Car emits a low grating humming noise coming from the driver's side engine area roughly behind the air box. Noise goes away completely if the steering wheel is engaged (turned). Noise happens while parked or driving and stops as soon as you turn the wheel in either direction.

No noise where the power steering reservoir or pump are (passenger side). Power steering working fine with no noise while turning.

Please help. Thank you.

Hello,

This happens for two reasons either the fluid is worn out or the pump is. I would try the fluid first. Here is a video to show you how to flush the system:

If that does not do the trick the pump will be next this guide will give you an idea of what you are in for when doing the job.

Please let us know what happens.

Cheers, Ken
