Detailed Description

This Sunsong power steering pressure line hose assembly, part number 3403773, is engineered for the Nissan Frontier power steering system where the line runs from the pump to the gear. The hose is precision built to match the original routing and connection points, with a 14 mm male O-ring on one end and a 16 mm banjo fitting on the other. Sunsong 3403773 also uses high-grade steel tubing with zinc coating to help resist rust and corrosion from humidity, road salt, water, and grime.

The hose construction is designed for pressure stability and long service life, with performance ratings that exceed original equipment standards. This part cross-references Nissan 497209BA0A for the same application.

What It Helps Address

• Power steering fluid leaks from a worn or damaged pressure hose
• Loss of steering assist caused by pressure line failure
• Corrosion-related hose deterioration on Nissan Frontier trucks
• Noise or stiffness in the steering system linked to restricted fluid flow
• Replacement needs after cracking, swelling, or fitting wear

Installation Notes and Tips

Verify the pump-to-gear routing, fitting sizes, and hose length before installation on your 2005-2015 Nissan Frontier. Inspect mating surfaces, seals, and adjacent steering components for wear or contamination before connecting the new line. Properly route the hose to avoid contact with heat sources or moving parts.

Quality Assurance

Each hose is pressure tested before leaving the factory to help ensure consistent operation and straightforward installation. The assembly is built to restore the original hose function and wear points on the vehicle.
