Keep steering effort light and consistent with the Sunsong Power Steering Pressure Line Hose Assembly 3402429, the high-pressure line that carries fluid from the power steering pump to the steering gear. It installs as a direct-fit replacement for the 2006-2010 Ford Explorer, 2007-2010 Ford Explorer Sport Trac, and 2006-2010 Mercury Mountaineer — see the "Vehicles it fits" section for engine-level fitment.
Signs the original line may need replacing include fluid leaks at the hose or fittings, whining from the pump, or stiff, hard steering. If a failed pressure line is the cause, this assembly replaces it.
