Default 2007 4.6 GT Grinding/creaking noise in rear when driving

I've almost given up hope trying to figure out what the problem is. I've replaced the shocks about two months ago, replaced the rear brakes and rotors, got the differential serviced (it was leaking from the pinion seal. I can't replicate the noise by simply bouncing the rear end up and down. I only hear the noise when coming to a stop and when accelerating from a stop and it is the most awful noise I've ever heard. I've jacked the car up at the rear and spun the wheels by hand and didn't hear the noise. There wasn't any play either. My only guess is the bushings on the rear sway bar but I don't really hear any noise when hitting bumps in the road. I've attached a link to a video where you can hear the awful noise.

Replaced my rear LCAs, all the sounds went away. There is a common noise
they make when coming to a stop that sounds like it's brake related, it wasn't. I
replaced the rear LCAs, that went away. There was a tiny squeak after, replaced
the panhard rod, that went away...

No Audio on the work PC but, LCA as mentioned or the UCA. There's only one of those and the bushing tends to get pulled in all directions because of it.
