This part cross-references Dayco 80623 and Gates 352188 for the same application.

What This Part Helps Address

• Power steering fluid leaks from a damaged pressure hose
• Steering effort caused by pressure loss in the hydraulic line
• Corrosion-related hose or tube deterioration
• Cracked, worn, or fatigued steering hose material
• Fitment issues from an incorrect replacement hose

Installation Notes and Tips

Verify the end fitting types and sizes before installation: 16 mm banjo on one end and 16 mm male O-ring on the other. Confirm hose length and routing against the original line on the vehicle, especially on 2005-2019 Toyota Tacoma and 2017 Toyota Hilux applications. Inspect mating surfaces, seals, and surrounding steering components for wear or contamination before installing the new hose.

Quality Assurance

Each Sunsong 3402456 hose is pressure tested before leaving the factory to confirm proper operation and installation readiness. The assembly is engineered to meet demanding pressure requirements and to provide corrosion resistance in harsh road conditions.
