WHEELS AND TIRES 3F-3
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

band (3), adjust so that measurements become as indicated
below.
Drive shaft boot fixing position
“d” : 157.8 mm (6.21 in.) for left side
“e” : 192.9 mm (7.59 in.) foe right side
For Center Shaft and Center Bearing Support
Install center shaft by reversing removal procedure and noting fol-
lowing points
When installing bearing support circlip (1), make sure that if
fits in circlip groove in center bearing support (2) securely as
shown.
When installing left oil seal (1), use care so that oil seal in
proper direction as shown figure.
Be sure to apply grease to oil seal lip and bearing side space
indicated in figure.
“A” : Grease 99000-25010
After press-fit center shaft (2) from left oil seal side, install
circlip to groove of center shaft securely. CAUTION:
To prevent any problem caused by washing solution, do
not wash joint boots. Degreasing of those parts with
cloth is allowed.
CAUTION:
Bend each boot band against forward rotation (A).
Do not squeeze or distort boot when fastening it with
bands.
Distorted boot caused by squeezing air may reduce its
durability.

In such case, replace rubber seal.
ASSEMBLY
Assemble parts in reverse order of disassembly, observing the
following instructions.
“A” : Grease 99000-25010
Install piston seal to caliper referring to the following instruc-
tions.
a) Replace with a new one at every overhaul. Fit piston seal
(1) into groove in cylinder taking care not to twist it.
CAUTION:
Wash each part cleanly before installation in the same
fluid as the one used in master cylinder reservoir.
Never use other fluid or thinner.
Before installing piston and piston seal to cylinder,
apply fluid to them.
After reassembling brake lines, bleed air from them.
Install a new piston seal into groove in cylinder
securely making sure that it is not twisted.
Before installing caliper to carrier, install slide pin with
grease applied into caliper carrier hole and check for
its smooth movement in thrust direction.
