(6) and pitman arm ball. If excessive play is
observed, remove cotter pin (1) and tighten plug (3)
until it bottoms against ball, then back off until cotter
pin (1) can be installed install and secure cotter pin.
Note position of pitman arm relative to steering gear to
determine if adjustment of drag link is necessary, i.e.,
whether to increase or decrease length of drag link.
When drag link is correctly adjusted the pitman arm
should be at right angles to the steering gear axis (A)
when the wheels are straight ahead.
Remove cotter pin (2), plug (4) and loosen dust shield (8). Remove link end (9) from axle linkage ball
Loosen nut (11) and turn link end (9) clockwise or counterclockwise (full turns) to adjust length of drag

Three full turns changes the length 1/4 in. (6.4 mm).
