who hears a loud thud from their car after hitting big bumps now? I guess this problem comes from cars with stiffer springs with shocks(drop) because instead of the softer shocks absorbing the bump, it now goes into the body.

So what causes this noise? I never used to have when my car was newly dropped. Do some parts in the body get loose after awhile from taking the impacts or something? Guess you really shouldn't mess with a car cuz it all comes back to you.
