Supply the hydraulic pressure your power steering system depends on with the Atlantic Automotive Engineering Remanufactured Hydraulic Power Steering Pump 5517, a unit that is 100% tested before it ships. It fits many Mercedes-Benz models, among them the 2010-2012 Mercedes-Benz GL450, 2010-2012 Mercedes-Benz GL550 and 2010-2011 Mercedes-Benz ML350, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for engine details and the full list of vehicles.
- Remanufacturing process: Each pump is taken apart and cleaned, and every wear component is replaced, with the aim of OE performance and durability.
- Inspected and tested: Every unit is 100% inspected before shipment and hydraulically tested under load in the USA. It is built under the Manufactured Again Certified quality process.
- What's included: The pulley comes with the pump. A reservoir is not included.
- Protective finish: Each unit is electrostatically painted with automotive-grade paint.
AAE highly recommends replacing the steering fluid reservoir along with the pump, because a clogged reservoir can starve the replacement pump of fluid. Signs a pump may need replacing include a whining or groaning noise when turning, heavier steering effort, and fluid leaking at the pump. If a worn pump is the cause, this unit replaces it. Diagnose the system before you replace any parts. If your 2010-2012 Mercedes-Benz GL450 needs a new GL450 power steering pump, this unit is listed for it.

Frequently Asked Questions
Is this the right ML350 power steering pump for a 2010-2011 Mercedes-Benz ML350?
It is listed for the 2010-2011 Mercedes-Benz ML350. Check the "Vehicles it fits" section for engine details and the other listed applications.
Does this pump come with a reservoir?
No. The pulley is included, but the reservoir is not. AAE highly recommends replacing the steering fluid reservoir with the pump, because a clogged reservoir can starve the replacement pump.
How is this pump remanufactured?
Each unit is disassembled and cleaned, and all wear components are replaced. It is then 100% inspected and hydraulically tested under load in the USA before shipment.
What does a power steering pump do?
It is a hydraulic pump. It pressurizes power steering fluid and sends it to the steering gear, which helps reduce the effort needed to turn the steering wheel.
What are signs a power steering pump may need replacing?
Common signs include whining or groaning when turning, heavier steering effort, and fluid leaking at the pump. Diagnose the cause first, because other steering parts can cause similar symptoms.
