问：这引起了轰动的声音。

你好呀。这是一个很好的问题；但是，我们需要更多信息，以便您对引起这种咆哮声的原因有一个准确的想法。If the roaring sound is coming during acceleration, it could be a worn out center gear (on the rear or 4WD front axle), or if it’s during braking, it could be the rotor that is warped that is causing the sound when the brakes are applied. The best way to minimize the guess work is to contact one of our professional mechanics so they can complete a汽车噪音的检查。
