(1) Scribe a line around the center of each front
tire by holding a chalk against the tire tread
while rotating the wheel.
(2) Measure distance (A and B) at front and
rear of wheels as shown and compare the
measurements (A) should be 0 to 1/8 in. (0
to 3.2 mm) shorter than (B). If the
difference between (A) and (B) is not within
this range, adjust tie rod as detailed in steps
3 thru 5.
(3) Loosen capscrews (1) and nuts (4) securing
left and right tie rod ends (2).
(4) Adjust tie rod length and thus front wheel
toe-in by turning tie rod (3) clockwise or
counterclockwise. Adjust until toe-in is
within range detailed in step 2.
Be sure tie rod is sufficiently
screwed into both tie rod ends to
provide effective clamping when
capscrews (1) are tightened.

and nuts (4) to 175 ft lb (235 Nm) when
