Maval 96623M Power Steering Pump

Remanufactured Power Steering Pump for Mercedes-Benz

This Maval remanufactured power steering pump is built for Mercedes-Benz applications that require a replacement pump without a reservoir. Part number 96623M is listed for multiple GL, ML, R, E, S, CLS, CL, and S-Class models across 2006-2012, with pulley transfer required on many applications.

As part of Maval’s remanufactured power steering pump line, this unit is supplied as a service replacement for vehicles that need hydraulic steering pressure restored without replacing the reservoir assembly. The 96623M listing also cross-references Cardone Reman 21-120 for the same application.

• Remanufactured power steering pump for Mercedes-Benz steering systems
• Part number 96623M
• No pulley included
• No reservoir included
• Fits applications that require pulley transfer with the proper removal and installation tool
• Direct replacement coverage for select Mercedes-Benz GL450, GL550, ML350, ML550, R350, CLS550, E350, E550, S550, and related models

Detailed Description

Use this Maval power steering pump when the original unit is leaking, noisy, or no longer producing consistent hydraulic assist. The fitment list covers 2006-2012 Mercedes-Benz vehicles including GL450, GL550, ML350, ML550, R350, CLS550, CL550, E300, E350, E550, S400, S450, and S550 applications, with notes that some models require the pulley to be transferred from the original pump. Because this pump is listed without a reservoir, it is intended for vehicles that reuse the existing reservoir assembly.

Part number 96623M is a practical replacement for Mercedes-Benz owners servicing steering performance concerns on GL450 and ML350 platforms, as well as other listed chassis that use the same pump configuration.

Common Problems This Part Can Address

• Heavy or inconsistent steering effort
