First of all, let me say hello! This is the first time I've had to resort to the forum for advice. I have an 03 3.8L ls. My wife was driving home the other day following a truck/trailer. A large piece of concrete fell from the trailer and she tried to avoid it, but hit it with the edge of passenger front tire. It broke the a belt and created a bulge in tire. It would make an intermittent humming noise between 50-55. I went today and replaced the tire. Its still making the noise. No vibration and alignment is good. I changed the tire to the rear, but its still doing it. I'm thinking the wheel bearing was jarred. What do you guys think?
