Crank pully is equipped with harmonic damper and if the damper has failed, it would result in the outer pulley ring slipping on its axis and when this occurs, it would result in abnormal noises and the alternator would not be providing sufficient charge as it is turning at a speed lower than required. The A/C might not feel as cold and steering effort could be harder.
When engine is running, check the crank pully for wavy movements.
