Front Runner Rack whistling

I know this isn't the most technical question in nature, but I figured I'd reach out to the hive mind.

After installing the full length rack I am experiencing an extremely loud whistling sound between 25-50 miles mph. The noise isnt a rattle or a creaking, but more like air over and open bottle. The sounds is so loud that not even the tdi can mask it. It is also located above the drivers side window which make is worse

My only thoughts is that maybe there is some tension on the metal components on the rack and while driving, the air resistance is creating some sort of resonance kind of like a guitar string.

I have to think this is specific to my truck because I'm not sure FR would sell any racks if this was consistent across all installations.

Whats the best course of action? Loosen all bolts on the rack and retighten?

Throw a ratchet strap through your window openings and around the rack to determine if its resonance or wind noise.

I'll give that a try.

The fairing had a noticeable affect on the whoosing and the vibrating of the slats.

No luck with repositioning the rack and make sure there was no unnecessary tension on rack.
