Detailed Description

This Sunsong power steering return line hose assembly is engineered for Toyota 4Runner models with gear-to-cooler routing from 2010 through 2019, excluding Dynamic Suspension applications. Sunsong 3404461 is built to restore the return-side fluid path with the correct length and hose configuration for the listed fitment. The assembly is intended for the lower-pressure side of the steering system, where heat and fluid exposure are common.

High-grade steel tubing with zinc electroplating is used to improve resistance to corrosion and rust from humidity, road salt, water, and grime. The hose assembly is precision engineered for exact fitment and is made to restore wearable components to original condition where applicable. This part cross-references Toyota OE numbers 4440660020 and 4440660021 for the same application.

What This Part Helps Address

• Power steering fluid seepage from a worn return hose
• Cracked or hardened hose material from heat and age
• Corrosion on exposed steering line tubing
• Incorrect routing or fitment after prior repairs
• Noise or steering performance issues caused by return-line restriction

Installation Notes and Tips

Verify vehicle fitment by year, model, and steering configuration before installation. This hose fits the gear-to-cooler position on 2010-2019 Toyota 4Runner models and does not apply to Dynamic Suspension vehicles. Inspect adjacent clamps, seals, and mounting points for wear before reassembly, and confirm the line is routed without kinks or contact with hot or moving components.

Quality Assurance

Sunsong manufactures this return hose assembly to exceed original equipment performance standards for return-side steering service. The construction combines corrosion-resistant tubing with application-specific fitment details to support reliable replacement on the listed Toyota 4Runner vehicles.
