Subscribed I am going on the same hunt as well.
Removed the skid playe found a broken catch nut, replaced with an auto zone replacement that's comes as one unit.
Replaced sway bar end links no dice, I saw the springs that are attached to the brake lines that
@Blkshp18 mentioned but that's a different tone that I think OP is talking about.
@rstiehler were you able to crack this one? I am looking at replacing the front brake pads tomorrow.
Here is YT video of another person that had the same tone as what I am hearing but end links that diagnosed his noise hasn't fixed mine.
Thanks and hopefully this will crack the rattle noise.
