Diagnostic Steps

1
Examine the ball joints for any visible signs of wear, such as cracks or tears in the rubber boots.
2
With the vehicle securely lifted, grasp the wheel at the 12 and 6 o'clock positions and attempt to wiggle it. Any excessive movement indicates worn ball joints.
3
While the vehicle is stationary, turn the steering wheel back and forth and listen for any unusual noises from the suspension area.
