Detailed Description

This Sunsong pressure hose is built to restore the pressure line between the power steering pump and steering gear on the 2003-2006 Lincoln LS and 2003-2005 Ford Thunderbird. Part number 3402280 is manufactured to exact-fit dimensions and uses CSM hose material with steel tubing to help maintain steering system integrity under high pressure.

This part cross-references Gates 365488 for the same application.

Common Steering Problems It Can Address

• Power steering fluid leaks at the pressure line
• Loss of steering assist from a damaged hose assembly
• Noise or stiffness caused by pressure-side hose failure
• Corrosion-related deterioration of the steel tubing
• Fitment issues when replacing a worn Lincoln LS or Ford Thunderbird steering line

Installation Notes and Tips

Verify the end fittings, bracket location, and PS switch port layout before installation. This hose is specified for the to-gear position on the listed vehicles, so routing and connection points should match the original steering system configuration. Inspect related seals, mounting points, and surrounding lines for wear before completing the repair.
