Valerie Cappello Denville, New Jersey - 2005 Dodge Caravan
Noise/exhaust? There's a humming metal-on-metal noise, from the front of the car. It happens only when she accelerate. She's pregnant and due in a month with 2nd child. Husband hears it selectively, thinks she's overreacting, and it's not worth worrying about. Probably the differential--gears worn out. If they don't fix it, noise will drive them crazy, and eventually gears will stiop working.
