grease up to the amount listed below.
7. Install boot securely into grooves (indicated by * marks) shown
in the figure.
CAUTION:
If there is grease on boot mounting surfaces (indicated by *
marks) of joint, boot may come off. Remove all grease from
surfaces.
8. Check that boot installation length “L” is the length indicated
below. Insert a screwdriver or similar tool into smaller side of
boot. Remove air from boot to prevent boot deformation.
CAUTION:
lBoot may break if boot installation length is less than
standard value.
lBe careful that screwdriver tip does not contact inside
surface of boot.

On-Vehicle Inspection and Service
EES00072
LOOSENESS, BACKLASH AND DAMAGE OF MOUNTING PARTS AND CONNECTIONS
Lift vehicle and inspect the following:
lCheck mounting point of each component for looseness, backlash and damage.
lCheck lower ball joint end play.
1. Attach a dial gauge so that the contact rests on the brake caliper.
2. Set front wheels in a straight-ahead position. Do not depress brake pedal.
3. Measure axial endplay by placing an iron pry bar or something similar between transverse link and steer-
ing knuckle.
CAUTION:
Be careful not to damage ball joint boot.
4. If axial endplay is outside the standard, remove transverse link and check lower ball joint.
Wheel AlignmentEES00073
DESCRIPTION
lMeasure wheel alignment under unladen conditions. “Unladen conditions” means that fuel, coolant, and
lubricant are full. However, spare tire, jack, and hand tools should be unloaded.
PRELIMINARY INSPECTION
1. Check the tires for improper air pressure and wear.
2. Check road wheels for runout.
3. Check wheel bearing axial endplay.
4. Check lower ball joint axial endplay.
5. Check strut operation.
6. Check each mounting point of axle and suspension for looseness and deformation.
7. Check each link and arm for cracks, deformation, and other damage.
8. Check the vehicle posture.
INSPECTION OF CAMBER, CASTER, AND KINGPIN INCLINATION ANGLES
lCamber, caster, and kingpin inclination angles cannot be adjusted.
lBefore inspection, mount front wheels onto turning radius gauge. Mount rear wheels onto a stand that has
same height so the vehicle will remain horizontal.
1. Measure camber, caster and kingpin inclination of both right and
left wheels with a suitable alignment gauge.
2. If camber, caster or kingpin inclination is not within specification,
inspect front suspension parts. Replace dam-aged or worn out
parts.

CAUTION:
lDo not overfill.
lRecommended fluid is DEXRONTMIII or equivalent.
Refer toMA-17, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS"
lCheck lines for improper attachment, leaks, cracks, dam-
age, loose connections, chafing and deterioration.
lCheck rack boots for accumulation of power steering fluid.
Axle and Suspension PartsELS000BQ
Check front and rear axle and suspension parts for excessive play,
cracks, wear or other damage.
lShake each wheel to check for excessive play.
lCheck wheel bearings for smooth operation.

Removal and InstallationEDS00052
REMOVAL
1. Put mating marks onto propeller shaft flange yoke and final drive and transfer companion flanges.
CAUTION:
Use paint to avoid scratching the surface.
2. Remove mounting nuts and remove exhaust tube insulator from vehicle.
3. Loosen mounting nuts of center bearing mount brackets (front and rear).
CAUTION:
Tighten nuts temporarily.
4. Remove mounting nuts and bolts from propeller shaft companion flanges, transfer, and final drive.
Remove mounting nuts securing center bearing brackets (front and rear) onto vehicle. Then remove pro-
peller shaft from vehicle.
CAUTION:
If constant velocity joint was bent during propeller shaft assembly removal, installation, or trans-
portation, its boot may be damaged. Wrap boot interference area to metal part with shop cloth or
rubber to protect boot from breakage.
INSPECTION AFTER REMOVAL
1. As shown in the figure, while fixing yoke on one side, check axial
play of joint. If outside the standard, replace propeller shaft
assembly.
2. Check propeller shaft for bend and damage. If damage is
detected, replace propeller shaft assembly.
3. Check center bearing for abnormal noise and damage. If noise
or damage is detected, replace propeller shaft assembly.
CAUTION:
lCenter bearings (front and rear) cannot be disassem-
bled.
lJoints cannot be disassembled.
INSTALLATION
Paying attention to following items, install in the reverse order of removal.
lAlign mating marks to install propeller shaft, and tighten to specified torque.
