It started shortly after replacing the tires, and the frequency of the growl/whine increases as the tire speed increases only, not the rpm's. The noise disappears when the wheel is turned. I checked the CV boots and they look good. There doesn't appear to be anything rubbing, but it sounds a little like the tread on the tire rubbing on something. Tires are not worn, and don't show any signs of rubbing on anything.
What will cause a growling noise in the driver's side front end? on 2001 Pontiac Grand Prix
