First, I need to know the engine size - 1.8L, 2.0L, 2.4L, or 2.4L Turbo
Second, can you describe the noise - squealing, screeching, whining, roaring, growling, grinding, etc.
Does the noise seem to come from the engine compartment or more from either the right front or left front tire?
Is the noise constant, or does it seem to be in correlation with wheel/vehicle speed
Does it make the noise while stopped and idling?
Please remember that I am not there and cannot listen to the sound or test drive the vehicle, so you need to provide as much detail as possible
