I replaced the front shocks and that seemed to help but now on a business trip down to Chi-town we were bounced silly!

I know it's the back end because I've gone back there both with the car off and idling and it seems I can really get the car rocking pretty easily by just pushing on it with my hands, no jumping on the bumper required.

I know the SLS is working after taking ground-to-body measurements before and after starting the car.

So...bad nitrogen cells? Am I just bouncing up and down on the springs like another post seemed to indicate?
