Sunsong 3401235 power steering pressure line hose assembly for the 2003-2009 Toyota 4Runner and other vehicles carries power steering fluid under pressure to the steering gear.
A fluid leak at the hose, a whine when turning or heavy steering can mean the pressure line is wearing out. These signs alone do not prove this hose is the problem, since a weak power steering pump can cause them too.
This hose assembly fits the 2003-2009 Toyota 4Runner and the 2003-2009 Lexus GX470. This listing is one hose, and the 2003-2009 Toyota 4Runner takes one.
