Has anyone had a suspension squeak in the back that sounds like it's coming from the top of the strut? I've done a lot of looking and listening, and I'm guessing the bushing is worn or something. It's not any of the classic squeaks, like the sway bar or e-brake line, it's definitely a loud squawk from the strut tower (it's really loud with the seatbacks down). I don't want to remove the strut to fix it if I don't have to...
