Durable Construction and Precise Fitment

This power steering pressure line hose assembly (part number 3403955) features a robust CSM (chlorosulfonated polyethylene) hose material that resists heat, abrasion, and hydraulic fluid degradation. The hose measures 61.5 inches (1562 mm) in length, providing an exact replacement for the original equipment on compatible Ford Expedition and Lincoln Navigator vehicles. Both ends are equipped with male o-ring fittings—11 mm on one end and 14 mm on the other—ensuring a secure, leak-free connection within the power steering system. The absence of a bracket and power steering switch port simplifies installation and compatibility.

Application and Common Issues Addressed

• Replacement for worn or leaking power steering pressure hoses

Installation Notes and Tips

When installing the Sunsong 3403955 power steering pressure line hose assembly, verify the hose length and fitting sizes match your vehicle’s specifications. Ensure both male o-ring fittings (11 mm and 14 mm) seat properly to prevent leaks. Since this assembly does not include a bracket or power steering switch port, confirm existing mounting points and switch connections are compatible. Follow manufacturer torque specifications for fittings to maintain system integrity.
