3. Struts or Shocks: Worn-out struts or shocks can also cause a clunking noise, particularly when going over bumps or rough roads.

It is important to identify the source of the noise as soon as possible to prevent further damage to your vehicle. If the issue is not something you can fix yourself, it's best to take it to a trusted mechanic for diagnosis and repair.
