Q: Q: Power steering

asked by on

I have a 2004 Subaru Legacy with 140k miles. When staring in you can hear a whining noise coming from the engine. I think it's the power steering because when I turn the steering wheel left or right the whining gets louder and you can barely get the tires to turn.

My car has 140000 miles.
My car has a manual transmission.

Hi There, This may be related to a failing power steering pump or low power steering fluid levels. As you may know, the power steering system uses a pump, normally driven by a belt. The pump supplies pressure as it is turned by your engine, and driver control is supplied by either the rack and pinion or a steering gear box. Fluid pressure from the pump is used to push against a piston. When the wheel is turned, pressure flows to one side and this piston moves. The piston is attached to the steering gears. As the hydraulic pressure does the work, the driver controls the direction by turning the steering wheel. The operation of this is accomplished with a very sensitive valve system called a rack and pinion. When the pump is beginning to fail or is low on fluid, you may hear this type of whining sound. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your power steering system.
