    Default Power steer whine

    What causes power steer whining? My BIL GC has developed a whine. Is this normal wear and how does one fix it?

    Replace all PS fluid with manufacturer's spec and bleed properly ensuring no air is present.

    Thanks, that rings a bell. The mechanic has advised that the pump might to be reconditioned or replaced. Any merit in that?

    Would that be the sound of hydraulic fluid being dumped through a pressure relief valve?
