1999 Toyota Camry struts

I was told by the corner mechanic that the noise that I hear when driving the car was do to the old struts needed to be replaced. It made a rattle sound which was definately coming from the front section of the car. So I had them replaced in the front, Get the car home it still rattles, car seems to drive better but I still get this rattle sound. I even check to see if the mechanic left a tool inside the front fender. Can not find the where it's coming from.

Did you ever hear of anything like this.
