Power steering whine - how to quiet
I recently replaced my old power steering pump and all three hoses with a remanufactured pump and new hoses (the old pump was leaking).
My old pump was original equipment and ran quietly. The new pump is quite noisy, to the point when I'm driving straight and going through the gears with the windows up I can hear the pump whining.
I remember seeing on here some solutions to this problem whereby something was added to the fluid and it quieted things down.
My searches here only turned up a couple of people suggesting the use of rear end friction modifier in the steering fluid.
The job was properly done, and I'm using type-F fluid (as always). I've run my pump out of fluid years ago and then it really started whining - I have enough fluid in it now.
Can anyone shed some light on this situation for me? A safe additive to kill some of the noise?
