Noise – Squealing Sounds
Description of Problem:
2. Once you have determined the belt that is the cause of your squeal, you will need to check it for tightness, and replace if it is worn. As mentioned above, common belts that squeal are the power steering belt if you hear the noise during turns, and the A/C belt if the noise is noticeable only when the A/C is on. Other belts to consider are the alternator belt if you hear the sound under load or acceleration, or if under idle it may be the timing belt.
3. If the noise is not coming from the belts, you will want to determine wheteher the sounds from the brake system are during stopping, or during travel. If you hear the squeal only when applying the brakes, this may be an annoyance more than a problem. If you depress the pedal lightly and hear a faint squale, you can likley obtain some anti-squeal brake paste to apply to the pads to minimize the noise. If you get the squeal when braking hard as well, you may need a different type pad or lining than what is currently installed. If you notice the noise while driving and it disappears when you step on the brakes, this is most likely caused by the sensors on your current pads rubbing and emitting the noise to notify you it is time to have your brake pads replaced.
