It turned out to be the ends of the rods. They have a plastic bushing that covers the end and nests in the metal notch.
Had to pry it down and force silcone grease around it.
Good as new again.
....But Damn GM didn't cover it under my extended warranty and it cost me $30 bucks for 15 minutes work.
I know how to do it now so I won't be taking it back there again.
I tried before taking it in to spray silicone lube all around it but it didn't work.
Prying it down and greasing it was the only way to rid the creaking.
