Adding to what I wrote a few months ago, one of the elevators just won't stay in place. It pops up every time I close the sunroof door and that's about 6 months later! - Here is my first review: I bought it about 4 months ago. They were easy to install. But almost immediately they squeaked. You're talking so relentlessly loud now it's a shame to open the hatch. In the public. At first I thought the bushings were to blame, but no matter how much I lubricated them, the creaking stayed. I've been listening and it seems to me it's coming from the tube.
