got a squeak...can anybody find it?

[pocketAA]

It seems to be coming from the passenger side rear end or from the back of the car some where. I only hear it when I go over big bumps etc. The car does have the Random Tech cat back on it and it is a 99 rt/10. Any idea of where I should start looking? Could it be the cat back moving around? Something with the suspension?
Thanks!

I had a squeak on the passenger side going over bumps.

Removed the passenger side rocker panel, blew out the debris and reinstalled.

Squeak is history.
