Clunking over speed bumps etc

After 1500 miles I went over a speed bump, a bit too aggressively I admit, and to my shock I heard rattling/clunking coming from some undefined place. I took it in to my Cadillac dealer and they replaced the sway bar links. After a couple of weeks I noticed the same noise again.
Now they’re replacing the entire front sway bar assembly.
Has anyone had a similar experience?
