Front Wheel Alignment
1. Rotate steering wheel to center the pitman arm with
the vehicle to ensure correct front wheel alignment mea-
surement.
2. With the pitman arm centered, measure center to
center distance (at axle height) between the front
wheels at both front and rear of the wheels (Fig. 28). The
front and rear measurements should be equal with a tol-
erance of 0.120” (3 mm). Rotate tires and make a sec-
ond measurement.
3. If measurements determine that an adjustment is
needed, loosen jam nuts on front tie rod ends and rotate
tie rods equally to change wheel alignment. Torque jam
nuts to 45 to 55 ft−lb (61 to 74 N−m) after adjustment
is complete.
4. After alignment has been checked and/or adjusted,
check for component interference as steering wheel is
turned from lock to lock. If necessary, adjust tie rods
equally to center steering components and then re−
check front wheel alignment.
5. Make sure that all jam nuts are properly torqued.
