Many have experienced such. Over cobblestone roads, but not over speed bumps.
Fix for me was changing the lower control arms.
Drop link did not cure my car's knocking.
It also made the car more "firm" in the lateral and back n forth movement.
My car, 01 base, 5 speed. Use it as daily drive. Most streets are in good condition so the knocking became pronounced at about 100K miles.
