2. Rusty brake rotors: Rust on the brake rotors can also cause a squeaking sound when the brakes are applied. This is because the rust can cause the brake pads to vibrate, which in turn creates the squeaking sound.
3. Loose or worn-out suspension components: Worn-out or loose suspension components, such as ball joints or tie rods, can also cause a squeaking sound when the car is in motion, including when backing up.
4. Faulty power steering system: If your car has a power steering system, a faulty component in this system can also cause a squeaking sound when the car is in motion, especially when turning or backing up.
5. Worn-out CV joints: Constant velocity (CV) joints are responsible for transmitting power from the transmission to the wheels. When CV joints become worn out, they can cause a clicking or squeaking sound when the car is in motion, especially when turning or backing up.
