Detailed Description

This power steering hose assembly is designed for drivers and technicians servicing Infiniti steering systems that require an OE-type pressure and return assembly. Sunsong 3403674 follows original equipment specifications for fit and routing, making it a practical replacement for a worn, leaking, or damaged steering hose assembly on the 2007-2008 Infiniti G35 and 2009 Infiniti G37.

This part cross-references Nissan/Infiniti OE number 49710JK61A for the same application.

What It Helps Fix

• Power steering fluid leaks from cracked or worn hose sections
• Loss of steering assist caused by pressure-side hose failure
• Noisy or inconsistent steering operation related to hose deterioration
• Improper hose routing or fit after prior repairs
• Service delays from replacing pressure and return hoses separately

Installation Notes and Tips

Verify vehicle application before installation. This assembly is listed for 2007-2008 Infiniti G35 and 2009 Infiniti G37, with the 2009 G37 application noted for vehicles built to 4/30. Inspect surrounding steering components, brackets, and seals during service so the replacement assembly can be installed on a clean, properly prepared system.

Because the hose assembly is pre-assembled to OE-style specifications, it is intended to reduce installation time compared with sourcing individual hose sections. Confirm all connection points match the original routing and fittings before filling and bleeding the power steering system.

Quality Assurance

Each pressure hose is pressure-tested at the factory before shipment. The assembly is built to exceed original equipment performance standards for working pressure, burst pressure, and tensile strength, supporting dependable operation after installation. Sunsong 3403674 is engineered as a direct OE replacement for the listed Infiniti applications.
