What condition should leaf springs be in for suspension inspection?

For a suspension inspection, the critical condition for leaf springs is that there should be no cracks on any leaf springs. Cracks can significantly compromise the structural integrity and function of the leaf springs, which are essential for supporting the vehicle's weight and maintaining proper alignment of the wheels. If cracks are present, it can lead to failure of the spring, resulting in suspension issues that can affect vehicle handling, safety, and performance.

While other factors such as rust, paint condition, and lubrication have their own importance in maintaining the overall health of the suspension system, the presence of cracks is a more immediate concern that indicates a serious problem requiring attention. Therefore, ensuring that leaf springs are free from cracks is vital for the safe operation of the vehicle.
