Narrative:

I taxied out from the north cargo ramp, den, when I heard a noise from the nose wheel. Got a clearance to taxi back to the north cargo ramp, L6 taxiway. The nose wheel came off. The plane was towed to a maintenance shop, where a mechanic concluded that the cause was the freezing of the wheel bearing.
