suspension issue

What is your question?

When i got the car it had a slight shake to it when driving. i drive 100 miles a day and the shake has increased quite a bit and there is a metal on metal smacking sound when i go over bumps. oddly the smaller the bump, the more noise i hear. ive checked everything short of pulling out the strut assembly and cannot find anything loose. the sound comes from the rear strut area mostly on the right, but the left still makes noise just not as much. if i take an off ramp at high speeds and hit a bump while turning it snaps the car and throws it slightly. any ideas would greatly be appreciated.
