Narrative:

During climb out, we observed a loud bang accompanied by a noticeable shudder in the cockpit. All indications and observations by cabin crew and deadhead cockpit crew member normal. No other noises/events until maneuvering towards final approach in st louis, when several smaller clunks accompanied by vibrations felt during the approach/landing phase. Upon gate arrival, I asked the ground crew to check the condition of the forward cargo pallets. The pallet loader inspected and remarked that the forward bin, loaded, was not properly locked in place and was moving around. No noticeable center of gravity problems during the flight, although that was a concern.
