What generally happens when the bushings in a suspension system wear out?

When the bushings in a suspension system wear out, one of the most common effects is increased noise, vibration, and harshness (NVH). Bushings are designed to act as flexible mounts for various components of the suspension system, such as control arms and stabilizer bars. They serve to absorb shocks, provide cushioning, and allow for some movement between parts.

As these bushings degrade due to age, environmental conditions, or fatigue, they lose their ability to properly dampen vibrations and absorb impacts. This degradation can lead to a harsh ride experience, as more road noise and feel are transmitted to the vehicle's cabin. The loss of isolation can also result in the amplification of vibrations, which contributes to an uncomfortable driving experience.

In contrast to high NVH levels, options suggesting improved ride comfort, enhanced steering responsiveness, or decreased load capacity do not accurately reflect the consequences of worn bushings. Worn bushings generally lead to a decrease in ride quality and handling performance, making option A the correct choice.
