Hi guys. My automatic '99 Chevy is low mileage (45,000). Don't laugh.;) Well maintained.
Anyway, I had the power steering pump replaced 3 days ago with the assurance that the irritating whinning would disipate within a couple days as the new pump "became lubricated". Needless to say... the noise continues just as before. I wonder if the fluid system should have been flushed, bleed, and refilled?
The noise I speak of is constant, especially in drive. Less in park. Its pitch changes (becomes louder also) at the beginning of shift changes. The noise is less noticable at high speeds (greater than 45mph). A "secondary" noise is also apparent in park, which I assume is also the pump. BTW - The car was tuned about a year ago.
Any suggestions, guys?
