Your technician will inspect for worn or damaged parts that will prevent proper alignment.

He will measure current alignment angles by mounting the electronic sensors on all four wheels of your auto. Infrared beams will measure the position and angle of each wheel and determine exactly in which direction each wheel is pointing. A severely out of alignment auto will have all four wheels pointing in different directions. As the tech performs various tests, the complete set of measurements is sent to the aligner's computer console. The computer compares your car's measurements with the auto manufacturer's specifications in its database.

The aligner then provides the technician with the exact information he needs to adjust your car's alignment to match factory specifications.
