What causes a grinding noise going over bumps in a 2004 Jeep Grand Cherokee?

A grinding noise in a 2004 Jeep Grand Cherokee when going over bumps can be caused by several issues, including worn-out suspension components like shock absorbers or struts, damaged bushings, or failing ball joints. It may also stem from loose or damaged exhaust components that come into contact with the undercarriage. Additionally, issues with the drivetrain, such as worn CV joints, could contribute to the noise. A thorough inspection is recommended to accurately diagnose the problem.
