A couple of months ago, I had a power steering fluid leak that was leaking pretty badly, so I took it to the dealership to have it fixed. They replaced the unit. Since I've gotten it back every time I make a turn, there's a squealing/humming noise coming from the front end. I brought it back, and they said there was nothing wrong...blah blah blah. Should I bring it somewhere else, or is this something that will go away over time? I love my car, but this noise is so obnoxious that it makes me feel self-conscious when I drive it.
