Built to OE-Style Specifications

Sunsong 3403291 is a return hose assembly made to exceed original equipment performance standards in low-pressure steering return applications. The steel tubing is zinc electroplated to help resist rust and corrosion from humidity, road salt, water, and grime, while the rubber hose sections support routing in the steering system. This part cross-references Dorman - HELP 92599 and Gates 366024 for the same application.

Common Steering Issues This Part Can Address

• Fluid seepage or leakage at the steering return line
• Corrosion damage on the original return hose assembly
• Restricted or deteriorated hose routing between the gear and pipe
• Noise or inconsistent steering assist caused by a worn return line
• Fitment problems after replacing damaged steering plumbing on a G35 or 350Z

Installation Notes and Tips

Verify the vehicle application before installation and match the Gear To Pipe routing shown in the fitment data. Inspect adjacent steering components, brackets, grommets, heat shields, bushings, and protective sleeves for wear so the full return-line path is restored correctly. Confirm the 3/8 in. ID hose connections and 61 in. length against the original routing on the vehicle.
