STEERING WHEEL
STEERING WHEEL PLAY CHECK
Check steering wheel for looseness or rattle by trying to move it in
its shaft direction and lateral direction.
If found defective, repair or replace.
Check steering wheel for play, holding car in straight forward condi-
tion on the ground and with engine stopped.
Steering wheel play ªaº: 0 ± 30 mm (0 ± 1.2 in.)
If steering wheel play is not within specification, inspect as follows
and replace if found defective.

Tie-rod end ball stud for wear

Lower ball joint for wear

Steering shaft joint for wear

Steering pinion or rack gear for wear or breakage

Each part for looseness
STEERING FORCE CHECK
1) Place vehicle on level road and set steering wheel at straight-
ahead position.
2) Check that tire inflation pressure is as specified. (Refer to tire
placard.)
3) Start engine and keep it running till power steering fluid is
warmed to 50 to 60C (122 to 140F).
4) With engine idling, measure steering force by pulling spring ba-
lancer hooked on steering wheel in tangential direction.
Steering force: Less than 50 N (5.0 kg, 11.0 lb)
POWER STEERING FLUID
POWER STEERING FLUID LEVEL CHECK
With engine stopped, check fluid level indicated on P / S fluid reser-
voir, which should be between ªMAXº and ªMINº marks. If it is lower
than ªMINº mark, fill fluid up to ªMAXº mark.
NOTE:

Be sure to use an specified power steering fluid.

Fluid level should be checked when fluid is cool.

CAUTION:
Removal of the steering wheel allows the contact coil to turn
freely but do not turn the contact coil (on the combination
switch) more than allowable number of turns (about two and
a half turns from the center position clockwise or counter-
clockwise respectively), or coil will break.
REMOVAL
1) Remove driver air bag (inflator) module from steering wheel re-
ferring to ªDRIVER AIR BAG (INFLATOR) MODULEº earlier in
this section.
2) Remove steering shaft nut.
3) Make alignment marks on steering wheel and shaft for a guide
during reinstallation.
4) Remove steering wheel with special tool.
Special Tool
(A): 09944-36011
CAUTION:
Do not hammer the end of the shaft. Hammering it will
loosen the plastic shear pins which maintain the column
length and impair the collapsible design of the column.
CENTERING CONTACT COIL
1) Check that vehicle's wheels (front tires) are set at straight-ahead
position.
2) Check that ignition switch is at ªLOCKº position.
3) Turn contact coil counterclockwise slowly with a light force till
contact coil will not turn any further.
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.
4) From the position where contact coil became unable to turn any
further (it stopped), turn it back clockwise about two and a half
rotations and align center mark with alignment mark.

TEMº under ªSERVICE PRECAUTIONSº in Section 10B.
3) Remove steering wheel and contact coil and combination switch
assembly, if necessary. Refer to ªSTEERING WHEELº and
ªCONTACT COIL AND COMBINATION SWITCH ASSEMBLYº
in this section.
Perform the following procedure if not removing steering wheel
and/or combination switch.
ii) Turn steering wheel so that vehicle's front tires are at straight-
ahead position.
ii) Turn ignition switch to ªLOCKº position and remove key.
4) Remove steering column hole cover.
5) Disconnect all connectors for the following parts.

6) Make alignment marks on shaft joint and shaft (column side) for
a guide during reinstallation.
7) After removing bolt on column side of shaft joint and loosening
bolt on its lower shaft assembly side, move shaft joint to lower

WHEELS AND TIRES
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 replacement part
of lesser quality or substitute design. Torque values must be used as specified during reassembly to as-
sure proper retention of all parts.
There is to be no welding as it may result in extensive damage and weakening of the metal.
CONTENTS
GENERAL DESCRIPTION
TIRES
This vehicle is equipped with following tire. P215 / 65 R16, 215 / 65 R16 or 235 / 60 R16
The tires are of tubeless type. The tires are designed to operate satisfactorily with loads up to the full rated load
capacity when inflated to the recommended inflation pressure.
Correct tire pressures and driving habits have an important influence on tire life. Heavy cornering, excessively rapid
acceleration, and unnecessary sharp braking increase tire wear.
WHEELS
Standard equipment wheels are following steel wheel. 16
6 1 / 2 J or 16
7JJ
REPLACEMENT TIRES
When replacement is necessary, the original equipment type tire should be used. Refer to the Tire Placard. Re-
placement tires should be of the same size, load range and construction as those originally on the vehicle. Use
of any other size or type tire may affect ride, handling, speedometer / odometer calibration, vehicle ground clear-
ance and tire or snow chain clearance to the body and chassis.
NOTE:
Do not mix different types of tires on the same vehicle such as radial, bias and bias-belted tires except in
emergencies, because vehicle handling may be seriously affected and may result in loss of control.
It is recommended that new tires be installed in pairs on the same axle. If necessary to replace only one tire, it
should be paired with the tire having the most tread, to equalize braking traction.

The metric term for tire inflation pressure is the kilopascal (kPa).
Tire pressures will usually be printed in both kPa and psi on the Tire
Placard. Metric tire gauges are available from tool suppliers. The
chart, left table, converts commonly used inflation pressures from
kPa to psi.kPakgf / cm2psi

WHEELS REPLACEMENT
Wheels must be replaced if they are bent, dented, have excessive
lateral or radial runout, leak air through welds, have elongated bolt
holes, if lug nuts won't stay tight, or if they are heavily rusted.
Wheels with greater runout than shown in left figure may cause ob-
jectional vibrations.
Wheels for replacement must be equivalent to the originally
equipped wheels in load capacity, diameter, rim width, off-set and
mounting configuration. A wheel of improper size or type may affect
wheel and bearing life, brake cooling, speedometer / odometer cal-
ibration, ground clearance to the body and chassis.
To measure the wheel runout, it is necessary to use accurate dial
indicator. The tire may be on or off the wheel. The wheel should be
installed to the wheel balancer of the like for proper measurement.
Take measurements of both lateral runout and radial runout at both
inside and outside of the rim flange. With dial indicator set in place
securely, turn the wheel one full revolution slowly and record every
reading of the indicator.
When the measured runout exceeds the specification and correc-
tion by the balancer adjustment is impossible, replace the wheel.
If the reading is affected by welding, paint or scratch, it should be
ignored.
Lateral runout limit ªaº: 1.20 mm (0.047 in.)
Radial runout limit ªbº: 1.20 mm (0.047 in.)
METRIC LUG NUTS AND WHEEL STUDS
All models use metric lug nuts and wheel studs (size M12 x 1.25).
