Narrative:

On departure from boston; just after wheels up; a sliding noise was heard followed by a thump. Some vibration was noted in the yoke followed by the flight attendants calling the cockpit to inform us of the vibration in the tail. The vibration continued and appeared to be getting worse. The flight crew requested permission to return to boston to have the vibration inspected by maintenance. The approach and landing were uneventful. Boston crash fire rescue equipment followed the aircraft to the gate. One of the possibilities for the vibration was a bird strike; but no bird strike was found after inspecting the aircraft. The aircraft was taken OTS for further inspection. An emergency was not declared; however; it was handled as an emergency by ATC. Callback conversation with reporter revealed the following information: the reporter stated that the vibrations started after rotation; with noise and vibrations in the control column and tail. The vibrations were increasing and the decision was made to return to the field. Landing was uneventful but on taxi in; got #2 engine filter clog light. Maintenance pulled the main oil screen and found it full of metal. The screen was replaced and the engine would not rotate when a start was attempted. Airplane was removed from service and the engine replaced. Supplemental information from acn 674914: we heard a thump; followed by a brief moan coming from somewhere aft of the cockpit.
