So I just purchased a beautiful Acadia AT4 and I’m quite happy. However… my roof rack cross bars produce A LOT of wind noise at anything over 50mph. Leaves me wondering if they were installed in the wrong direction. Anyone have similar issues? I plan on leaving them on year round because I like the extra off-road look it gives to the vehicle. But the noise is loud. Even with music blasting I can still hear the whistling hum loudly. Suggestions?
