Part number 3404700 is also pressure tested at the factory before release, supporting consistent installation and operation on Infiniti FX35, FX37, and QX70 steering systems.

What This Part Helps Address

• Steering fluid leaks from a worn or damaged pressure hose
• Loss of hydraulic steering assist
• Noise or stiffness caused by restricted fluid flow
• Corrosion-related hose deterioration
• Fitment issues from an incorrect hose configuration

Installation Notes and Tips

Verify the end fittings, hose length, and routing before installation. This assembly does not list a bracket or power steering switch port, so confirm your vehicle’s original layout matches the part before removal. Inspect related seals, clamps, and mounting points for wear, and flush contaminated power steering fluid if the system shows signs of debris or discoloration.
