Front Caster Adjustment

NOTE:
- All caster specifications are given with the vehicle frame level (zero angle).
- To make caster or camber adjustments the frame bracket knockouts must be removed.

1. Position the vehicle on a smooth level surface.
2. If needed, correct the "by" dimension to the correct specification.
3. Measure the frame angle, using a bubble protractor or inclinometer. The frame angle is the tilt (in degrees) of the frame from the level position.
4. Note the frame angle as being "up in the rear" or "down in the rear."
5. Determine the caster angle from the alignment equipment.
6. Refer to the image to determine the actual (corrected) caster reading. The following rules must be used for correcting the caster.
a. A "down in rear" frame angle must be subtracted from a positive caster reading.
b. An "up in rear" frame angle must be added to a positive caster reading.
c. A "down in rear" frame angle must be added to a negative caster reading.
d. An "up in rear" frame angle must be subtracted from a negative caster reading.
7. If the caster angle is wrong, remove the frame bracket knockouts.
8. Reset the caster angle by turning the cam bolts. Refer to "Specifications" in the image.
