2007 squeaky front end suspension..help!
 

I bought a used 07 corvette 70k miles. Drove for a week in some rain and now i hear this squeak. Its coming from front end. I read alot on the forum and tried the following:

-spray control arms with white lithium
-unbolted and lubricated sway arm bushings
-unbolted leaf spring bracket and lubricated bracket
-lifted end of leaf spring and lubricated connection at control arm

STill the noise persists. You can push down on front end and hear it loudly. I havr a stethescope and hear it most on the leaf spring and the sway bar...what else can i try or did I not lubricate right spots on those parts?

Open to any suggestions. Thought may is bad shocks but im not convinced yet.
