REAR AXLE – Rear Hub Assembly27-34
INSTALLATION SERVICE POINT
ADRIVE SHAFT NUT INSTALLATION
(1) Install the washer on the drive shaft in the direction shown
on the left.
(2) Using the special tool, tighten the drive shaft nut to the
specified torque.
Caution
Before torquing the drive shaft nut to specification,
do not apply vehicle weight to the wheel bearing.
(3) If, at this time, the split pin holes are not aligned, tighten
the nut further (within 255 Nm {26.0 kgf
m}), insert the
split pin in the first matching holes, and bend it securely.
INSPECTION
1. REAR WHEEL BEARING ROTATION STARTING
TORQUE
(1) Install the special tool to the rear hub assembly and tighten
it to the specified torque.
(2) Using the special tool, measure the wheel bearing rotation
starting torque.
Limit: 1.0 Nm {10.5 kgf
cm}
(3) The wheel bearing starting torque should be within the
limit and the hub should be free of binding or rough motion
when turned.
2. WHEEL BEARING AXIAL PLAY CHECK
(1) Check the wheel bearing for axial play.
Limit: 0.05 mm
(2) If the specified torquing range (196 to 255 Nm {20.0
to 26.0 kgf
m}) does not bring the wheel bearing axial
play into the limit, replace the rear hub assembly.

DISASSEMBLY SERVICE POINT
ASCREW REMOVAL
(1) Check out the alignment marks.
(2) Loosen a uniform amount little by little the screws securing
differential case A to B.
(3) Separate differential case B from differential case A and
remove their components.
Keep the removed spring plates, friction plates, and friction
discs organized in the order of removal and for right and
left use.

REAR AXLE – LSD Case Assembly 27-48
BSCREW TIGHTENING
(1) Align the alignment mark on differential case A with that
on differential case B.
(2) Tighten the screws connecting differential case A and
B a uniform amount little by little in the diagonal order.
NOTE
If tightening the screws does not bring the two cases
properly together, spring plates are not probably
assembled properly. Reassemble from the start.
CLSD DIFFERENTIAL TORQUE CHECK
(1) Using the special tool, check for differential torque.
Standard value:
When new clutch plate is
installed Nm {kgf
m}When existing clutch plate is
reused Nm {kgf
m}
5 – 19 {0.5 – 1.9}2 – 19 {0.2 – 1.9}
NOTE
Before measuring the differential torque, first turn the
gears so they snug each other, then take measurements
during rotation.
(2) If the measurement falls outside the specified range,
disassemble the differential case assembly and repair
or replace defective parts.
INSPECTION
1. DIFFERENTIAL CASE INTERNAL PARTS
CONTACT/SLIDING SURFACE CHECK
(1) Clean the disassembled parts with cleaning oil and dry
them with compressed air.
(2) Check each plate, disc, and pressure ring for the following:
A. Friction and sliding surfaces of friction discs, friction
plates, and spring plates.
Replace a defective part with heat discoloration and
excessive wear with a new one, as it degrades locking
performance.
NOTE
If the inner periphery of the friction face shows traces
of harsh contact, it is because of the spring tension
of each plate, disc and other part. Do not confuse
this with abnormal wear.
B. Inner periphery and outer periphery protrusions of
friction discs, friction plates, and spring plates.
Replace a cracked or damaged part with a new one.
C. Friction and sliding surfaces between pressure rings
and friction discs.
