407 marble sounds

Hello, I had seen the forum before for the air conditioner problem. I don't understand why this problem does now. Ball sound comes from the front, I also noticed today, I did not understand the wheel, I clicked like the sound of iron.

the ball of the forya is distributed, see which wheel comes from, or if you have a master, they will make the gothur, if your car has abs, it has to be an abs ball
