03 Cobra lower control arms?

Has anyone had problems with a noisy front end? I took the cobra in to have Ford check out the my front end. I was in traffic one day and had to hit the brakes hard and heard a noise when the nose of the car dove down.
I took the car in and they had a TSB on it and replaced the lower control arms.(they had to order them) A little fyi for you all! She dosen't pull to the right anymore either.
