Product Details

The AAE New Power Steering Pump Kit line is focused on OE-style hydraulic steering service parts built for proper operation and fitment. Part number 5517NKTB is intended for Mercedes-Benz vehicles with speed-sensitive power steering and includes the major components commonly replaced together during steering pump service. This part cross-references Genuine 0004602683 for the same application.

Compatible With 2010-2012 Mercedes-Benz GL450, N/A; 2010-2012 Mercedes-Benz GL550, N/A; and 2010-2011 Mercedes-Benz ML550, N/A.

Common Issues This Kit May Resolve

• Whining or groaning from the power steering pump
• Heavy or inconsistent steering effort
• Hydraulic fluid flow problems caused by worn pump components
• Leak-related steering performance loss at the pump or return side
• Restricted flow from a contaminated reservoir screen when the reservoir is reused

Installation Notes and Tips

Flush the steering system and refill it with an OE-approved power steering fluid before returning the vehicle to service. Replacing the reservoir with the pump is recommended when the original screen is restricted, since a clogged reservoir can starve the replacement pump and shorten service life. Verify vehicle configuration and part number 5517NKTB against the existing unit before installation.
