First of all, thank you to the person who posted instructions for posting, as the big red "Ask a Question" button was invisible to me.
Now that I've established my observational skills, here's my question:
My wife had the tires rotated on her 2007 Hyundai Santa Fe immediately before we went on a long road trip. After we left, we noticed a high-pitched whining sound at speeds of about 35-70 mph. It did not occur every time we hit that speed, and it generally seemed to go away after we'd been driving for about an hour.
We could make the noise stop every time by braking (as long as the pedal was depressed), or some of the time by turning (but only while the wheel was being turned). Occasionally, going over a particularly big bump could stop or start the noise.
My question is, what color is the car? Wait, no, my question is, is this likely to be the brakes, and if so, could it have been caused by the tire rotation?
