Abstract:
1. A method for determining an alignment of a pair of vehicle wheels, comprising the steps of: placing a beam projecting and receiving device at a position remote from, and at one side of, a pair of vehicle wheels; positioning a beam reflecting device against a first vehicle wheel of said pair of vehicle wheels; projecting a beam from said beam projecting and receiving device to said beam reflecting device, so that a first reflected beam is projected back to said beam projecting and receiving device; subsequently positioning said beam reflecting device against a second vehicle wheel of said pair of vehicle wheels with an angular relationship between said beam reflecting device and each of said first vehicle wheel and said second vehicle wheel being equal; projecting a beam from said beam projecting and receiving device to said beam reflecting device, so that a second reflected beam is projected back to said beam projecting and receiving device, while maintaining said beam projecting and receiving device at said position; determining an angle between said first reflected beam and said second reflected beam; and, determining the alignment of said first vehicle wheel and said second vehicle wheel of said pair of vehicle wheels based upon said angle between said first reflected beam and said second reflected beam and excluding a pre-calibration procedure.
