A whine or howl from the front axle, a clunk when drive load changes, or vibration can mean the gears or pins are worn. Before you replace the carrier, rule out low gear lube, worn axle shaft bearings and tire trouble, since each can produce similar noise; a shop can run any test that needs the vehicle raised.
