GENERAL DESCRIPTION
The front suspension is the strut type independent suspension. The upper end of a strut is anchored to the vehi-
cle body by a strut support. The strut and strut support are isolated by a rubber mount. A strut bearing is also
installed a little lower to the rubber mount.
The lower end of the strut is connected to the upper end of a steering knuckle and lower end of knuckle is
attached to the stud of a ball joint which is incorporated in a unit with a suspension control arm. And connected
to this steering knuckle is the tie rod end.
Thus, movement of the steering wheel is transmitted to the tie rod end and then to the knuckle, eventually caus-
ing the wheel-and-tire to move. In this operation, with the movement of the knuckle, the strut also rotates by
means of the strut bearing and lower ball joint.NOTE:
All front suspension fasteners are an important attaching part in that it could affect the perfor-
mance 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 nec-
essary. Do not use a replacement part of lesser quality or substitute design. Torque values must be
used as specified during reassembly to assure proper retention of this part.
Never attempt to heat, quench or straighten any front suspension part. Replace it with a new part or
damage to the part may result.
3F-2 WHEELS AND TIRES
GENERAL DESCRIPTION
TIRES
This vehicle is equipped with the following tire.
Tire size
: 165/70R14
The tire is of tubeless type. The tire is designed to operate satisfactorily with loads up to the full rated load
capacity when inflated to the recommended inflation pressures.
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 the following steel wheel.
Wheel size
: 14 x 4 1/2 J
REPLACEMENT TIRES
When replacement is necessary, the original equipment type tire should be used. Refer to the “Tire Placard”.
Replacement 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
clearance and tire or snow chain clearance to the body and chassis.
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 kilo pascal (kPa).
Tire pressures is usually printed in both kPa and psi on the “Tire
Placard”.
Metric tire gauges are available from tool suppliers.
The chart, shown the table, converts commonly used inflation
pressures from kPa to psi.
REPLACEMENT WHEELS
Wheels must be replaced if they are bent, dented, have excessive lateral or radial runout, air leak 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 figure below may cause objectional vibrations.
Replacement wheels must be equivalent to the original equipment wheels in load capacity, diameter, rim with
offset and mounting configuration. A wheel of improper size or type may affect wheel and bearing life, brake
cooling, speedometer/odometer calibration, vehicle ground clearance and tire clearance to body and chassis.WARNING:
Do not mix different types of tires on the same vehicle such as radial, bias and bias-belted tires except
in emergencies, because handling may be seriously affected and may result in loss of control.

HOW TO MEASURE WHEEL RUNOUT
To measure the wheel runout, it is necessary to use an 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 (1) and radial runout
(2) at both inside and outside of the rim flange. With the dial indi-
cator 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
“a” : 0.90 mm (0.035 in.)
Radial runout limit
“b” : 0.70 mm (0.028 in.)
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
DIAGNOSIS
DIAGNOSIS TABLE
Refer to Section 3.
BALANCING WHEELS
There are two types of wheel and tire balance : static and
dynamic. Static balance, as shown in left figure, is the equal distri-
bution of weight around the wheel. Wheels that are statically
unbalanced cause a bouncing action called tramp. This condition
will eventually cause uneven tire wear.
1. Heavy spot wheel tramp [A] : Before correction
2. Balance weights addition point [B] : Corrective weights
3. C/L of spindle

TIRE
MOUNTING AND DISMOUNTING
Use a tire changing machine to mount or dismount tires. Follow equipment manufacturer’s instructions. Do not
use hand tools or tire irons alone to change tires as they may damage tire beads or wheel rim.
Rim bead seats should be cleaned with a wire brush or coarse steel wool to remove lubricants, old rubber and
light rust. Before mounting or dismounting a tire, bead area should be well lubricated with approved tire lubri-
cant.
After mounting, inflate to specified pressure shown on tire placard so that beads are completely seated.
Install valve core and inflate to proper pressure.
REPAIR
There are many different materials and techniques on the market to repair tires. As not all of these work on all
types of tires, tire manufacturers have published detailed instructions on how and when to repair tires. These
instructions can be obtained from each tire manufacturer.WARNING:
Do not stand over tire when inflating. Bead may break when bead snaps over rim’s safety hump and
cause serious personal injury.
Do not exceed specified pressure when inflating. If specified pressure will not seat beads, deflate, re-
lubricate and reinflate.
Over inflation may cause bead to break and cause serious personal injury.
