Clunking noise when I drive over bumps Inspection
Heavy metallic clunking or knocking noise when driving over speed bumps or rough roads? A bump clunking inspection pinpoints worn sway bar links, blown struts, bad ball joints, and deteriorated control arm bushings.The most common cause of a sharp, metallic clunk over small bumps is worn sway bar end links or deteriorated sway bar frame bushings: as the rubber bushings or internal ball-and-socket joints wear down, the stabilizer bar slams against its mounting hardware under chassis movement.
