4. MEASURING SYSTEMS (WITHOUT
SMALL DAMAGE)
S Whenever possible, make judgements and conclusions
based on measurement. Measure the wheel align-
ment(see pages 2–2, 2–3) so as to prevent any future
trouble like unsymmetrical wear of the tires or catchingof the steering wheel.
S If there are any deviations, use a tram tracking gauge
and measure parts of the body.(Below Fig. 5–1)
S If there is any twisting to the body, measure using a
frame centering gauge.(Below Fig. 5–2)
S When measuring body dimensions, use a universal tram
gauge.(Below Fig. 5–3)
