Fitment and application details

This Sunsong power steering return line hose assembly, part number 3404910, is precision engineered for the specified Ford Focus routing and connection points. It is designed for the gear-to-cooler return path on 2007 Ford Focus and 2008 Ford Focus models, including 2008 vehicles built to 8/31.

Cross-reference part numbers include Edelmann 92880 and Gates 366336 for the same application.

Common issues this hose can address

• Power steering fluid seepage along the return line
• Cracked or aged hose material from heat exposure
• Corrosion on steel tubing in humid or salted-road environments
• Incorrect routing or fitment after prior repair work
• Restricted steering fluid return flow from a damaged hose assembly

Installation notes and tips

Verify the vehicle build date and routing before installation, especially on 2008 Ford Focus models noted through 8/31. Confirm the end fittings match the original connection style and inspect adjacent steering components, cooler lines, and mounting points for wear before reassembly. Properly route the hose to avoid contact with heat sources and moving parts.

Quality assurance

Sunsong states that this return hose assembly is manufactured to exceed original equipment performance standards for return-side steering service. The steel tubing is zinc electroplated to help resist rust and corrosion from moisture, road salt, grime, and other underbody exposure.
