Narrative

AFTER A NORMAL LNDG AND ROLLOUT ON RWY 4R; WE WERE TAXIING ON TXWY D; AND WHILE INITIATING A R TURN ONTO TXWY D1 THE ACFT BECAME UNRESPONSIVE TO TILLER INPUTS. THE ACFT WAS STOPPED; THEN THE TURN WAS RECOMMENCED AT A VERY SLOW RATE. LOUD NOISES AND VIBRATION CAME FROM THE NOSE GEAR; AND STEERING WAS POOR; SO; I AGAIN STOPPED ACFT; SET BRAKES; AND CALLED FOR A VISUAL GND INSPECTION. GND CTL QUERIED A PASSING ACFT; WHICH RPTED SMOKE FROM THE NOSE GEAR. WE REQUESTED FIRE EQUIP; STARTED APU; SHUT DOWN ENGS AND ALERTED FLT ATTENDANTS; AS A PRECAUTION. SHORTLY AFTER; ANOTHER ACFT ADVISED OUR NOSE GEAR WAS NOW AFIRE. WE ADVISED ATC WE WERE EVACUATING; ALERTED THE CABIN; AND PERFORMED APPROPRIATE CHKLIST.
