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.

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.
