What This Hose Helps Address
- Power steering fluid leaks from a worn or damaged pressure line
- Loss of steering assist caused by pressure loss in the hydraulic circuit
- Noisy steering operation related to hose deterioration
- Corrosion-related hose failure from road salt and moisture exposure
- Poor fitment or routing issues from an incorrect replacement hose
Installation Notes and Tips
Verify the banjo and bubble flare end fittings, hose length, and bracket configuration before installation. Inspect mating surfaces, seals, and surrounding steering components for wear or contamination before connecting the new hose. After installation, fill and bleed the power steering system according to the vehicle service procedure to remove trapped air and confirm proper steering response.
Quality Assurance
Each Sunsong 3404870 hose is pressure tested before it leaves the factory to help ensure consistent performance and trouble-free installation. The hose is built to exceed original equipment performance standards for pressure, burst strength, and tensile durability.
