I sprayed some silicone on the bottom hats or the spring perch. After. I wish I had layed a little grease where the springs contact the mount points. You should check some bolts for tightness after someone does your work. My car is quiet as it should be now but i also got some disturbing noises and went after them. One of them was not enough grease when i Installed sway bars. So i greased them till snotty and no noise now. The attachment point at the front strut tower will clunk if loose etc. Just some thought as I hate to see a fellow member disappointed
