Product Details

This Sunsong power steering return hose is made to restore the return side of the steering system on the Ford Focus. Part number 3403919 is built to OE performance standards and is suited for the lower-pressure portion of the hydraulic steering circuit, where heat and fluid exposure can accelerate wear.

Installation Notes

Verify the banjo fitting size, hose routing, and overall length before installation. Inspect the steering system for worn seals, damaged clamps, or contaminated fluid, and replace any related components that show wear. Confirm the hose follows the original path to avoid contact with moving parts or hot surfaces.
