Narrative:

Normal takeoff after nose strut servicing before departure in tpa. Both nose gear doors checked and latched by mechanic and supervisor while first officer and I watched. Logbook properly signed off. After gear was retracted, the noise from the nose area was very loud, buzzing vibration felt through floor. We stayed in the traffic pattern, lowered the gear and the noise stopped. We made a low pass so the tower and the waiting emergency equipment could check for damage before landing. Normal landing was made and I taxied to gate. Nose gear latch had vibrated loose, was reset by mechanic. Logbook signed off and normal flight to mia was made. Good cockpit resource management and checklist work.
