Ok, so this noise has been getting slightly louder for about 6 months and I've finally had it. I took off the trim in the rear of the car thinking it was just a loose wire or bolt/nut; couldn't find anything. I took all the stuff out of the trunk and couldn't find anything. I took a video while driving so you could hear the noise. It is a little louder than in the video as some of the road noise is drowning it out. Noise starts around 5 seconds

I read in a few previous posts that it could be something with the shocks. If that is the case can anyone confirm the noise? Also, what needs to be tightened?

Also, I don't know how to embed the video if someone wants to help with that to make it easy. Thanks!
