Knock, knock front end noise help!
 

I have a 2000 Intrepid. I had new strut put on the front. When driving slow, or when dry turning I get a knock noise from the front end. Looking at the strut springs, I see them turning when turning the steering wheel. Is this normal? The garage told me that it was and that it would stop after a while. The knock seems to be the springs as they rotate and jump into place.
