Detailed Description

This PWR rack and pinion assembly is built for Mercedes-Benz GL-Class and ML-Class vehicles that use hydraulic steering. The unit includes inner tie rods, mounting brackets, and seals, and it is configured with female 11 mm inlet and outlet fittings, a 54-spline input shaft, and a 3.11 lock-to-lock ratio. PWR 42-2323 cross-references Cardone New 97-4022 for the same application.

Common Repair Symptoms

• Steering play or looseness at the wheel
• Fluid leakage from the steering gear
• Noise during steering input
• Uneven or inconsistent steering response
• Wear-related failure in the original rack and pinion assembly

Installation Notes

Verify hydraulic power steering configuration and confirm whether the vehicle is listed with or without speed sensitive steering before ordering. Compare the input shaft spline count, shaft diameter, and line fitting sizes to the original unit before installation. Because mounting hardware is not included, reuse or source the required fasteners as needed during replacement.

Quality Assurance

PWR states that its pumps, racks, and gears are tested for leaks, pressure, noise, and function, and that this unit is USA engineering approved. That testing helps support consistent steering performance on Mercedes-Benz GL350, GL450, GL550, ML350, ML450, ML550, GL320, ML320, ML63 AMG, and ML500 applications covered by the fitment data.
