VEHICLE HEIGHT SPECIFICATION (3MZ-FE SPORT)Front (A - B) 120 mm (4.72 in.) Rear(D-C) 48 mm (1.89 in.) Measuring points:
A: Ground clearance of front wheel center
B: Ground clearance of lower suspension arm No. 2 set bolt center
C: Ground clearance of strut rod set bolt center
D: Ground clearance of rear wheel center
NOTE: Before inspecting the wheel alignment, adjust the vehicle height to the specified value.HINT:
Bounce the vehicle at the corners up and down to stabilize the suspension and inspect the vehicle height.
- INSPECT TOE-IN
Toe-in:
If the toe-in is not within the specified value, adjust it at the rack ends.
- ADJUST TOE-IN
- Remove the rack boot set clips.
- Loosen the tie rod end lock nuts.
- 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 value.
- Make sure that the lengths of the right and left rack ends are the same.
- Torque the tie rod end lock nuts.
Torque: 74 N.m (755 kgf.cm, 55 ft.lbf)
- Place the boots on the seats and install the clips.
HINT:
Make sure that the boots are not twisted.
- Perform VSC system calibration. (See PRE-CHECK )
- INSPECT WHEEL ANGLE
- Turn the steering wheel fully left and right, and measure the turning angle.
Wheel turning angle:

If the right and left inside wheel angles differ from the specified value, check the right and left rack end lengths.
- INSPECT CAMBER, CASTER AND STEERING AXIS INCLINATION
- Put the front wheel on the center of the alignment tester.
- Set the camber-caster-kingpin gauge at the center of the axle hub or drive shaft.

If the caster and steering axis inclination are not within the specified values, after the camber has been correctly adjusted, re-check the suspension parts for damaged and/or worn out parts.
- ADJUST CAMBER NOTE: After the camber has been adjusted, inspect the toe-in.
- Remove the front wheel.
- Remove the 2 nuts on the lower side of the shock absorber.
HINT:
When removing the nuts, keep the bolts from rotating.
- Clean the installation surfaces of the shock absorber and the steering knuckle.
- Temporarily install the 2 nuts.
- Adjust the camber by pushing or pulling the lower side of the shock absorber in the direction in which the camber adjustment is required.
- Tighten the nuts.
Torque: 210 N.m (2,141 kgf.cm, 155 ft.lbf)
NOTE: When installing nut, stop the bolt from rotating and torque them the nut. - Install the front wheel.
Torque: 103 N.m (1,050 kgf.cm, 76 ft.lbf)
- Check the camber.
HINT:
- Try to adjust the camber to the center of the specified value.
- Adjusting value for the set bolts is 6' to 30' (0.1 ° to 0.5°).
If the camber is not within the specified value, estimate how much additional camber adjustment will be required, and select the camber adjusting bolt.
NOTE: Tighten the adjusting bolt with a new nut. - Do the steps mentioned above again. At step (b), replace 1 or 2 selected bolts.
HINT:
When replacing the 2 bolts, replace 1 bolt for each time.
