Detailed Description
This Sunsong return hose assembly is made for steering systems that route fluid through the cooler tube on the Ford Edge and Lincoln MKX. The hose is built to exceed original equipment performance standards in return-side service, with steel tubing protected by a zinc coating to help resist humidity, road salt, water, and grime. Sunsong 3404880 is a practical OE-style replacement when the original return line shows wear, seepage, or corrosion.

What It Helps Fix
- Power steering fluid leaks at the return line
- Corrosion on the cooler tube or steel tubing
- Softening or deterioration of the return hose material
- Steering noise caused by low fluid level from a leaking line
- Loss of steering assist related to damaged return plumbing
Installation Notes and Tips
Verify the cooler tube routing and hose length before installation. This assembly is 111.8 inches long and uses an ID hose end fitting type. Inspect related steering components, clamps, and mounting points for wear or contamination before reassembly. Because this is a return-side hose, it is used in low-pressure service rather than high-pressure pump-to-rack routing.
Quality Assurance
Sunsong designs this return hose assembly to meet or exceed original equipment performance expectations for return-line use. The steel tubing is electroplated with zinc to improve resistance to corrosion and rust in harsh underbody conditions.
