A common inspection procedure for leaf spring suspensions involves checking for cracks, missing leaves, and proper alignment. Leaf springs are crucial components of a vehicle's suspension system, providing support and stability. The integrity of these springs is essential for the safe operation of the vehicle, as they absorb shocks and help maintain a level ride height.

Cracks in the leaf spring can lead to failure during operation, which poses significant safety risks. Similarly, missing leaves can reduce the load-bearing capacity and compromise the suspension system's function. Proper alignment is critical as well; misalignment can cause uneven wear on other components and negatively affect handling characteristics.

While signs of rust can be considered during an inspection, they do not provide a comprehensive check of the suspension's health. Measuring shock absorber length is relevant to the overall suspension system but does not specifically pertain to leaf spring inspection. Checking brake fluid levels is unrelated to the leaf spring suspension and rather pertains to the braking system of the vehicle. Therefore, focusing on cracks, missing leaves, and alignment directly addresses the functional aspects that are vital to the safety and efficiency of leaf spring suspensions.
