95 Lumina suspension question

I have a 95 Lumina it started making a loud banging noise in the rear but only when going over a bump, replaced the rear struts and put new absorbers on. This did not fix the problem does anyone have any ideas on what it could be? Also, on the front end I can hear a rattling noise that sounds like its coming from behind the tire could that be the cv joints? Thanks

I have the same kind of rattling noise behind my front left tire, cant figure out what it is yet, is sounds flimsy like its a piece of the body work rattling but I have checked and thats not the problem.
