New computerized wheel alignments at Seymour
John Barnhart mounts a wheel sensor before initiating the alignment process. The wheel sensor transmits information directly to the computer to determine the angle of the tire. Wheel alignments are corrected with precision computer adjustments. Barnhart is a certified auto mechanic at the Auto Skills Development Center, and hails from Beaver Falls, Pa.
