Recently I just bought a 2006 suzuki aerio SX AWD auto transmission. The cars runs fine, no problem. Just a day or 2 ago I started hearing a noise inside but it may be comming from outside. It sounds like a metal rubbing on a something. This noise only comes when I go on a rough road on the highway and then once the finished paved road comes back it will stop. Also sometimes on rough road if the speed is low the noise will stop. Other than this the car runs fine. If I were to match the noise to something I would say it sounds like metal touching a grinding wheel. If you are sitting inside it is right in the from underneath you the noise. It only cones on for 1min and then goes away. If I am driving on a 40min trip it happens 3 times for a min each on rough roads. Sorry I could not place more info.
here is an update. It sounds like it coming from the front right wheel. Whats happening is that when I go on rough road the noise starts at speed of around 60mph. Then when I apply the brakes it stops. When I let go of the brakes and I am still on the rough road the noise is back. Any ideas.
