Narrative:
Prior to gate departure; maintenance replaced a ram air temperature probe relay in the east&east compartment. After takeoff and gear retraction (gear up no lights); there was a very loud rumbling noise with an associated vibration coming from the nose gear area. The noise and vibration increased with an increase in speed. Aircraft was leveled at 5000 ft for troubleshooting. Gear was cycled one time but noise and vibration continued. Because of the uncertainty of the structural integrity of the nose gear area; and upon consultation with maintenance; the decision was made to declare an emergency and make an overweight landing at 144000 pounds. Uneventful landing ensued. Crash fire rescue equipment as well as maintenance inspected the nose gear area and found one of the forward nose gear access doors was down. Gear pin was installed and aircraft was taxied to gate.

Title: AN MD83 ON INITIAL CLB AT 1000 FT DECLARED AN EMER AND DIVERTED DUE TO NOSE GEAR NOISE AND VIBRATION. FOUND ONE NOSE GEAR ACCESS DOOR OPEN.
Narrative: PRIOR TO GATE DEP; MAINT REPLACED A RAM AIR TEMP PROBE RELAY IN THE E&E COMPARTMENT. AFTER TKOF AND GEAR RETRACTION (GEAR UP NO LIGHTS); THERE WAS A VERY LOUD RUMBLING NOISE WITH AN ASSOCIATED VIBRATION COMING FROM THE NOSE GEAR AREA. THE NOISE AND VIBRATION INCREASED WITH AN INCREASE IN SPD. ACFT WAS LEVELED AT 5000 FT FOR TROUBLESHOOTING. GEAR WAS CYCLED ONE TIME BUT NOISE AND VIBRATION CONTINUED. BECAUSE OF THE UNCERTAINTY OF THE STRUCTURAL INTEGRITY OF THE NOSE GEAR AREA; AND UPON CONSULTATION WITH MAINT; THE DECISION WAS MADE TO DECLARE AN EMER AND MAKE AN OVERWT LNDG AT 144000 LBS. UNEVENTFUL LNDG ENSUED. CFR AS WELL AS MAINT INSPECTED THE NOSE GEAR AREA AND FOUND ONE OF THE FORWARD NOSE GEAR ACCESS DOORS WAS DOWN. GEAR PIN WAS INSTALLED AND ACFT WAS TAXIED TO GATE.
