If you have started to notice a clunking sound when driving over bumps, accelerating or stopping, a failing ball joint could be to blame.

The ball joints in your car are made so that the steering knuckle can be securely bolted to the control arm, yet still be free to move based on your inputs from the steering wheel. Over time though, the ball joints will wear out giving you an overall sloppy feeling suspension that makes all sorts of annoying noises.

The only remedy is to replace the failing ball joints with brand new ones.
