I hear a creaking sound when I turn the steering wheel. Could it be because it's cold?

May have teo replace the tie rod

It could be several problems but you can easily trouble shoot them. first ensure there has been a greese job done recently and it will help eliminate the ball joints and tie rod ends. the other culprit is the strut top. you may be able to trouble shoot this by spraying silicone/lube in around the top of the strut either from the top or bottom. you can do this with the ball joints and tie rod as long as you use a good lube(not wd40) check the boots for cracks (source for water ingestion). Hope this helps
