Detailed Description

This Sunsong power steering pressure line hose assembly, part number 3402508, is made for Toyota Tundra trucks equipped with the tow package and matches the original routing and connection style for the application. The hose uses a 16 mm banjo fitting on one end and a 16 mm male O-ring fitting on the other, with a 67.9-inch overall length for proper system alignment. Sunsong builds this hose with high-grade steel tubing and zinc plating to resist rust and corrosion from humidity, road salt, water, and grime. This part cross-references Four Seasons 55229 for the same application.

Common Problems This Part Can Address

• Power steering fluid leaks from a worn or damaged pressure hose
• Steering noise caused by pressure loss in the hydraulic line
• Hard or inconsistent steering effort from hose deterioration
• Corrosion-related failure in the original steel line
• Fitment issues when replacing a hose that no longer seals correctly

Installation Notes and Tips

Verify the vehicle build date and tow package configuration before ordering, especially for 2004 Toyota Tundra models built through 3/30. Confirm both end fittings match the original hose before installation, and inspect the steering system for contamination or wear that could affect the new line. Properly route the hose to avoid contact with moving or hot components.

Quality Assurance

Each Sunsong 3402508 hose is pressure tested before it leaves the factory to help ensure consistent sealing and operation after installation. The hose assembly is engineered to exceed original equipment performance standards for pressure, burst strength, and durability.
