18. Remove left hand spindle nut and washer and install jiffy
caster and camber gauge as shown in Figure 1801 so that level
bubble is between gauge lines when pointer is set at zero. 19. Turn the head of the jiffy gauge so that it is parallel to
the axle as shown in Figure 1802 with wheels still straight
ahead and adjust the pointer with the thumbscrew until the
level bubble is between the lines on the glass. The reading
taken on the lower scale is the camber of the left wheel. A
reading toward the wheel is positive and away from the wheel
is negative camber; the correct camber is 1° to 1½º positive. If
camber is insufficient or reversed, check spindle pin inclina-
tion as follows:
20. Turn the head of the jiffy gauge parallel to the wheel as
shown in Figure 1803 and turn wheels to left until pointer on
left turning angle plate points to 25°.
21. Set pointer on zero and turn gauge on spindle until level.
22. Turn left wheel to right 25º and adjust level. The
pointer reading on the top scale is the king pin inclination. This
should be seven degrees.
NOTE: If the king pin inclination and the camber are off in
approximately the same amount (for example, camber ½°,
king pin inclination 6°), it is probably due to worn spindle pin
bushings. If camber is off and king pin inclination is correct,
the spindle is bent.
If spindle pin inclination and camber are both off an equal
amount and there is no play in spindle pin, the axle center is
bent. Camber should not be more than the specified 1½º;
