A couple of weeks ago on my 2000 Impala LS (3.8) I began to hear and feel whining & grinding whenever I turn especially tight low speed turns or from a parked position. My first step was to add more power steering fluid which seem to help out. Fast forward to this week it started doing the same thing and again added more fluid. This time though it did not go away completely and was still quite noticeable. Does this sound like the pump is going completely? How big of a repair is this for the backyard mechanic ? I was wondering if anyone had any experience with this.I did try doing a search for this but didn't have much luck. Any help would be appreciated.
I just refilled it again yesterday. I don't know exactly how much fluid is missing but each time I've checked it with cap/dipstick it's been bone dry so the fluid is going somewhere. It seems like I'm adding more every other day. It does seem to help and the noise does go away.
One of my power steering lines blew out in the Monte Carlo a few years ago and the pump ran low for about 10 miles. Even after replacing the line and topping off the fluid, the pump still makes more noise than it did before the line ruptured. To be honest, I think once the pump runs low in these cars, it's never quite the same again. It's annoying, but I don't think it's a problem unless it's failing to give you power assist.
Protip: If you don't know what you're doing, don't do it.
