3E-2 WHEELS AND TIRES
DIAGNOSIS
• Hard cornering • Incorrect wheel alignment
• Heavy acceleration from a stop • Under infration • Tire unevenly worn • Lack of rotation • Over inflation
Fig. 3E-2
IRREGULAR AND PREMATURE WEAR
(Fig. 3E-2)
Irregular and/or premature wear has many causes.
Some of them are incorrect inflation pressures, lack of
tire rotation, poor driving habits or improper wheel
alignment. Incorrect inflation
is common cause of tire
premature wear.
NOTE:
Due to their design, radial tires tend to wear faster in
the
shoulder area, particularly on the front tires. This
makes
regular rotation especially necessary. After
rotation, be sure to check wheel nut torque, and set tire
pressures.
TIRE ROTATION
Tire rotation is recommended to equalize wear for
longer tire life (Fig. 3E-3).
Acceptable rotation patterns
Fig. 3E-3
Spare tire
If the following conditions are noted, rotate the tires:
• Front tire wear is different from rear.
• Uneven wear exists across the tread of any tire.
• Left and right front tire wear is unequal.
•
Left and right rear tire wear is unequal.
Check wheel alignment if the following conditions are
noted:
• Left and right front tire wear is unequal.
•
Wear is uneven across the tread of any front tire.
• Front tire treads have a scuffed appearance with
"feather" edges on one side of the tread ribs or
blocks.
TREAD WEAR INDICATORS (fig. 3E-4)
The original equipment tires have built-in tread wear
indicators to show when tires need replacement.
These indicators may appear as wide bands. When the
indicators appear in
two or more grooves at three
locations, tire replacement is recommended.
Fig. 3E-4
Tread wear

•

INFLATION OF TIRES
Tire pressure, in cold condition (after vehicle has setfor
three hours or more, and driven less than one mile),
should
be checked monthly or before any extended
trip. Tire pressure increases
approximately 15% when
the tires become hot during driving. Tire pressure
specification is shown on the
label located on the left
door lock pillar (Fig. 3E-5).
Fig.
3E-5
NOTE:
Check the tire pressure whenever irregular wear is
found. Tire
inflation greatly affects tire wear. If the
alignment check does not reveal any alignment
problems,
check the condition of the shock absorbers
and
wheel/tire balance.
WHEELS AND TIRES 3E-3
DIAGNOSIS LIST
If the following conditions are noted, rotation is
required.
1. Front tire wear is different from rear.
2. Uneven wear exists across the tread of any tire.
3. Left and right front tire wear is unequal.
4. Left and right rear tire wear is unequal.
If
the following conditions are noted, check the wheel
alignment.
1. Left and right front tire wear is unequal.
2. Uneven wear exists across the tread of any tire.
3. Front tire treads have scuffed appearance with
"feather" edges on one side of tread ribs or
blocks.
4. There is cupping, flat spotting etc.
Higher than recommended pressure can cause:
1. Hard ride.
2. Poor steering stability.
3. Rapid and uneven wear at center of the tread.
Lower than recommended pressure can cause:
1. Tire squeal on turns.
2. Hard steering.
3. Rapid and uneven wear on the edges of the tread.
4. Tire rim bruises and rupture.
5. Tire cord breakage.
6. High tire temperatures.
7. Reduced handling.
8. Reduced fuel economy.
Unequal pressure on same axle can cause:
1. Uneven braking
2. Steering lead.
3. Reduced handling.
4. Swerve on acceleration

W WARNING
TO AVOID DEPLOYMENT WHEN TROUBLE­
SHOOTING
THE SRS SYSTEM, DO NOT USE
ELECTRICAL TEST EQUIPMENT, SUCH AS
BATTERY-POWERED OR A/C-POWERED VOLT­
METER, OHMMETER, ETC., OR ANY TYPE OF
ELECTRICAL EQUIPMENT OTHER THAN SPE­
CIFIED IN THIS MANUAL. DO NOT USE A NON­
POWERED
PROBE-TYPE TESTER.
INSTRUCTION IN THIS MANUAL MUST BE
FOLLOWED CAREFULLY, OTHERWISE PER­
SONAL INJURY MAY RESULT.
This steering
wheel and column repair section covers
the Supplemental Restraint System (SRS) steering
column. The following repair procedures are specific
to SRS Components. When servicing a vehicle
equipped with Supplemental Restraint System, pay
close attention to all WARNINGS and CAUTIONS.
For detailed explanation about SRS, refer to Section
9J "SUPPLEMENTAL
RESTRAINT SYSTEM (SRS)" of
this manual.
The steering column has three important features in
addition to the steering function:
1. The column is energy absorbing, designed to
compress in a front-end collision to minimize the
possibility of injury to the driver of the vehicle.
2. The ignition switch and lock are mounted con­
veniently on the column.
3. With the column mounted lock, the ignition and
steering operation can be
locked to prevent theft
of the vehicle.
The column may be disassembled and reassembled.
To insure the energy absorbing action, it is important
that the specified screws, bolts and nuts be used only
as designated and that they are tightened to the
specified torque.
When the column is removed from the vehicle, a
sharp
blow on the end of steering shaft or shift lever,
leaning
on the column assembly, or dropping the
assembly could shear or loosen the fasteners that
maintain column rigidity.

SPECIAL SERVICE PRECAUTIONS
\f CAUTION:
Safe
handling of Inflator modules requires fol­
lowing the procedures described below for both
live and deployed modules.
\f WARNING
SAFETY PRECAUTIONS MUST BE FOLLOWED
WHEN HANDLING A DEPLOYED INFLATOR
MODULE (AIR
BAG). AFTER DEPLOYMENT, THE
INFLATOR MODULE (AIR BAG) SURFACE MAY
CONTAIN A SMALL AMOUNT OF SODIUM
HYDROXIDE,
A BY-PRODUCT OF THE DEPLOY­
MENT REACTION, THAT IS IRRITATING TO THE
SKIN AND EYES. MOST OF THE POWDER ON
THE INFLATOR MODULE (AIR BAG) IS HARM­
LESS. AS A PRECAUTION, WEAR GLOVES AND
SAFETY GLASSES WHEN HANDLING A DE­
PLOYED INFLATOR MODULE (AIR BAG), AND
WASH YOUR HANDS WITH MILD SOAP AND
WATER AFTERWARDS.
WHEN CARRYING A
LIVE INFLATOR MODULE
(AIR
BAG), MAKE SURE THE BAG AND TRIM
COVER ARE POINTED AWAY FROM YOU.
NEVER CARRY AN INFLATOR MODULE (AIR
BAG) BY THE WIRES OR CONNECTOR ON THE
UNDERSIDE OF MODULE. IN THE CASE OF AN
ACCIDENTAL DEPLOYMENT,
THE BAG WILL
THEN DEPLOY WITH MINIMAL CHANCE OF
INJURY. WHEN PLACING A LIVE INFLATOR
MODULE (AIR
BAG) ON A BENCH OR OTHER
SURFACE, ALWAYS FACE THE BAG AND TRIM
COVER UP, AWAY FROM THE SURFACE.
NEVER
REST A STEERING COLUMN AS­
SEMBLY ON
THE STEERING WHEEL WITH THE
INFLATOR MODULE (AIR BAG) FACE DOWN
AND COLUMN VERTICAL. THIS IS NECESSARY
SO THAT A FREE SPACE IS PROVIDED TO AL­
LOWTHE INFLATOR MODULE (AIR BAG) TO EX­
PAND
IN THE UNLIKELY EVENT OF ACCI­
DENTAL DEPLOYMENT.
OTHERWISE, PERSO­
NAL INJURY COULD RESULT.
For detailed explanation
about SRS, refer to Section
9J "SUPPLEMENTAL

\f' CAUTION:
Once the steering column is removed from the
vehicle, the
column is extremely susceptible to
damage. Dropping the column assembly on its
end
could collapse the steering shaft or loosen
the
slide block which maintains column rigidity.
Leaning on the column assembly could cause the
jacket
to bend or deform. Any of the above
damage could
impair the column's collapsible
design. If it is necessary to remove the steering
wheel, use
only the specified steering wheel
puller.
Under no conditions should the end of the
shaft be hammered upon,
as hammering could
loosen
slide block which maintains column
rigidity.
