CASTER
1. Measure frame angle at "B", Fig. 1.
2. Check caster on alignment machine.
3. Using frame angle measurement and measured caster angle, determine actual (corrected) caster angle as follows:
a. Subtract a "down in rear frame angle from a positive caster angle reading, Fig. 2 (A).
b. Add an "up in rear frame angle to a positive caster angle reading, Fig. 2 (B).
c. Add a "down in rear frame angle to a negative caster angle reading, Fig. 2 (C).
d. Subtract an "up in rear frame angle from a negative caster angle reading, Fig. 2 (D).
4. Measure dimension "A Fig. 1.
5. Using dimension "A, refer to Figs. 3 and 4 and find the recommended caster angle.
6. The frame corrected angle should correspond to the recommended angle on the chart within plus or minus 1/4 degrees. Make necessary changes to bring caster angle within limits.

CAMBER
1. Determine camber angle using suitable equipment.
2. Add or subtract shims from both front and rear bolts to adjust camber as required.
