Which of the following are defects found in the suspension system?

The suspension system of a vehicle is crucial for maintaining stability, comfort, and control while driving. Options that reference missing or damaged parts, as well as leaking shock absorbers, directly relate to the suspension system's functionality. Specifically, missing or damaged components can impair the system's ability to absorb shocks from the road, leading to a rough ride and potential handling issues. Similarly, leaking shock absorbers indicate that the hydraulic fluid used to dampen movement is escaping, which compromises the shock absorbers' effectiveness in maintaining proper tire contact with the road, further affecting safety and performance.

While other options mention significant vehicle issues, they do not pertain specifically to the suspension system. Worn tires and broken leaves might influence ride quality but are not exclusive to the suspension system. Excessive rust and loose bolts refer more broadly to vehicle integrity and safety rather than targeting suspension-specific defects. Lastly, inadequate fuel levels and faulty lights involve different systems within the vehicle altogether, such as the fuel system and electrical components, which do not impact the suspension. Therefore, the reference to missing parts and leaking shock absorbers in the suspension is the correct identification of defects that can significantly affect vehicle operation and safety.
