Mercrusin

Hello I have a 2007 Mercury milan base, 2.3L with around 130,000 miles. I have had a horrible noise that is similar to a squeak or creak every time I ......A) turn the wheel or when I hit bumps or pretty much drive not in a smooth straight road. The noise seems to be dramatically worse when the weather is cold ( I live in ohio) and you can always hear it very prominent outside the car and inside. I had the front struts and top rubber boots replaced last year and that seemed to help temporarily but It is another year and the sound is just as bad. The mechanic said nothing else seemed wrong at the time and the stock struts were not even bad. I had read on this forum at one point or another about something needing to be aligned with some holes in the suspension but I'm not sure. Has anyone else had this problem or any help with this. It's to the point I don't enjoy the car because people stop and stare at it when I drive it, it's kind of embarrassing! Thanks for any help or input
