HINT:

Only measure C-D when A+B can not be measured.If the toe-in is not within the specified value, adjust it at the rack ends.4.

ADJUST TOE-IN

(a)Measure the thread lengths of the right and left rack

ends.

Standard:

Difference in thread length of 1.5 mm (0.059 in.) or less

(b)Remove the rack boot set clips.(c)Loosen the tie rod end lock nuts.

(d)Adjust the rack ends if the difference in thread

length between the right and left rack ends is not within the specified range.

(1)Extend the shorter rack end if the measured

toe-in deviates toward the outer-side.

(2)Shorten the longer rack end if the measured

toe-in deviates toward the inner-side.

(e)Turn the right and left rack ends by an equal amount

to adjust the toe-in.HINT:

Try to adjust the toe-in to the center of the specified range.

(f)Make sure that the lengths of the right and left rack

ends are the same. Toe-in

(g)Tighten the tie rod end lock nuts to the specified

torque.

NOTICE:

Provisionally tighten the lock nut while holding

the hexagonal part of the steering rack end so

that the lock nut and the steering rack end do

not turn together. Hold the width across flat of

the tie rod end and tighten the lock nut.

(h)Place the boots on the seats.

(i)Using pliers, install the clip as shown in the

illustration.

NOTICE:

Make sure that the boots are not twisted.

5.INSPECT WHEEL TURNING ANGLE

(a)Fully turn the steering wheel left and right, and

measure the wheel turning angle.

Wheel turning angle

If the right and left inside wheel angles are not within

the specified range, check the right and left rack end

lengths.

6.INSPECT CAMBER, CASTER AND STEERING AXIS

INCLINATION

(a)Put the front wheel on the center of the alignment

tester.

(b)Remove the wheel cap.

(c)Set the camber-caster-steering axis inclination

gauge at the center of the axle hub or drive shaft.

(d)Inspect the camber, caster and steering axis

inclination.

Inspect the toe-in after the camber has been adjusted.

(a)Remove the front wheel.

(b)w/ ABS:

(1)Remove the bolt and separate the speed

sensor and flexible hose.
