I hear a noise


Things you can hear are wrong with your car…

  • Brakes make a rhythmic scraping noise at low speeds:
    As you step on the brake pedal to stop while moving at low speeds, you notice a rhythmic scraping noise. As the car slows, the frequency of the noise also slows. The noise doesn’t seem to be there when braking from high speeds. Sometimes the noise is more noticeable than at other times. The problem usually occurs suddenly.Possible causes:

    1. Your brake rotor is badly warped: Machine or replace brake rotors.
    2. Your front wheel bearings are badly out of adjustment: Adjust or replace wheel bearings as required.
    3. Your brake drums are badly out-of-round and need to be replaced: Machine or replace brake drums.

  • There is a scraping noise from the transmission:
    You notice a scraping, grating, or growling noise from the car whenever you start to move forward or in reverse. The noise seems to get worse the longer you drive the car. The noise is not there when you have the car in park or neutral. You don’t notice any other problems with the transmission.Possible causes:

    1. The transmission’s fluid level is low: Fill transmission fluid to proper level.
    2. The fluid in your transmission is contaminated: Flush transmission fluid and replace transmission filter.
    3. You have an internal problem in the transmission: Overhaul transmission.
    4. Your torque converter is bad: Replace torque converter.

  • Alternator makes a squealing noise:
    There is a squealing noise coming from the engine whenever you increase the speed of the engine. Upon inspection, you find the noise is coming from the alternator. The alternator seems to be working properly because the battery stays charged and the charging warning light doesn’t come on.Possible causes:

    1. Loose or damaged alternator drive belt: Tighten or replace alternator drive belt.
    2. The alternator’s internal bearings are worn: Replace alternator or bearings.

    Popping, Clicking and Knocking

     

  • Engine hesitates and a popping is heard from the engine:
    Whenever you step on the gas pedal, the car may hesitate and have general lack of power. The popping noise confirms that something is not right. The noise only happens when you press on the gas pedal. This problem may appear suddenly or get worse over time. You may notice the problem when the engine is hot or cold or when you are low on fuel.Possible causes:

    1. You may have a dirty air filter: Replace the air filter.
    2. The spark plugs may be dirty or worn: Clean and regap spark plugs. Replace spark plugs.
    3. The ignition wires may be bad: Replace ignition wires.
    4. There may be some other type of ignition problem: Check distributor cap or rotor. Ignition module may be bad.
    5. The engine may have mechanical problems: Check compression to determine engine condition.

  • Clicking from the front while turning a corner:
    Everything seems fine while you are driving your car except when you go around a corner, and then you hear a clicking noise from one side of the car. Pay attention to when the sound occurs, as it is very helpful when trying to identify what is causing the problem. Normally the problem begins gradually, but the noise may go unnoticed. As the problem gets worse, the noise gets louder.Possible causes:

    1. Brake pads/shoes are loose or broken: Replace the brake pads/shoes as required.
    2. Loose or bad front wheel bearings: Replace bad wheel bearings. Repack and retighten loose wheel bearings.
    3. Worn CV-joints (normally the outer joints): Replace CV-joints.
    4. Loose wheel covers (hub caps): Tighten or replace wheel covers.
    5. There is a large stone, a nail, or some other hard object caught in a tire: Remove foreign object(s) from tires.

  • Clicking noise during braking or turning:
    A distinct click that increases in speed as you increase the speed of the car. The clicking seems to occur whenever you apply the brakes and/or make a turn. If the clicking disappears when you release the brake, the cause is undoubtedly related to the brakes. This problem gradually becomes noticeable and can develop into a major problem.Possible causes:

    1. Loose or bad front wheel bearings: Replace bad wheel bearings. Repack and retighten loose wheel bearings.
    2. The brake pads are loose in their mounting: Tighten or replace brake pads as required.
    3. CV-joints are worn: Replace CV-joints.
    4. There is a hard object caught between the brake pads and the rotor: Remove foreign object(s) from brakes.
