Which defect can lead to suspension system failure?

The presence of cracked or broken spring hangers is a significant concern that can lead to suspension system failure. Spring hangers are critical components of the vehicle's suspension system, as they support the springs and help maintain the proper positioning of the axle. If these hangers are cracked or broken, they can compromise the integrity and stability of the entire suspension system. This can result in poor handling, increased wear on other suspension components, and ultimately create a hazardous driving situation due to diminished vehicle control.

While low oil levels, dirty air filters, and worn-out tires can lead to other mechanical issues or affect the performance of different systems in the vehicle, they do not directly compromise the suspension system in the same way that damaged spring hangers do. Understanding the importance of maintaining intact suspension components is crucial for safe vehicle operation and effective load management.
