Steering System Noise Definitions: Clonk

Clonk is a structure-borne noise heard as a loose-sounding rattle or vibration coming from the steering column. Clonk is identified by driving and turning over cobble stones, rough roads or high frequency bumps, such as 1-2 inch tall tar strips or frost heaves. Clonk is a noise heard only while cornering over bumps. Clonk requires a tie-rod load impact. Clonk can sound identical to Column Knock, that also occurs when driving over cobble stones or rough road. Clonk may appear to emanate from a location closer to the floor than for column knock.
