9. Apply differential oil to the side bearings, and assemble new side bearing adjusting shims (2 pieces for
one side) with the same thickness as the ones installed prior to disassembly or re-install the old ones, with
a side bearing outer race to the differential case.
If the side bearing adjusting shims have been already selected, use them.
10. Fit a drift to the right and left side bearing adjusting shims indi-
vidually. Compress differential case assembly and side bearing
to install the carrier case assembly to differential case assembly.
CAUTION:
●A drift shall be placed on the center of the adjusting
shims.
●The pressure shall be as low as possible to install the
carrier case assembly into the differential assembly. The
maximum pressure shall be 1 ton.
●If the adjusting shims are installed by tapping, the carrier
case may be damaged. Avoid tapping.
11. Install a dummy cover set, check and adjust the backlash, drive gear back runout, tooth contact, and over-
all preload torque. Refer to RFD-15, "
Inspection Before Disassembly" .
12. Remove dummy cover set.
13. Apply sealant (Three bond 1217 or the equivalent) around the carrier case mounting surface on the rear
cover.Refer to
CAUTION:
Remove old sealant on the mounting surface, then remove any moisture, oil, and foreign material
on the application and mounting surfaces.
14. Fit a drift to the right and left side bearing adjusting shims indi-
vidually. Compress differential case assembly and side bearing
to install the rear cover.
CAUTION:
●A drift shall be placed on the center of the adjusting
shims.
●The pressure shall be as low as possible to install the
rear cover. The maximum pressure shall be 10kN (1 ton,
1.1US ton, 1.0 Imp ton)
●If the rear cover is forced in by tapping, the rear cover
may be damaged by the adjusting shims. Avoid tapping.
15. Tighten rear cover mounting bolts to the specified torque.
16. Using a drift, drive the oil seal until it becomes flush with the
case end.
CAUTION:
●Oil seals are not reusable. Never reuse them.
●Apply multi-purpose grease onto the oil seal lips, and dif-
ferential oil onto the circumference of the oil seal.
17. Check overall preload torque. Refer to RFD-15, "
OVERALL PRELOAD TORQUE" .

REAR FINAL DRIVE ASSEMBLY
Installation of Electronically Controlled Coupling Assembly
1. Using a drift, install the coupling front bearing to the electroni-
cally controlled coupling.
CAUTION:
At disassembly, be sure to install shim between electroni-
cally-controlled coupling and bearing. Chamfering side of
shim should be coupled to install.
2. Assemble the electronically controlled coupling assembly to the drive pinion.
3. Using a drift, drive an oil seal until it becomes flush with the case
end.
CAUTION:
●Oil seals are not reusable. Never reuse them.
●Apply multi-purpose grease onto the oil seal lips, and dif-
ferential oil onto the circumference of the oil seal.
4. Apply sealant (Three bond 1217 or the equivalent) around the
carrier case mounting surface on the coupling cover.Refer to
RFD-10, "
REAR COVER GASKET" .
CAUTION:
Remove old sealant on the mounting surface, then remove
any moisture, oil, and foreign material from the application
and mounting surfaces.
5. Assemble the coupling cover to the carrier case assembly with
the arrow facing upward, temporarily tighten reamer bolts to the
positions shown in the figure.
6. Tighten the reamer bolts and coupling cover mounting bolts to
the specified torque.
7. Assemble the companion flange.
8. Using a flange wrench, tighten the companion flange nut to the specified torque.
CAUTION:
Do not reuse the companion flange nut.
9. Check companion flange runout. Refer to RFD-17, "
COMPANION FLANGE RUNOUT" .

PRECAUTIONS
PRECAUTIONS
PFP:00001
CautionEES0006Z
●When installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on flat, level ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
●“Unladen condition” means that fuel, coolant and lubricant are full and ready for drive. However, spare tire,
jack, and hand tools should be unloaded.
●After installing the removed suspension parts, always check wheel alignment and adjust if necessary.
●Replace the caulking nut with a new one. Install a new nut without wiping the oil off before tightening.

On-Vehicle Inspection and Service
EES00072
LOOSENESS, BACKLASH AND DAMAGE OF MOUNTING PARTS AND CONNECTIONS
Lift vehicle and inspect the following:
●Check mounting point of each component for looseness, backlash and damage.
●Check 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
●Measure 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
● Camber, caster, and kingpin inclination angles cannot be adjusted.
●Before 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.

Removal and InstallationEES00074
REMOVAL
1. Remove tires. Remove brake caliper and hung it aside.
CAUTION:
Avoid depressing brake pedal with brake caliper removed.
2. Remove electrical wires of ABS wheel speed sensor from strut.
3. Remove brake hose lock plate.
4. Remove mounting bolts and nuts securing steering knuckle to strut.
5. Remove mounting nuts on upper mounting plate and remove upper mounting plate and strut from vehicle.
INSTALLATION
●Refer to FSU-5, "Components" in “Front Suspension Assembly” for tightening torque. Tighten in the
reverse order of removal.
●Be sure arrows on strut mount insulator and spring upper seat
are positioned as shown. Also be sure notch in strut spacer is
positioned as shown. Then install strut.
●Assemble upper mounting plate with its notch facing toward the
outside.
Disassembly and AssemblyEES00075
DISASSEMBLY
1. Install strut attachment to strut and fix it in a vise.
CAUTION:
When installing strut attachment, wrap a shop cloth around
strut to protect it from damage.
2. Slightly loosen piston rod lock nut.
WARNING:
Do not remove piston rod lock nut completely. If it is
removed completely, coil spring jumps out and may cause
serious damage or injury.
3. Compress coil spring using a spring compressor.
WARNING:
Make sure that the pawls of the two spring compressors are firmly hooked on the spring. The
spring compressors must be tightened alternately so as not to tilt the spring.
4. After making sure coil spring is free between upper and lower seats after Step 3. Remove piston rod lock
nut.
5. Remove small parts on strut.
●Remove strut spacer, strut mount insulator, thrust bearing, spring upper seats, and upper rubber seats.
Then remove coil spring.
6. Remove bound bumper from spring upper seat.
7. Gradually release spring compressor, and remove coil spring.
INSPECTION AFTER DISASSEMBLY
Strut
●Check strut for deformation, cracks, and damage, and replace if necessary.
●Check piston rod for damage, uneven wear, and distortion, and replace if necessary.
●Check welded and sealed areas for oil leakage, and replace if necessary.
