Detailed Description

Built for Ram heavy-duty steering service, Sunsong 3405070 is a power steering pressure line hose assembly that follows the original hydroboost-to-gear layout on 2011-2012 Ram 2500 and Ram 3500 trucks. The hose is manufactured to exceed original equipment performance standards, with pressure capacity and tensile strength specified for demanding steering system operation. Sunsong 3405070 also uses zinc-coated steel tubing to help resist road salt, moisture, grime, and other underbody exposure common in daily and work-truck use. This part cross-references Dorman - HELP 80886 for the same application.

Common Problems This Part Can Address

  • Power steering fluid leaks from a worn or damaged pressure line
  • Loss of steering assist caused by pressure loss in the hose assembly
  • Corrosion-related hose deterioration on exposed underbody routing
  • Improper fit or routing after a failed original hose replacement
  • Noisy or inconsistent steering operation linked to pressure line wear

Installation Notes and Tips

Verify the hydroboost-to-gear routing and end fitting sizes before installation. Inspect adjacent steering components, brackets, seals, and connection points for wear or contamination before connecting the new hose. Properly route the line to avoid contact with heat sources, moving suspension parts, or sharp edges, and confirm all fittings are clean before assembly.

Quality Assurance

Each Sunsong pressure hose is pressure tested before it leaves the factory to help ensure consistent operation and straightforward installation. The hose assembly is precision engineered for exact fit and built to restore worn steering plumbing on Ram 2500 and Ram 3500 trucks.
