A knocking noise when going over bumpy roads can be caused by several factors, including worn-out suspension components like shock absorbers, struts, or bushings. Loose or damaged parts, such as sway bar links or control arms, can also contribute to the noise. Additionally, issues with the wheel bearings or even loose bolts in the undercarriage may result in knocking sounds. It's advisable to have a professional inspect the vehicle to identify and resolve the issue.
