Flapping sound from drivers side front fender?

[heavy hitter]

When driving on the freeway i get a flapping sound coming from what sounds like the drivers side front fender of my 01 qx4. It sounds like a seatbelt or something whipping around. Ive looked around and cant find anything that seems obviously loose. Anyone else encounter anything like this?

Could it be your fender liner, or the tire itself?

It doesnt seem to be. Ive checked both and nothing seems to be loose. No missing retainer clips or screws in the fender well

With the wheel, it might not manifest as looseness, but rather a defect in the tire itself.
Try rotating the wheel to a different position and you'll be able to see if the problem follows or not
