This text investigates the mechanical principles and procedural standards required to perform accurate wheel alignment on automotive vehicles. E. M. Bacon provides a technical framework for understanding suspension geometry, tire wear patterns, and the impact of alignment settings on vehicle handling. The book serves as a reference for technicians to diagnose steering irregularities and implement corrective adjustments using standard shop equipment.

Technicians and automotive students frequently cite this work as a foundational reference for understanding the physics of wheel geometry. Experts note that while the technology described reflects traditional mechanical methods, the core principles remain relevant for manual alignment diagnostics.
