Detailed Description

This power steering hose assembly is built to match original equipment specifications for vehicles that use a combined pressure and return hose layout. It is a direct-fit replacement for applications such as the 2010-2013 Nissan 370Z, 2009-2013 INFINITI G37, 2007-2008 INFINITI G35, 2011-2012 INFINITI G25, and 2014-2015 INFINITI Q60, with fitment notes for non-Sport and OE-type steering configurations where listed.

By restoring the hose routing, brackets, and wear components specified for the vehicle, this assembly helps return the steering system to original condition. Sunsong 3403660 is a practical choice when you need a replacement for an OE-style pressure and return assembly on INFINITI and Nissan models.

Common Issues This Part May Address

  • Power steering fluid leaks from aged or damaged hose sections
  • Cracked, hardened, or heat-damaged hose material
  • Incorrect routing or fitment after prior repairs
  • Noise or steering effort caused by restricted fluid flow
  • Wear at brackets, sleeves, bushings, or grommet locations

Installation Notes and Tips

Verify the vehicle’s steering package and OE-type configuration before ordering, especially on INFINITI G35, G37, and Q60 applications with Sport or Active Steering exclusions. Confirm hose routing, end fitting style, and bracket locations against the original assembly. The pre-assembled design is intended to reduce installation time, but the system should still be inspected for fluid condition, mounting points, and any related wear before final assembly.

Quality Assurance

Each pressure hose is pressure-tested at the factory before shipment. The assembly is engineered to meet OE fit and function requirements, with pressure hose performance rated above original equipment standards for working pressure, burst strength, and tensile strength.
