Product Details

This power steering pump is intended for Mercedes-Benz ML-Class vehicles across multiple engine and model configurations from 1998 through 2005. The fitment data includes 1998-2003 Mercedes-Benz ML320, 1999-2001 Mercedes-Benz ML430, 2002-2005 Mercedes-Benz ML500, 2000-2003 Mercedes-Benz ML55 AMG, and 2003-2005 Mercedes-Benz ML350. Because two different OE pump designs are noted, verify the existing pump style before installation.

The Maval New Power Steering Pump line is positioned as a replacement solution for steering repairs where the original pump has worn bearings, reduced hydraulic output, or noisy operation. Part number 96399MN is listed with pulley included and reservoir excluded, so it is suited to applications that reuse the vehicle’s existing reservoir setup.
