If a leaking or worn high-pressure line is behind your power steering trouble, the Sunsong power steering pressure line hose assembly (part number 3404172) replaces it. This is the pressure line on the from-pump side, carrying pressurized power steering fluid from the pump to the steering gear. It is listed as a direct-fit replacement for the 2007-2012 Nissan Altima. See the Buyer's Guide tab for engine-specific application details.
Sunsong is a vertically integrated manufacturer that researches, develops and builds automotive fluid transfer hoses and lines. The company designs its products around what installers need and aims to go beyond industry quality standards. Sunsong builds its hoses for exact form, fit and function.
Signs this line may need replacing include power steering fluid leaking from the hose or its end fittings, a dropping reservoir level, a whining pump, or steering that feels heavier than normal. Other components can cause the same symptoms, so diagnose the cause before replacing the line.
