I sure am glad i found this thread--i just started noticing a creaking, metallic click sound coming from my front wheels. I can faintly hear it when i turn the steering wheel back and forth. It is not loud at all so I can't think it is a bad control arm or ball joint. I googled it and found a very interesting youtube video that aligned with my symptoms.
So, according to the video...it's the control arm ball joint nuts that are not tight enough. (sound is not coming from control arm, it's coming from ball joint).
