During a pre-alignment inspection, the technician finds rust streaks on one rear left spring. What is the recommended action?

When observing rust streaks on a rear left spring during a pre-alignment inspection, inspecting the spring for cracks is the recommended action. Rust can indicate potential deterioration and weakening of the material, but the key issue is to assess the structural integrity of the spring.

The presence of rust might not automatically necessitate replacement, especially if the structure of the spring is sound. Inspecting for cracks helps ensure that the spring can still function effectively without compromising safety. If cracks are found, then further actions, including possibly replacing the spring, would be warranted. This approach helps in determining the best course of action that guarantees both safety and cost-effectiveness, allowing the technician to make an informed decision based on the condition of the spring.
