pump, fluid, pipework, mounts and related joints. Follow the correct flushing and refilling procedure, using the specified fluid.
