Well i finally found time to track the creaking down and Elmer is right it was in the sway bar!
I replicated the noise by supporting the unibody (off the ground) and putting a jack under the drivers side rear lower shock mount. I then jacked the drivers side of the rear end up and down and got the creaking to appear. I tracked it by feel (while jacking up and down)to the sway bar and lower control arm.
I then loosened the rear sway bar bolts and jacked up and down. Guess what know more noise!!!! But before i loosened them, I used a torque wrench to measure the torque upon loosening. It measured 110-120 foot pounds! My manual calls for 73 foot pound. I retightened all 4 sway bar bolts to 60 foot pound and the noise is still gone. I have put 50 miles on it since and it is quiet.
My guess is somehow the tighter they are the more tension (stiffness) it puts on the sway bar?
It looks like when my rear lower lca's were replaced by the recall (at the dealer) the tech just buzzed them down without torqueing them properly. Victim of the flat rate tech?
I choose to try and leave the sway bar on since my wife an children use the vehicle as a daily. I will keep everybody posted, but i believe it is solved. And thanks goes to Elmer! mike
