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.

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”

WARNING!
When handling rear shock absorber (1) in
which high-pressure gas is sealed, make
sure to observe the following precautions.
• Don’t disassemble it.
• Don’t put it into the fire.
• Don’t store it where it gets hot.
• Before disposing it, be sure to drill a hole (approximately 3 mm (0.12 in.) diameter)
(2) in it where indicated by arrow in the
figure and let gas and oil out.
Be sure to wear eye shield since the gas
itself is harmless but the absorber drill
hole debris maybe blown out.

Metric Lug Nuts and Wheel Studs
All models use metric lug nuts and wheel studs.
Metric lug nuts and wheel studs size
M12 x 1.25
If broken stud or nut are found, be sure to replace both
stud and nut with new one.
Irregular and/or Premature Wear DescriptionS7RS0B2401003
Irregular and premature wear has many causes. Some
of them are as follows: incorrect inflation pressures, lack
of tire rotation, driving habits, improper alignment.
If the following conditions are noted, tire rotation is
necessary:
• Front tire wear is different from rear’s.
• Uneven wear exists across tread of any tires.
• Both sides of front tire wears are not even.
• Both sides of rear tire wears are not even.
• There is cupping, flat spotting, etc.
A wheel alignment check is necessary if following
conditions are noted:
• Both sides of front tire wears are not even.
• Wear is uneven across the tread of any front tire.
• Front tire treads have scuffed appearance with “feather” edges on one side of tread ribs or blocks.
Wear Indicators DescriptionS7RS0B2401004
Original equipment tires have built-in tread wear
indicators (1) to show when they need replacement.
These indicators (1) will app ear as 12 mm (0.47 in) wide
bands when the tire tread depth becomes 1.6 mm (0.063
in).
When the indicators (1) appear in 3 or more grooves at 6
locations, tire replacement is recommended.

Radial Tire Waddle DescriptionS7RS0B2401005
Waddle is side to side movement at the front and/or rear
of the vehicle. It is caused by the steel belt not being
straight within the tire. It is most noticeable at a low
speed, 8 to 48 kph (5 to 30 mph).
It is possible to locate the f aulty tire by road testing the
vehicle. If it is on the rear , the rear end of the vehicle
shakes from side to side or “waddles”. To the driver in
the seat, it feels as though someone is pushing on the
side of vehicle.
If the faulty tire is on the front, waddling is more visual.
The front sheet metal appears to be moving back and
forth and the driver feels as though he is at the pivot
point in vehicle.
Waddle can be quickly diagnosed by using Tire Problem
Detector (TPD) and following the equipment
manufacture’s recommendations.
If TPD is not available, an alternative method of
substituting known-good tire / wheel assemblies can be
used as follows, although it takes a longer time. 1) Ride vehicle to determine whether the front or rear
waddles.
2) Install tires and wheels that are known to be good (on similar vehicle) in place of those on waddling end
of vehicle. If waddling end cannot be identified,
substitute rear ones.
3) Road test again. If improvement is noted, reinstall originals one at a time till w addle causal tire is found.
If no improvement is noted, install known-good tires
in place of all four. Then reinstall originals in the
same manner.
