ABSTRACT:
A method of measuring a vehicular frame to determine alignment, where measurements provided in the manufacturer's specifications are known. The method consists of the following steps. Firstly, establishing at least one reference point spaced from a vehicular frame. Secondly, triangulating the vehicular frame by measuring the angle from the reference point to one or more coordinate points provided in the manufacturer's specifications. One side of the triangle containing the reference points is a reference line of a known length. Thirdly, using the length of the reference line and the angular measurement from the reference points as a basis for trigonometric calculation.
