3. Common Causes of Whistling Noises

3.1. Improper Installation

One of the primary causes of whistling noises from roof racks is improper installation. If the system is not correctly secured or components are misaligned, it can lead to gaps and spaces that alter the airflow pattern. Consequently, whistling sounds become more pronounced.

3.2. Inadequate Wind Deflectors

Wind deflectors, also known as fairing, play a crucial role in minimizing roof rack noises. These attachments redirect the airflow smoothly, reducing the chances of vibrations and noise generation. However, if your roof rack doesn’t come with a wind deflector or if the deflector is too small for your vehicle, it can contribute to whistling noises.
