- INSPECT TOE-IN
Toe-in: Hatchback
TOE-IN REFERENCEA+B C-D 0°09'+-0°13' (0.15° +- 0.22°) 1.5 +- 2.0 mm (0.06 +- 0.08 in.) Sedan
TOE-IN REFERENCEA+B C-D 0°12'+-0°06' (0.20°+-0.10°) 2.0 +- 2.0 mm (0.08 +- 0.08 in.) 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.
- ADJUST TOE-IN
- 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
- Remove the rack boot set clips.
- Loosen the tie rod end lock nuts.
- Adjust the rack ends if the difference in thread length between the right and left rack ends is not within the specified range.
- Extend the shorter rack end if the measured toe-in deviates toward the outer-side.
- Shorten the longer rack end if the measured toe-in deviates toward the inner-side.
- 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.
- Make sure that the lengths of the right and left rack ends are the same.
Toe-in
TOE-IN REFERENCEBody Type Toe-in Hatchback 1.5 +- 1.0 mm (0.06 +- 0.04 in.) Sedan 2.0 +- 1.0 mm (0.08 +- 0.04 in.) - Tighten the tie rod end lock nuts to the specified torque.
Torque: 75 N*m (760 kgf*cm, 55 ft.*lbf)
NOTE: 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. - Place the boots on the seats.
- Using pliers, install the clip.NOTE: Make sure that the boots are not twisted.
- Measure the thread lengths of the right and left rack ends.
- INSPECT WHEEL TURNING ANGLE
- Fully turn the steering wheel left and right, and measure the wheel turning angle.
Wheel turning angle
WHEEL TURNING ANGLE REFERENCEDestination Inside Wheel Outside Wheel (Reference) Except for Rough Road Package 40°57'+-2° (40.95° +- 2°) 35°17' (35.29°) Rough Road Package 41°22'+-2° (41.37°+-2°) 35°45' (35.75°) If the right and left inside wheel angles are not within the specified range, check the right and left rack end lengths.
- Fully turn the steering wheel left and right, and measure the wheel turning angle.
- INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION
- Put the front wheel on the center of the alignment tester.
- Remove the wheel cap.
- Set the camber-caster-steering axis inclination gauge at the center of the axle hub or drive shaft.
- Inspect the camber, caster and steering axis inclination.

- The tolerance for the difference between the left and right wheels is 30' (0.5°) or less for both the camber and caster.
- Remove the camber-caster-steering axis inclination gauge and attachment.
- Install the wheel cap.
If the caster and steering axis inclination are not within the specified values after the camber has been correctly adjusted, recheck the suspension parts for damage and wear.
- ADJUST CAMBER NOTE: Inspect the toe-in after the camber has been adjusted.
- Remove the front wheel.
- w/ ABS:
- Remove the bolt and separate the speed sensor and flexible hose.
- Remove the 2 nuts on the lower side of the shock absorber.
HINT:
Keep the bolt from rotating while loosening and removing the nuts.
- Clean the installation surfaces of the shock absorber and steering knuckle.
- Provisionally install the 2 nuts (Step a).
- Fully push or pull the axle hub in the direction of the required adjustment (Step b).
- Tighten the 2 nuts.
Torque: 164 N*m (1,672 kgf*cm, 121 ft.*lbf)
HINT:
Keep the bolt from rotating while loosening and removing the nuts.
- w/ ABS:
- Install the flexible hose and speed sensor with the bolt.
Torque: 29 N*m (300 kgf*cm, 22 ft.*lbf)
NOTE: Install the flexible hose and speed sensor without twisting them.
- Install the flexible hose and speed sensor with the bolt.
- Install the front wheel.
Torque: 103 N*m (1,050 kgf*cm, 76 ft.*lbf)
- Check the camber.
If the measured value is not within the specification, calculate the required adjustment amount using the formula below.
(Camber adjustment amount) = Center of specified range - Measured value
Check the combination of installed bolts. Select appropriate bolts from the table below to adjust the camber to within the specified range.
HINT:
Try to adjust the camber to the center of the specified range.
CAMBER SPECIFICATIONSMove axle toward (+) in step (B) Refer to Fig 14 (Move axle toward positive side) Move axle toward (-) in step (B) Refer to Fig 15 (Move axle toward negative side) - Table (1) (Move the axle toward the positive side).
- Table (2) (Move the axle toward the negative side).
The body and suspension may be damaged if the camber is not correctly adjusted in accordance with Fig 15 .
NOTE: Replace the nut with a new one when replacing the bolt. - Repeat the steps mentioned above. At step (A), replace 1 or 2 selected bolts.
HINT:
Replace one bolt at a time when replacing 2 bolts.
