I did read through all the threads on this, and I taped off with masking tape all seams of the windshield and all seams of the sunroof. I also slid back the roof rack cross member. Still. Howling wind noise at speeds around 40+ mph. I am at a loss for where this whistling can be coming from. The one thing I’ve noticed is if I tilt or slide the sunroof even slightly, the noise seems to go away. Albeit ill hear just the noise from the sunroof being open, but the whistle goes away. Does that explain anything to anyone? Any ideas? The truck is dead silent and smooth otherwise.
