1. Ensure that the tires are facing straight ahead.
2. Measure the center-to-center distance (at axle
height) at the front and rear of the steering tires
(Figure 49).
Note:
The measurement must be within 0 ± 3
mm (0 ± 0.12 inch) at the front of the tire then at
the rear of the tire. Rotate the tire 90° and check
the measurement.
