Alright y'all followup to my previous note. Finally got some time to poke around under there. And the noises were two fold. The front skid was loose, and just needed to be snugged up. The other was a little more insidious, and harder to diagnose. With one hand I was pulling down on the hoop to force the sound, and the other feeling around down there for tactile evidence of the noise, which worked. There is a thin piece of metal trim that runs directly below the stock grill, and was making contact with the two vertical supports on the bumper on either side.
I didnt have a ton of time to work on this, but I'll probably either trim or bend the piece as a permanent fix. In the meantime, I've slid a square of dense neoprene foam in between the contact points to prevent the contact.
Buttoned it all back up, and the squeaking and squawking is gone! Very stoked!
