As with any suspension component, your control arm mounts can deteriorate over time or become damaged. Worn mounts cause vague, imprecise steering response, harsh ride, and noise, including squeaks and clunking. Replacing worn bushings and mounts is usually the first recommended step in refreshing a vehicles handling or ride characteristics. The control arm mounts secure control arms to the chassis. Mounts should be inspected as part of a regular maintenance schedule and replaced as needed when signs of wear or damage are detected.
