Detailed Description

PWR part number 42-1091 is a hydraulic steering rack built for select 1996-2005 Audi and Volkswagen platforms. It is engineered for vehicles that require the specified steering gear configuration, including Audi A4 and A4 Quattro models with Koyo gear applications, Audi S4 coverage for 2000-2002, and Volkswagen Passat coverage across the listed years and chassis notes. This rack and pinion assembly is a practical replacement when the original steering gear shows wear, leakage, or inconsistent steering feel. This part cross-references BBB Industries 312-0133 and Cardone Reman 26-9006 for the same application.

Installation Notes and Tips

Verify the vehicle’s chassis note and steering gear type before ordering, especially on Audi A4 and A4 Quattro models with Koyo gear requirements. Mounting hardware and outer tie rods are not included, so reuse or source the correct related components as needed. Confirm inlet and outlet line fitting sizes, steering input shaft diameter, and end-to-end length against the original unit before installation.

Quality Assurance

PWR states that this steering rack is USA engineering approved and individually tested for leaks, pressure, noise, and function before release. The assembly includes seals and inner tie rods to support a complete steering gear replacement on the listed Audi and Volkswagen applications.
