Detailed Description

This Sunsong power steering return hose is built to replace the return line between the steering gear and cooler on select Nissan trucks and SUVs. It is designed around the original routing and connection points for 2005-2017 Nissan Frontier, 2005-2015 Nissan Xterra, and 2005-2012 Nissan Pathfinder, making it a direct-fit solution for common return-side steering hose service. The hose assembly uses CSM construction and is rated for low-pressure, high-temperature operation, with a maximum working pressure of 250 psi. Sunsong 3405333 is a practical replacement when the return hose is leaking, cracked, or no longer holding proper fluid flow in the steering system.

This part cross-references Gates 352827 for the same application.

What It Helps Fix

• Power steering fluid seepage from the return line
• Cracked or hardened hose material from heat and age
• Steering fluid loss caused by worn hose connections
• Noisy steering operation related to low fluid level
• Return-line deterioration on Nissan Frontier, Xterra, and Pathfinder models

Installation Notes and Tips

Verify the vehicle’s steering gear-to-cooler routing before installation and compare the hose ends to the original part. Inspect nearby clamps, cooler lines, and connection points for wear or contamination before filling and bleeding the system. After installation, check for leaks with the engine running and the steering turned through full lock-to-lock cycles.
