Car sounds that signal impending repairs include squealing or grinding from the brakes and squealing from under the hood. Additional sounds may include sputtering or rattling from under the car.
When a squealing noise comes from the area of the front tires upon depressing the brake pedal, it indicates that the brake pads are wearing and need replacement. Grinding from the front tires typically indicates damaged brake pads, calipers or rotors that no longer work properly. Grinding may also signify damaged wheel bearings and joints.
Sputtering or rumbling from under the car is likely a leaking exhaust manifold or muffler. Rattling from under the car may indicate a loose or damaged exhaust clamp or other component that needs tightening or replacement.
