3F-2 WHEELS AND TIRES
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).

ON-VEHICLE SERVICE
WHEEL
REMOVAL
1) Loosen wheel nuts by approximately 180
(half a rotation).
2) Hoist vehicle.
3) Remove wheel.
NOTE:
Never use heat to loosen tight wheel because application of
heat to wheel can shorten life of wheel and damage wheel
bearings.
INSTALLATION
Wheel nuts must be tightened in sequence and to proper torque to
avoid bending wheel or brake drum or disc as in figure.
NOTE:
Before installing wheels, remove any build-up of corrosion on
wheel mounting surface and brake drum or disc mounting sur-
face by scraping and wire brushing. Installing wheels without
good metal-to-metal contact at mounting surfaces can cause
wheel nuts to loosen, which can later allow wheel to come off
while vehicle is moving.

GENERAL DESCRIPTION
The drive shaft joint is a constant velocity joint (C.V. joint) which slides in the axial direction. The joint is composed
of an outer race, cage, inner race and balls. In the turning direction, the joint rotates in the same way as a ball bear-
ing. The balls lock rotation completely and transmit drive. In addition this vehicle is also characterized by a function
that the shaft can slide through the balls in the grooves of the outer race in the extension / contraction direction of
the drive shaft.

CAUTION:

To prevent any problem caused by washing solution, do
not wash joint boots. Degreasing of those parts with cloth
is allowed.

For M / T vehicle with H25 engine
To ensure full performance of joint as designed, be sure
to distinguish between two types of grease in repair set
and apply specified volume to respective joint. i.e. yellow
grease to wheel side joint and black one to differential
side.

Bend each boot band against forward rotation.

Do not squeeze or distort boot when fastening it with
bands.
Distorted boot caused by squeezing air may reduce its du-
rability.
1) Fully apply joint grease to wheel side joint.
Use joint grease in the tube included in spare part.
2) Fit wheel side boot on shaft.
Fill up inside of boot with joint grease of about 90 gram.
Before fixing boot band, insert screwdriver into boot on joint side
and allow air to enter boot so that air pressure in boot becomes
the same as atmospheric pressure.
3) Fixing boot band.
4) Install boot onto drive shaft till its small diameter side fits to shaft
groove and fix there with boot band.
5) Install cage to shaft.
CAUTION:
Install cage directing smaller outside diameter side to
shaft end.
