1. Position the vehicle on a smooth level surface.
2. If needed, correct the "Z" 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 illustration 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 illustration.
CAMBER ADJUSTMENT
Important
^
To make caster or camber adjustments remove the frame bracket knockouts.
1. Determine the camber from the alignment equipment.
2. If camber angle is wrong, remove the frame bracket knockouts.
3. Reset the camber angle by turning the cam bolts. Refer to specifications in the illustration.
Front Toe Adjustment
1. Determine toe-in from the alignment equipment.
2. Change length of both tie rod sleeves to effect a toe change.
3. Toe-in can be increased or decreased by changing the length of the tie rod ends. A threaded sleeve is provided for this purpose. When the tie rod
ends are mounted ahead of the steering knuckle they must be decreased in length in order to increase toe-in. When the tie rod ends are mounted
behind the steering knuckle they must be lengthened in order to increase toe-in.
