Keep hydraulic steering assist doing its job with the TERREPOWER (formerly BBB Industries) Power Steering Pump N990-1054, a new power steering pump for the 2003-2005 Mercedes-Benz ML350 and the 2004-2005 Mercedes-Benz ML500 that drops in as a direct-fit replacement. The pump pressurizes power steering fluid and sends it to the steering gear, supplying the hydraulic assist that reduces the effort needed to turn the wheel.
Signs a power steering pump may need replacing include a whining or groaning noise when turning, steering that feels heavy or stiff, or fluid leaking from the pump. These symptoms can also come from other parts of the steering system, so diagnose the cause before replacing the pump. If a failed pump is the cause, N990-1054 replaces it.
For engine and configuration details on each application, see the "Vehicles it fits" section. Follow the vehicle service information for installation, and fill and bleed the system with the power steering fluid specified for your vehicle.
