    Whining Noise when Accelerating – Inspection & Repair in Hamilton

    What causes a whining noise when accelerating?

    When your car starts to make strange noises, it is always a reason for concern. However, these noises can be difficult to diagnose without knowledge of various engine components. There are several things that can cause your car to make noise as it accelerates. These include the following:


    Failing alternator bearings:New alternator Hamilton NZ

    When your car is running, the alternator generates electricity to power accessories and keep the battery charged. The alternator has several bearings which allow the alternator’s rotor to spin freely. If these bearings begin to fail, you will notice a loud whining noise, which will increase when you accelerate or the car is under heavier load.

    If the whining noises eventually result in electrical issues such as your car struggling to start, the alternator is the most likely culprit.

    Transmission problems:

    Issues with your car’s transmission can lead to a loud whining noise when you accelerate or change gears. Common transmission issues include:

    • Old or low transmission fluid – Transmission fluid should be replaced every 30,000 to 60,000 km. If the fluid is not replaced for a long time or a leak develops, you may start to notice a whining or grinding noise. This noise is caused by friction between unlubricated transmission parts. If this goes on for too long, transmission damage is likely to occur.
    • Bad transmission bearings – Your car’s transmission system has several bearings that can become damaged over time and need replacement. Damaged bearings can cause a loud whining noise as you accelerate which will become worse over time.


    Power steering problems:

    Your power steering system helps you to turn your vehicle steering easily from side to side. If part of the power steering system is not working correctly, you may hear a loud whining or squealing / squeaking noise. This will often be accompanied by a tighter steering wheel.

    Common causes of a failing power steering system include:

    • A damaged power steering pump
    • Low power steering fluid
    • Leaking or damaged hoses
    • Damaged or loose power steering belt

    The drive belt is what drives various components such as the alternator and power steering system. If the drive belt becomes loose, it will produce a loud whining or squealing noise as you drive.

    Loose drive belts should be tightened as soon as possible. This is because loose drive belts are more prone to overheating, damage and snapping.
