The power steering pump pressurizes fluid that the steering gear uses to reduce the effort needed to turn the wheel. Signs the pump may need replacing include a whining or groaning noise when turning, steering that feels heavy or inconsistent, and fluid leaking from the pump. These symptoms can also come from low or contaminated fluid, a leaking hose or a steering gear problem, so diagnose the system before ordering. If the pump is the cause, this 2003-2009 Toyota 4Runner power steering pump replacement installs in its place. See the "Vehicles it fits" section for the full list of applications.

What are signs the power steering pump may need replacing?
Whining or groaning when turning, heavy or uneven steering, and fluid leaking from the pump. Diagnose first, as low fluid, hoses or the steering gear can cause similar symptoms.
