What is a common indication of worn shock absorbers?

Worn shock absorbers are commonly indicated by excessive bouncing or poor vehicle handling over bumps. Shock absorbers play a crucial role in maintaining vehicle stability by dampening the effects of road irregularities. When they become worn, they lose their ability to effectively control the movement of the vehicle's suspension system, leading to increased oscillation and a bouncy ride, particularly noticeable when driving over potholes or bumps. This can result in a lack of control while steering, making the vehicle feel unstable or floaty.

The other options do not accurately reflect the symptoms of worn shock absorbers. For instance, increased fuel efficiency is generally not associated with the condition of shock absorbers; rather, it is affected by factors such as tire pressure and engine condition. Strange engine noises are typically related to engine issues or problems within the drivetrain, not the suspension system. Lastly, a smoother ride would indicate that the shock absorbers are functioning correctly, as they are designed to help absorb impacts and provide comfort while driving.
