  1. anyone have this squek in the back new the mach 460 speakers? seems some other have it too, curious if anyone has figured out where its coming from?

  2. I to had squeak, rattle, groans in rear seat area. I found them all.

    1. remove spare tire and line tire well with carpet. Make sure tire does
    not touch metal sides or bottom.

    2. remove rear seat bottom and rear seat back and lower metal support
    frame. insulated lower metal support frame from were it hits trans
    tunnel on body. also insulated were lower metal frame support bar goes
    over threaded rod. make sure when you replace rear seat back its metal
    bar that goes over threaded rod over lower rear support bar does not
    touch each other. when installing nuts make sure they are insulated also.

    3. when re-instaling rear seat also insulate the metal frame (back of seats)
    from contact with the metal of the rear support frame of car body.

    hope this helps
