Atlantic Automotive Engineering Power Steering Pump P/N:50138N
Keep the steering light and responsive on your Mercedes-Benz with the Atlantic Automotive Engineering Power Steering Pump (MPN 6817). It drops in as a direct-fit replacement for the 2002-2006 Mercedes-Benz CL500, 2002-2006 Mercedes-Benz CL55 AMG, 2002 Mercedes-Benz CL600, 2002-2006 Mercedes-Benz S430, 2002-2006 Mercedes-Benz S500, 2002 Mercedes-Benz S600, and 2006 Mercedes-Benz S350.
A power steering pump pressurizes the power steering fluid to supply the hydraulic assist that makes the wheel easier to turn. When the original pump wears, you may notice a whine or groan while turning, heavier-than-normal steering effort, or fluid weeping from the pump — signs the pump may need replacing.
If a whine or stiff steering appears, diagnose the system first, since fluid level, the belt, or the steering gear can produce similar symptoms.
