A ball joint is the pivot between the suspension and the steering knuckle. It lets the wheel steer and travel over bumps while holding it in position. Clunking over bumps, loose or wandering steering, and uneven tire wear are signs this part may need replacing. Have the front end inspected to confirm the cause before you replace parts.
