DIAGNOSIS
GENERAL DIAGNOSIS
Since the problems in steering, suspension, wheels and tires involve several systems, they must all be consid-
ered when diagnosing a complaint. To avoid using the wrong symptom, always road test the vehicle first. Pro-
ceed with the following preliminary inspection and correct any defects which are found.
1) Inspect tires for proper pressure and uneven wear.
2) Raise vehicle on a hoist and inspect front and rear suspension and steering system for loose or damaged
parts.
3) Spin front wheels. Inspect for out-of-round tires, out-of-balance tires, bent rims, loosen and/or rough wheel
bearings.

TIRE DIAGNOSIS
IRREGULAR AND/OR PREMATURE WEAR
Irregular and premature wear has many causes. Some of them
are: incorrect inflation pressures, lack of tire rotation, driving hab-
its, improper alignment.
If the following conditions are noted, rotation is necessary:
Front tire wear is different from rear.
Uneven wear exists across the tread of any tire.
Front tire wear is unequal between the right and left.
Rear tire wear is unequal between the right and left.
There is cupping, flat spotting, etc.
A wheel alignment check is necessary if following conditions are
noted:
Front tire wear is unequal between the right and left.
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
Original equipment tires have built-in tread wear indicators (1) to
show when they need replacement.
These indicators (1) will appear 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 loca-
tions, tire replacement is recommended.NOTE:
*1: Right-to-left trim height (“H”) difference should be
within 15 mm (0.6 in.) with curb weight. (same with rear
side.)
“H”
[A] : Hard Cornering, under inflation or lack of tire rotation
[B] : Incorrect wheel alignment, tire construction not uniform or wheel heavy acceleration

RADIAL TIRE WADDLE
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 faulty 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 recommenda-
tions.
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 waddle causal tire is found. If no
improvement is noted, install known-good tires in place of all four. Then reinstall originals in the same man-
ner as above.
EQUIPMENT MANUFACTURE’S RECOMMENDATIONS
In flate tires to recommended pressure
Road test vehicle on level unrowned road in both directions
Switch front tires side to side and road test again
Lead corrected,
if roughness results, replace tiresLeads in same directionLeads reverses direction
Put tires back in original position
and check alignmentInstall a known-good tire on one front side
Lead remains install a known-good
tire in place of other front tire
Lead remains known-good tires are not goodLead corrected replace tire
Lead corrected replace tire

FRONT END ALIGNMENT 3A-3
DIAGNOSIS
DIAGNOSIS TABLE
For the details, refer to Section 3.
PRELIMINARY CHECKS PRIOR TO ADJUSTING FRONT ALIGNMENT
Steering and vibration complaints are not always the result of improper alignment. An additional item to be
checked is the possibility of tire lead due to worn or improperly manufactured tires. “Lead” is the deviation of the
vehicle from a straight path on a level road without hand pressure on the steering wheel. Procedure for deter-
mining the presence of a tire lead problem contains in SECTION 3. Before making any adjustment affecting toe
setting, the following checks and inspections should be made to ensure correctness of alignment readings and
alignment adjustments:
1) Check all tires for proper inflation pressures and approximately the same tread wear.
2) Check for loose of ball joints. Check tie rod ends; if excessive looseness is noted, it must be corrected
before adjusting.
3) Check for run-out of wheels and tires.
4) Check vehicle trim heights; if out of limits and a correction is to be made, it must be made before adjusting
toe.
5) Check for loose of suspension arms.
6) Check for loose or missing stabilizer bar attachments.
7) 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.
8) Consider condition of equipment being used to check alignment and follow manufacturer's instructions.
9) Regardless of equipment used to check alignment, vehicle must be on a level surface both fore and aft and
transversely.
TOE 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-in to specification. In this adjustment, right and left tie
rods (2) should become equal in length “A”.
3) After adjustment, tighten lock nuts (1) to specified torque.
Tightening torque
Tie rod end lock nuts (a) : 45 N·m (4.5 kg-m, 32.5 lb-ft) NOTE:
Before rotating tie rods (2), apply grease between tie
rods and rack boots so that boots won't be twisted.
NOTE:
Make sure that rack boots are not twisted.

1) Check that vehicle’s front tires are at straight-ahead position
and contact coil is centered. Refer to “CENTERING CON-
TACT COIL”.
2) Install steering wheel (1) to steering shaft with 2 lugs (2) on
contact coil fitted in two grooves (3) in the back of steering
wheel and also aligning marks (4) on steering wheel and
steering shaft.
3) Tighten steering shaft nut (1) to specified torque.
Tightening torque
Steering shaft nut (a) : 33 N·m (3.3 kg-m, 24.0 lb-ft)
4) Install driver air bag (inflator) module to steering wheel.
Refer to “DRIVER AIR BAG (INFLATOR) MODULE”.
CENTERING CONTACT COIL
1) Check that vehicle’s wheels (front tires) are set at straight-
ahead position.
2) Check that ignition switch is at “LOCK” position.
3) Turn contact coil counterclockwise slowly with a light force till
contact coil will not turn any further. CAUTION:
These two conditions are prerequisite for installation of
steering wheel. If steering wheel has been installed with-
out these conditions, contact coil will break when steer-
ing wheel is turned.
NOTE:
After installing the steering wheel, turn the steering
wheel about 1 full rotation so that the cancel cam pin fits
into the pin hole in the steering wheel and then check the
turn signal lever for proper function.
NOTE:
Contact coil can turn about 5 turns at maximum, that is, if
it is at the center position, can turn about two and a half
turns both clockwise and counterclockwise.
