What does it indicate if your vehicle keeps bouncing during a suspension test?

1. worn shock absorbers

2. excessive weight in the vehicle

3. incorrect tyre pressure

4. engine issues

The correct answer is: worn shock absorbers

When a vehicle continues to bounce after being pressed down at the corners during a suspension test, it indicates worn shock absorbers. Shock absorbers are crucial components of a vehicle's suspension system; they help to stabilize the vehicle by controlling the movement of the springs and ensuring that the tires remain in contact with the road surface. If the shock absorbers are worn, they cannot effectively dampen the spring motion, leading to exaggerated bouncing after the vehicle is released. This bouncing suggests that the suspension system is not adequately absorbing shocks from the road, which can affect handling and overall safety when driving. While other factors like excessive weight, incorrect tyre pressure, or engine issues might influence vehicle performance, they do not directly cause persistent bouncing during a suspension test like worn shock absorbers do.
