Front Wheel Alignment ConstructionS6RW0D2201002
Among factors for front wheel alignment, only toe setting
can be adjusted. Camber and caster are not adjustable.
Therefore, should camber or caster be out of
specification due to the damage caused by hazardous
road conditions or collision, whether the damage is in
body or in suspension should be determined and
damaged body should be repaired or damaged
suspension should be replaced.
Preliminary Checks Prior to Adjustment Front Wheel
Alignment
Steering and vibration complaints are not always the
result of improper wheel alignment. An additional item to
be checked is the possibility of tire lead due to worn or
improperly manufactured tires. “Lead” is the vehicle
deviation from a straight path on a level road without
hand pressure on the steering wheel. Refer to “Radial
Tire Lead / Pull Description in Section 2D” in order to
determine if the vehicle has a tire lead problem. Before
making any adjustment affecting wheel alignment, the
following checks and inspections should be made to
ensure correctness of alignment readings and alignment
adjustments:• Check all tires for proper inflation pressures and
approximately the same tread wear.
• Check for loose of ball joints. Check tie-rod ends; if
excessive looseness is noted, it must be corrected
before adjusting.
• Check for run-out of wheels and tires.
• Check vehicle trim heights; if it is out of limit and a
correction is needed, it must be done before adjusting
toe.
• Check for loose of suspension control arms.
• Check for loose or missing stabilizer bar attachments.
• Consideration must be given to excess loads, such as
tool boxes. If this excess load is normally carried in
vehicle, it should remain in vehicle during alignment
checks.
• Consider condition of equipment being used to check
alignment and follow manufacturer’s instructions.
• Regardless of equipment used to check alignment,
vehicle must be placed on a level surface.
NOTE
To prevent possible incorrect reading of toe,
camber or caster, vehicle front and rear end
must be moved up and down a few times
before inspection.

Front Wheel Alignment Inspection and
Adjustment
S6RW0D2206001
Toe Inspection and Adjustment
Preparation for toe inspection and adjustment.
• Place vehicle in unloaded state on level surface.
• Set steering wheel in straight state.
• Check that inflation pressure of each tire is adjusted
properly and wheel is free from deflection.
• Check that each suspension part is free from bend,
dent, wear or damage in any other form.
• Check that ground clearance at the right and left is
just about the same.Inspection
Measure toe with toe-in gauge (1).
Toe should be within following specifications.
If toe is out of the specification, adjust toe properly.

Adjustment
1) 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.

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 (1).
If steering angle is not correct, check whether right and
left tie-rods length “A” are equal.
NOTE
If tie-rod lengths were changed to adjust
steering angle, reinspect toe-in.

Steering angle
Inside: 36.0° ± 2°
Outside: 32.1° (Reference)
Reference Information
Side slip
When checked with side slip tester, side slip should
satisfy following specification.
Side slip
0 to IN 3.0 mm/m (0 to IN 0.118 in/3.3 ft)
If side slip is greatly difference, toe or front wheel
alignment may not be correct.

Front Strut Assembly Removal and InstallationS6RW0D2206003
CAUTION!
When rebound stopper and strut assembly
were removed, check strut support lower nut
for specified torque before installing strut
assembly.

Removal
1) Remove hood rear seal (1), and then remove cowl
top garnish (2) from vehicle.
NOTE
When servicing component parts of strut
assembly, beforehand loosen strut nut a little
before removing strut assembly. This will
make service work easier. Note that the nut
must not be removed at this point.

2) Hoist vehicle, allowing front suspension to hang free.
3) Remove wheel and disconnect stabilizer joint (1)
from strut bracket.
When loosening joint nut, hold stud with hexagon
wrench (2).4) Remove brake hose mounting bolt (1). Remove
brake hose (2) from bracket and wheel speed sensor
harness (3) from strut bracket as shown in figure.
5) Remove strut bracket bolts and nuts (4).
6) Remove strut nut (1), and remove rebound stopper
(2).
NOTE
Hold strut by hand so that it will not fall off.

7) Remove strut assembly.
