The Overlooked Alignment Angles That Reveal Hidden Suspension Damage
In this Motor Age Tech Tip Short, Erik Screeden takes technicians beyond the basics of camber and caster to explore two powerful diagnostic tools: steering axis inclination (SAI) and the included angle alignment. He explains how these hidden angles reveal deeper suspension diagnostics, helping techs pinpoint bent suspension components and uncover hidden damage that isn’t immediately visible. By breaking down how camber, caster and SAI interact, whether on an IFS Chevy pickup or a late-model Honda Civic with a MacPherson strut alignment, Screeden shows how even slight deviations can guide you to the real source of stubborn alignment issues.
Watch the full Tech Tip Short to see how mastering these angles can save time, improve accuracy and boost your diagnostic confidence. For more information, please visit www.launchtechusa.com.
