Think about it shaunk...if it made the noise when you were in full lock, the belt would more than likey be running off your power steering pump.
In the 2.4 models, thats the main belt. It runs off the crank, turn the water pump, alternator and power steering. The second smaller belt runs the a/c.
In the 2.0l models, the main belt runs off the crank and controls the water and steering pump. The smaller second belt runs the alternator.
In 2.0l models with air, the crank runs the water and steering pump. Off that is a second belt that runs the a/c and off the a/c is a third belt which runs the alternator.
So....yeah, when you turn your car into full lock, i would assume its the belt running the power sterring pump. So figure it out for whichever model you have!
But you had already got it fixed, so this post was probably a waste of time. Might help someone in the future though!
