What is the first step a technician should take before adjusting alignment angles?

Before adjusting alignment angles, it is essential for a technician to visually inspect for worn or broken components. This step is critical because the condition of suspension and steering components directly impacts alignment settings. If components such as tie rods, ball joints, or control arms are worn or damaged, adjusting the alignment without addressing these issues could lead to further misalignment and uneven tire wear.

Inspecting for wear or damage ensures that any repairs or replacements are performed before making alignment adjustments, which can lead to more accurate results and improved vehicle handling. This thorough approach helps maintain safety and prolongs the life of the vehicle's tires and suspension system.
