Adjustment1) Loosen right and left tie-rod end lock nuts (1) first.
2) Rotate right and left tie-rods (2) by the same amount to align toe to specification. In this adjustment, the
lengths “A” of both right and left tie-rod should be
equal.
NOTE
Before rotating tie-rods (2), apply grease
between tie-rods and rack boots so that
boots won’t be twisted.

3) After adjustment, tighten lock nuts (1) to specified torque.
Tightening torque
Tie-rod end lock nut (a): 45 N·m (4.5 kgf-m, 32.5 lb-
ft)
NOTE
Make sure that rack boots are not twisted.

Camber and Caster Check
Check camber and caster by camber caster kingpin
gauge (1) and turning radius gauge (2).
If measured value is out of specified value, check
following items for damage, deformation and crack.
• Strut and component
• Suspension control arm and bush
• Suspension frame
• Wheel hub, steering knuckle or wheel bearing
• Vehicle body Front camber “a”
: 0
± 1°
Front caster “b”
: 5 °12’ ± 2°
NOTE
Front camber and caster are not adjustable.

Steering Angle Check and Adjustment
When tie-rod or tie-rod end was replaced, check toe and
then also steering angle with turning radius gauge.
If measured value is out of specified value, perform
inspection and adjustment of toe.
Steering angle
Inside: 33.8 ° ± 3 °
Outside: 29.8 ° (Reference)

• Inspect strut for oil leakage, damage or deformation.
• If defect is found, replace strut as an assembly unit, because it can not be disassembled.
• Inspect strut function re ferring to the following
procedures:
1) Check and adjust tire pressures as specified.
2) Bounce vehicle body up and down 3 or 4 times continuously by pushing front end of the vehicle side
body to check strut.
Also, note how many times vehicle body rebounds to
stop after force application.
3) Repeat the same procedure to the other strut to confirm that the both side struts equally respond.
If conditions of struts are in doubt, compare them with
known-good vehicle or strut.
• Inspect bearing for wear, abnormal noise or gripping. If defective, replace.
• Inspect coil spring seat for cracks or deformation.
If defective, replace.
• Inspect bump stopper for deterioration. If defective, replace.
• Inspect rebound stopper and strut mount for wear, cracks or deformation.
If defective, replace.

Front Wheel Hub, Disc, Nut and Bearing CheckS7RS0B2206008
• Inspect each wheel disc for dents, distortion and cracks.
A disc in badly damaged condition must be replaced.
• Check rust of installation face inside of wheel disc.
As rust affects adversely, remove it thoroughly.
• Check wheel nuts for tightness and, as necessary, retighten them to specification.
• Check wheel bolt press-fitted into wheel hub for wear, damage, poor thread condition, and looseness.
Replace defective bolt with a new one.
When bolt installation is found loose, replace both bolt
and wheel hub with new ones.
Tightening torque
Wheel nut: 85 N·m (8.5 kgf-m, 61.5 lb-ft)
