I noticed that when I drive high speeds on the highway I’m hearing this flapping noise and I finally figured out that it’s the rear wing. It’s loose. Even if you go up and just grab hold of it you can move it a good more than an inch up and down. It wasn’t like that when I bought the car. So is there a way to tighten it or does it have to be replaced or Can it be glued down?
I took ours off one time. It was involved: you needed to removal panels partially on the inside of the hatch, and the interior end panels were tricky somehow. Ours wasn't that loose, it was more of a look-see in my case.
I did this too as I thought it was making a knocking sound, but turned out to be the tailgate hatch which I sorted myself.
