• Loss of steering assist from pressure-side hose failure

Installation Notes and Tips

Verify hose routing, end fitting style, and vehicle application before installation. This assembly uses various end fitting types and does not include a power steering switch port. Inspect related steering components, mounting points, and surrounding heat exposure areas during replacement to help ensure proper fit and long-term service.

Quality Assurance

Each pressure hose is pressure-tested at the factory before shipment to confirm proper operation. The assembly is engineered to meet OE fit requirements and restore the worn hose assembly to original condition on compatible Nissan Frontier applications.
