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.

RADIAL TIRE LEAD
“Lead” is the deviation of the vehicle from a straight path on a level rod even with no pressure on the steering
wheel.
Lead is usually caused by:
Incorrect alignment.
Uneven brake adjustment.
Tire construction.
The way in which a tire is built can produce lead in a vehicle. An example of this is placement of the belt. Off
center belts on radial tires can cause the tire to develop a side force while rolling straight down the road. If one
side of the tire has a little larger diameter than the other, the tire will tend to roll to one side. This will develop a
side force which can produce vehicle lead.
The procedure in above figure (Lead Diagnosis) should be used to make sure that front alignment is not mis-
taken for tire lead.
Part of the lead diagnosis procedure is different from the proper tire rotation pattern currently in the owner
and service manuals. If a medium to high mileage tire is moved to the other side of the vehicle, be sure to
check that ride roughness has not developed
Rear tires will not cause lead.
VIBRATION DIAGNOSIS
Wheel unbalance causes most of the highway speed vibration problems. If a vibration remains after dynamic
balancing, its possible causes are as follows.
Tire runout.
Wheel runout.
Tire stiffness variation.
Measuring tire and/or wheel free runout will uncover only part of the problem. All three causes, known as loaded
radial runout, must be checked by using a Tire Problem Detector (TPD). If TPD is not available, alternative
method of substituting known-good tire and wheel assemblies on the problem vehicle can be used, although it
takes a longer time.
[A] : Tire out of round 1. Smooth road
[B] : Tire stiffness variation 2. Suspension movement (loaded runout)
[C] : Rim bent or out of round

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.

STEERING WHEEL AND COLUMN 3C-7
INSTALLATION
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.

NOTE:
All wheel fasteners are important attaching parts in that they could affect the performance of vital
parts and systems, and/or could result in major repair expense. They must be replaced with one of the
same part number or with an equivalent part if replacement becomes necessary. Do not use a replace-
ment part of lesser quality or substitute design. Torque values must be used as specified during reas-
sembly to assure proper retention of all parts.
There is to be no welding as it may result in extensive damage and weakening of the metal.
