Detailed Description

PWR part number 42-1389 is a hydraulic rack and pinion assembly designed as a direct-fit steering replacement for the Suzuki Grand Vitara and Suzuki XL-7 applications listed above. It includes inner tie rods, mounting brackets, and a gasket or seal, helping support a complete steering gear service where the original rack has wear, leakage, or inconsistent hydraulic performance. The assembly uses female 14 mm inlet and outlet fittings, a 36-spline input shaft, and a 16.8 mm shaft diameter for application-specific fitment. This part cross-references Maval 9383M for the same application.

Common Repair Uses

• Steering fluid leaks from the rack and pinion assembly
• Excessive steering play or loose on-center feel
• Noise or roughness during steering input
• Uneven or inconsistent steering response
• Wear in the hydraulic steering gear on Suzuki Grand Vitara or XL-7 models

Installation Notes and Tips

Verify line fitting size, input shaft spline count, and overall rack dimensions before installation. Mounting hardware is not included, so reuse or source the required fasteners as needed for the vehicle. After installation, bleed the hydraulic steering system and inspect for leaks, proper fluid level, and centered steering wheel position. Confirm alignment after steering component replacement.

Quality Assurance

PWR states that its racks and gears are engineered in the USA and tested for leaks, pressure, noise, and function before release. The 42-1389 is built to meet direct-fit replacement requirements for the listed Suzuki applications.
