Not sure about second hand proecdures (unless you happen to have a receipt). I think it depends on the time of the year when its being sent in (one is like twice as long as the other).
Make sure that your servo isn't bound up with the ball cups connecting to the servo saver (I know ae cars have a habit of breaking the "fire wall" between the battery and the servo). Sometimes the battery pushes against the servo when you come to an abrupt stop.
