Lift the front of the vehicle and support on jack stands as
per SAFETY section. Confirm the alignment of the front
springs. See “Front Spring Replacement” on page E - 8.
Rotate each wheel and scribe a chalk line around the
circumference of the tire at the center of the tread pat-
tern. Lower vehicle and, with tires in the straight ahead
position, roll it forward approximately five feet in order to
allow the tires to take their normal running position.
Measure the distance between the chalk lines at both
the front and rear of the tires (Ref Fig. 5). The measure-
ment taken at the front of the tires should be 0" - 1/8”
(0 - 3 mm) less than the rear.

To hold threaded tube while loosening jam nut, use a wrench
on the center, flat section of tube.
The tie rod has different threads on each end. The end

the flat area on the threaded tube has left hand threads (clock-
wise to loosen) while the end
without
the flat has conventional
right hand threads (counter-clockwise to loosen).
To adjust wheel alignment, loosen tie rod jam nuts (1)
and turn tie rod (2) until correct alignment is achieved.
Tighten jam nuts to 36 - 40 ft. lbs. (49 - 54 Nm) torque.
