You turned the corner and your car made a loud noise like someone thew something at it But after that it made this noise and you parked it right away because you were afraid to drive it?

Sounds like something in the suspension system like maybe a shock or srut may be worn out or the rubber grommet (each has one on each end that the mounting bolt goes through) on one of them is gone or damaged. Or maybe something in the trunk turned over or slid around or maybe somebody left a wrench under the hood.Good luck.
