help me diagnose suspension squeak....

i had replaced all my suspension components recently and am having a very loud pronounced squeaking noise come from the front and rear supspension

i replaced stock parts with koni yellows, uuc sway bars and bushings and subframe bushings... reused xdrive springs, i have the shocks on full soft currently

seems to be getting worse and worse and more pronounced

what could i be? it sounds very squeaky and springy and more pronounced over slow bumps like a speed bump it sounds horrible

is it the springs? a bushing? sway bar link? shock or spring mount? the install was done 100% and the parts and the car feel very solid except for this horrible squeak and sounds pretty much identical front to rear

here is a clip of the sound sorry for the poor camera work but you can hear the sound clearly at the 10 second mark sounds like a creaky old spring bed mattress

in the above video, the noise at 10-13 second mark is the squeak in question

sorry the vids aren't great but if you turn the volume up loud you will hear it
