LCA bushings are a possibility.
If somebody put 12" sway bar end links on it they can bang on the LCA's, along with that the plastic stops on the bar can move allowing it to go back and forth excessively.
Could be the spring insulators on the struts, could be you were sold the incorrect struts (especially if they were complete assemblies).
See the link in my sig for diagnosing suspension noises.

The SS has a different strut from the LS/LT, if you got them saying "fits all" they are wrong. If you got complete struts, including the springs you probably got LT/LS struts, since nobody has been able to locate those for the SS.
The Lower Control Arm bushings are difficult to see, but can be checked with a crow bar.
You can look at the Lower Control Arms, if you see a mark on them near the sway bar end links, that is the bang.
You can look at the sway bar, just inside the bushings there is supposed to be a plastic collar/stop.
You can measure the sway bar end links, the correct ones will be approx. 10 inches center to center. Most parts books list the WRONG 12 inch part.
Have you checked the sway bar bushings? They can "look" good, but have play. Check with crow bar.

And since it is an SS; somebody may have replaced the LCA already with the WRONG ones. The parts books ALL list the one with the too small ball joints. get a micrometer and measure the diameter of the ball joint studs; they should measure 20.5 MM. Or look at them, if they are black they are wrong, they should be cast aluminum.
