The rear end on my cx9 seems low ...could this be the shock absorbers

Hello, Do you have air ride suspension or self leveling suspension? How tall are the... nevermind, I'm kidding. I don't think it was offered, but self leveling suspension can do that easily, and is normally adjustable to an extent. Also, the tailgate support struts (they make the pshhhhh noise as the tailgate is lifted) do this when they wear out. Can you raise the tailgate with your and if it seems all the way up?
