clunk
Heavy impact sound
Clunk is a dull, heavy sound—the noise of metal hitting metal or something solid dropping: The car door shut with a clunk, I heard a clunk from the engine.
As a verb, to clunk is to make or move with such a sound: He clunked the wrench down on the workbench.
A clunker is an old, unreliable car prone to making such noises.
