Hello everyone first post here. Nice site. Got a question for ya. I put in a new ACDelco professional power steering pump in the other day...but it whines a little and you can really hear it more at higher rpms. It's not real loud but I am concerned it is an issue as my steering is a tad stuff. Is this whine normal? This is my second p/s pump and both whined the same. Starting to think the hydro brakes might be causing the whine. Thanks for any input!
