Higher than Recommended Pressure Can Cause:
1. Hard ride
2. Tire bruising or carcass damage
3. Rapid tread wear at center of tire
Unequal Pressure on Same Axle Can Cause:
1. Uneven braking
2. Steering lead
3. Reduced handling
4. Swerve on acceleration
Valve caps should be kept on valves to keep dust and
water out.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. High fuel consumption
MAINTENANCE AND MINOR ADJUSTMENTS
WHEEL AND TIRE
Wheel repairs that use welding, heating, or peening are not approved. All damaged wheels should be replaced.
STUDS
If a broken stud is found, see Section 3E (rear) or Section 3D (front) for Note and Replacement procedure.
MATCHED TIRES AND WHEELS
(For vehicle equipped with steel wheels)
Tires and wheels are matchmounted at the assembly plant.
This means that the radially stiffest part of the tire, or ªhigh spotº, is
matched to the smallest radius or ªlow spotº of the wheel.
This is done to provide the smoothest possible ride.
The ªhigh spotº of the tire is originally marked by paint dot on the
outboard sidewall. This paint dot will eventually wash off the tire.
The ªlow spotº of the wheel is originally marked by paint dot on the
wheel rim-flange. Properly assembled, the wheel rims' paint dot
should be aligned with the tires' paint dot as shown in left figure.
Whenever a tire is dismounted from its wheel, it should be re-
mounted so that the tire and wheel are matched. If the tire's paint
dot cannot be located, a line should be scribed on the tire and wheel
before dismounting to assure that it is remounted in the same posi-
tion.
INFLATION OF TIRES
The pressure recommended for any model is carefully calculated to give a satisfactory ride, stability, steering, tread
wear, tire life and resistance to bruises.
Tire pressure, with tires cold, (after vehicle has set for three hours or more, or driven less than one mile) should
be checked monthly or before any extended trip. Set to the specifications on the tire placard located on the side
of instrument panel.
It is normal for tire pressure increase when the tires become hot during driving. Do not bleed or reduce tire pressure
after driving. Bleeding reduces the ªCold Inflation Pressureº.

REMOVAL (RIGHT SIDE)
1) Hoist vehicle and remove wheel.
2) Drain differential gear oil.
3) Remove axle shaft drive flange.
4) Remove circlip and front spindle thrust washer.
5) Remove knuckle and wheel hub comp, refer to steps 5) to 7) and
9) to 14) of item COIL SPRING REMOVAL in Section 3D.
6) Remove drive shaft assembly.
To detach snap ring fitted on the spline of differential side joint
(inboard joint) from differential side gear, pull inboard joint by us-
ing a tire lever.
CAUTION:
To prevent breakage of boots (wheel side and differential
side), be careful not to bring them into contact with other
parts when removing drive shaft assembly.
7) Remove drive shaft thrust washer (to vehicle with G16 or J20 en-
gine) from drive shaft and remove drive shaft oil seal as shown
in figure.
CAUTION:
Be careful not to cause damage to drive shaft joint.

DISASSEMBLY
1) Remove boot band of differential side joint.
2) Slide boot toward the center of shaft and remove snap ring from
outer race, then take shaft out of outer race.
3) Remove circlip and then cage.
4) Remove inside and outside boots from shaft.
CAUTION:
Do not disassemble wheel side joint (outboard joint). If
any malcondition is found in joint, replace it as assem-
bly.
Do not disassemble ball joint of differential side joint.
If any malcondition is found in ball joint, replace differ-
ential side joint assembly.
INSPECTION
Check boots for breakage or deterioration. Replace them as nec-
essary.
Check circlip, snap ring and boot bands for breakage or deforma-
tion. Replace as necessary.
CLEANING
Wash disassembled parts (except boots) in degreaser. After
washing, dry parts completely by blowing air.
Clean boots with cloth. DO NOT wash boots in degreaser, such
as gasoline or kerosene, etc.
Washing in degreaser causes deterioration of boot.

INSTALLATION
Install drive shaft assembly by reversing removal procedure and
noting following points.
Clean front drive shaft oil seal and then apply lithium grease to oil
seal and DOJ shaft.

Check oil seal for breakage or deterioration.
Replace it as necessary.
Drive in oil seal until its end contacts stepped surface of drive
shaft joint by using a pipe whose inner diameter is 76 mm (2.992
in.) or more and outer diameter is 80 mm (3.150 in.) or less.

2) Remove piston seal using a thin blade like a thickness gauge,
etc.
CAUTION:
Be careful not to damage inside (bore side) of cylinder.
INSPECTION
Cylinder Boot
Check boots for breakage, crack and damage. If defective, replace.
Piston Seal
Excessive or uneven wear of pad lining may indicate unsmooth re-
turn of the piston. In such a case, replace rubber seal.
ASSEMBLY
Reassemble front brake in reverse order of disassembly, noting the
following points.
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.
Piston Seal
Piston seal is used to seal piston and cylinder and to adjust clear-
ance between pad and disc. Replace with a new one at every over-
haul. Fit piston seal into groove in cylinder taking care not to twist
it.
