Keep power steering fluid moving back through the system with the Sunsong power steering return line hose assembly, part number 3404309. It is a direct-fit replacement for the 2004-2006 Lexus RX330 and serves the intermediate pipe position, carrying fluid on the low-pressure return side of the power steering circuit.
Sunsong is a vertically integrated manufacturer that researches, develops, and builds automotive fluid transfer hoses and lines, designing its products around what installers need and to deliver exact form, fit, and function.
Signs this line may need replacing include power steering fluid seeping or dripping from the hose or its connections, a steadily dropping fluid level, or a pump that whines when fluid runs low. If a leaking return line is the cause, this assembly replaces it; pinpoint the source of the leak before ordering. See the Buyer's Guide tab for complete application details.
