I have the same problem, i have the griggs kit, which is the same as yours, but the parts you circled are not my problem.
The cone and perch should not move, I dont think that is your problem.
Ive been struggling with a noise on my left front for months. I finally got the passenger side quiet, but im getting the same answers from everyone (check the strut bolt, spacers, washers.. bla bla. Its not that, and at a point my spring was actually hitting the inside of the strut tower opening. BINGO SOLVED! RIGHT?! nope. Still making noise. I searched elsewhere and found this answer was common:
Check the bushings on the control arm, and secure balljoints and swaybar links. Did that. Maybe a bushing is bad? Im going to change the balljoint and bushing on the left side. But if youre getting it on both sides, id check that the struts are not blown. I had 2 blown struts in the front and they were tapping like metal, sounded like the strut was loose, when it wasnt. Changed them out for konis, sound went away, but the left side was still giving me ****.
Ill let you know what happens with mine, but its the biggest PITA. If I were you, id double check that EVERYTHING is tight. I doubt its the spring perch. My kit is identical to yours and it is tight. I think you can rule that out. keep me posted.
