I have a 2006 Ford Fusion and since the temperature has been cold I have noticed a creaking sound when driving or turning. It doesn't seem to be caused by going over speed bumps, just minor undulations in the road or turning the wheel when not moving. I have isolated it to the front drivers side. I haven't had a chance to take a video of it yet, but I found a video on Youtube that demonstrates my problem. I can make the noise like the person in the video. And it only happens when it's cold outside, usually less than 40F.
