But if the slides were the problem it would only stop if I lift the seat up so that the 2 metal slides change their position. But its only necessary to lift the edge of the cushion (the leather wrapping to be exact) slightly up.

If look a little bit closer but nothing down there is loose, and its not a metal on metal squeak. it has a higher pitch. more like wet plastic or scratching over a blackboard.
