Some Chrysler 300 owners report experiencing a clunking noise that occurs periodically at various speeds, which may be linked to several potential issues. These owners note that the noise could be related to worn or damaged CV joints, particularly noticeable at higher speeds and over larger bumps. Additionally, loose or worn suspension and steering joints can produce various clacking and knocking sounds, especially when the vehicle's weight is on the wheels. Some owners have identified damaged bushings in the front suspension, including sway bar bushings, as a source of clunking noises when traversing bumps. Issues with sway bar end links, particularly worn or cracked components, may also contribute to the rattling sounds. Furthermore, problems with wheel components—such as unbalanced or misaligned wheels, tire damage, bent rims, bad wheel bearings, or loose lug nuts—can lead to vibrations and shaking at high speeds. It is advised that owners address these issues through thorough inspections and necessary replacements to resolve the clunking noise effectively.
