LOUD SQUEEK from right rear.....

Hello everyone. I have a 2000 W208 with 185K mikes, it's lowered with H&R springs with Maya 19" Wheels. Lately I'm hearing a loud squeek come from the righr rear. My Buddy who is a Tech for MBZ checked it out and couldn't find the problem. He went as far as removing the shock and putting the car back down and bouncing the car up and down and the squeek is still there. Has anybody else had this problem?? Please let me know as this sound is driving me NUTS!!!
Its possible that because the sound happens when bouncing that possible it is shocks or springs? shocks wear out.
