Power steering rack mounting hardware plays a vital role in maintaining steering precision and chassis stability. Correct fastening ensures the steering rack remains securely mounted under load, helping maintain accurate steering response while reducing unwanted movement or vibration. Over time, original hardware can corrode, stretch, or become damaged during steering or suspension servicing, making replacement important for reliable operation and factory-correct assembly.
Produced as a genuine Porsche component, this pan head screw is manufactured using the correct material grade and dimensions required for Porsche steering systems. It is ideal for maintenance work, steering rack replacement, restoration projects, or replacing worn or missing original hardware.
Why Power Steering Rack Hardware Replacement Matters
Power steering rack mounting screws are exposed to constant vibration, steering loads, and suspension movement. Over time, hardware can corrode, stretch, or lose clamping strength, which may lead to steering movement, vibration, or reduced steering precision. Replacing worn or damaged fasteners helps maintain secure steering rack mounting and reliable handling performance.
When Power Steering Rack Screws Should Be Replaced
• During steering rack replacement or removal
• If original hardware is corroded or damaged
• When threads show signs of wear or stretching
• If steering vibration or movement is detected
• During suspension or front subframe servicing
• As part of restoration or preventative maintenance work

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: PAB423055, PAB423055C, PAB423055F, PAB423055G
• Location: Front steering system—rack & pinion/steering gear assembly mounted beneath the front sub-frame, linking to tie-rods and steering column.
The steering gear is the core of your vehicle’s directional control system. When internal components or seals wear or fail, you may experience looseness, creeping steering, increased effort or fluid leaks. Replacing the assembly restores sharp response, correct alignment and reliable front-end behaviour—helping preserve tyres, suspension components and driver confidence.
When to replace:
• Noticeable steering play, vague “centre-feel” or wanders on straight roads.
• Steering gear fluid leaks or visible damage to the rack housing.
• Front end has been impacted in a collision or major suspension components have been replaced.
• High-mileage vehicle where the original unit has served many years and may be nearing end-of-life.
• As part of a comprehensive steering/suspension service to avoid repeated labour for separate repairs.

The Porsche Genuine OE Inner Tie Rod / Steering Rack End (Part No. PAB423810A) is an original factory steering linkage component designed for Porsche Cayenne 9YA.1 and 9YA.2 (E3) models. It is the inner section of the tie rod assembly, connecting directly to the steering rack and working together with the outer tie rod end to transmit steering input to the wheels.
Sold individually, Fits left and right side (inner position).
Fits:

The inner tie rod transfers movement from the steering rack and pinion system to the outer tie rod and wheel hub, enabling accurate steering control.
As part of the steering linkage, it ensures precise wheel direction, stability, and alignment, while allowing articulation as the suspension moves.
Functions & Technical Role
• Steering transmission: Transfers movement from steering rack to wheels
• Alignment control: Maintains correct tracking and geometry
• Articulation: Works with ball joints for smooth suspension movement
• Stability support: Ensures responsive and predictable steering
• OEM precision: Engineered to Porsche tolerances for durability and performance
Tie rods are critical components linking the steering system to the wheel spindle, and wear can directly affect handling and tyre wear.
Fitment / Position on car:
• Fitting position: Front axle
• Location: Inner steering linkage (between steering rack and outer tie rod)
Inner tie rods are subject to constant load, vibration, and steering movement. Over time, wear can lead to:
• Loose or vague steering feel
• Uneven tyre wear
• Knocking or play in steering
• Poor alignment and handling
Replacing with a genuine Porsche OE rack end restores steering precision, improves safety, and ensures long-term reliability.

This OE match inner tie rod is a direct replacement for the original Porsche component used in the front steering system of Cayenne 9YA models (2018 onwards, including facelift 9YA.2). Installed between the steering rack and outer tie rod end, it forms the inner section of the steering linkage.
Sold individually, Fits left and right side (inner position).

Manufactured to OE specifications, it features a precision ball joint assembly and threaded shaft, allowing smooth articulation and accurate steering input transfer. The component is engineered for durability, using high-strength materials designed to withstand constant movement, load, and road conditions.
Positioned as a front inner tie rod (rack side), it ensures proper connection within the rack-and-pinion steering system. It is compatible with both left and right sides, making it a versatile replacement part supplied individually.
This component transfers steering input from the steering rack to the outer tie rod and ultimately to the wheel hub. It allows the wheels to turn precisely while maintaining alignment and stability, ensuring responsive handling and control.
Function
• Connects steering rack to outer tie rod assembly
• Transfers steering input to the wheels
• Allows controlled articulation via internal ball joint
• Maintains correct steering geometry and alignment
• Supports precise and stable steering response
Inner tie rods are subject to continuous steering movement and road stress. Over time, internal joints can wear, leading to looseness in the steering system. A worn inner tie rod can cause poor handling, uneven tyre wear, and reduced steering precision. Replacing it restores accurate steering response and vehicle stability.
When to replace
• Loose or vague steering feel
• Knocking or clunking from steering system
• Uneven tyre wear or alignment issues
• Excessive play in steering linkage
• During steering or suspension overhaul
