It is a fact that the ball joints for Jeep JK will fail sometime. Noise and moderate shaking of the vehicle may not be much of a problem at first but then it is always nice to attend to an issue at an initial stage. If the problems are left on their own, vehicle performance and handling can suffer later on. It can also lead to tire wear and malfunctioning wheel alignment. If a ball joint completely gives off, the suspension can break-off and vehicle control will be lost fully resulting in a mishap.
