A vehicle becomes unpredictable when cornering due to what likely cause?

When a vehicle becomes unpredictable while cornering, worn track bushings can significantly contribute to this issue. Track bushings are designed to maintain proper alignment and control of the suspension components. If these bushings are worn or damaged, they can allow for excessive play in the suspension, leading to a lack of stability when cornering. This instability can manifest as wandering or a feeling that the vehicle is not responding accurately to steering inputs, making the vehicle feel unpredictable.

The other options may have effects on handling but do not directly address cornering behavior in the same way. For instance, worn shock bushings can lead to reduced damping performance but primarily affect ride quality rather than predictability in steering. Similarly, weak front or rear springs can impact suspension height and load distribution but won't create the same direct instability as worn track bushings do during cornering. Hence, the condition of the track bushings is critical for maintaining predictable handling dynamics.
