Maval 96399M Power Steering Pump

Remanufactured Power Steering Pump for Mercedes-Benz SUVs

The Maval 96399M remanufactured power steering pump is built for Mercedes-Benz ML-Class applications that need reliable hydraulic steering performance. This aluminum-bodied pump is a direct replacement for select ML320, ML430, ML500, ML55 AMG, and ML350 models, with fitment-specific notes for pulley transfer during installation.

Maval’s Remanufactured Power Steering Pump line focuses on OE-style replacement coverage for steering systems that require accurate fluid flow, proper inlet and outlet connections, and consistent pressure delivery. The 96399M follows that approach with a quick-connect inlet, threaded outlet, and O-ring hose port design.

• Remanufactured power steering pump for Mercedes-Benz ML-Class applications
• Aluminum housing for durable steering system service
• Quick-connect inlet attachment type
• Threaded outlet with 16x1.5 outlet thread size
• O-ring hose port type for the hydraulic connection

Common Steering Issues Addressed

• Whining or groaning from a worn power steering pump
• Heavy or inconsistent steering effort at low speeds
• Hydraulic steering pressure loss from internal pump wear
• Leak-related pump replacement on Mercedes-Benz ML-Class vehicles
• Restoring steering response after pump failure or contamination

Installation Notes and Tips

Verify the OE pump design before installation, since two different factory pump designs are referenced for these applications. The pulley must be transferred using the proper pulley removal and installation tool, and the pump uses a press-on pulley attachment type. Confirm the quick-connect inlet, threaded outlet, and 16x1.5 outlet thread size before assembly.
