Front Wheel Alignment ConstructionS7RS0B2201002
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 join
ts. 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 missin g 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 manufa cturer’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.

Repair Instructions
Front Wheel Alignment Inspection and
Adjustment
S7RS0B2206001
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 using toe-in gauge (1).
If toe is out of specified value, adjust it at the tie-rod. Front toe (total) “b”-“a”
: 0 + 1.0 / – 0.5 mm (0 + 0.0394 / – 0.0197 in.)

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)
