Detailed Description

Sunsong 3402558 is a power steering pressure line hose assembly made for 2005-2007 Ford F-250 Super Duty and 2005-2007 Ford F-350 Super Duty trucks. It uses 16 mm and 18 mm swivel O-ring ends for a precise OE-style connection, and the 27.9-inch hose length supports proper routing in the steering system. The hose construction uses CSM material, while the tubing is formed from high-grade steel with a zinc coating to help resist corrosion from humidity, road salt, water, and grime. This part cross-references Dorman - HELP 80446 and Gates 363950 for the same application. Part number 3402558 is a practical replacement when the original pressure line shows wear, leakage, or corrosion.

Common Steering Issues It Can Address

  • Power steering fluid leaks from a damaged pressure hose
  • Hard or inconsistent steering caused by pressure loss
  • Corrosion on the original steel line
  • Cracked or deteriorated hose material
  • Fitment problems from a bent or incorrect replacement line

Installation Notes and Tips

Verify the fitting sizes and hose routing before installation. This assembly does not include a bracket and does not include a power steering switch port. Inspect related seals, mounting points, and adjacent steering components during replacement to help ensure a clean installation on your Ford F-250 Super Duty or Ford F-350 Super Duty. Confirm the vehicle year and application match part number 3402558 before ordering.
