7. INSPECT RUNOUT OF TRANSMISSION COUPLING
ASSEMBLY
(a) Install a dial gauge so that it is perpendicular to the
inner side of the transmission coupling.
(b) Using SST, rotate the transmission coupling
assembly forward and backward and measure the
vertical runout.
SST 09564-32011
Maximum vertical runout :
0.06 mm (0.0024 in.)
(c) Install a dial gauge perpendicularly onto the
transmission coupling assembly, as shown in the
illustration.
(d) Using SST, rotate the transmission coupling
assembly forward and backward and measure the
lateral runout.
SST 09564-32011
Maximum lateral runout:
0.07 mm (0.0028)
8. REMOVE ELECTROMAGNETIC COUPLING
(a) Remove the 4 bolts and, using a plastic-faced
hammer, lightly tap the rear differential carrier cover
to remove it from the rear differential carrier.
NOTICE:
Set the brass bar on the ribbed part of the rear
differential carrier cover.
9. REMOVE 4WD LINEAR SOLENOID
(a) Using a snap ring expander, remove the snap ring.
(b) Remove the solenoid from the yoke.
(c) Remove the O-ring from the solenoid.

10. REMOVE YOKE
(a) Using a 5 mm socket hexagon wrench, remove the
3 bolts and yoke from the differential carrier.
11. REMOVE TRANSMISSION COUPLING CONICAL
SPRING WASHER
(a) Remove the spring washer from the differential
carrier.
12. REMOVE TRANSMISSION COUPLING SHIM
(a) Remove the shim from the differential carrier.
13. INSPECT DIFFERENTIAL RING GEAR BACKLASH
(a) Insert a dial gauge through the rear differential
carrier cover plug hole, and set it perpendicular to
the ring gear tooth surface's tip.
(b) Using SST, fix the drive pinion in place.
SST 09556-16011
(c) Using SST, rotate the rear differential case forward
and backward, and measure the backlash.
SST 09564-32011
Standard backlash:
0.09 to 0.16 mm (0.0034 to 0.0063 in.)
NOTICE:
Measure at 3 or more areas around the
circumference of the ring gear.

REMOVAL
1. REMOVE REAR WHEEL
2. DISCONNECT CABLE FROM NEGATIVE BATTERY
TERMINAL
CAUTION:
Wait at least 90 seconds after disconnecting the
cable from the negative (-) battery terminal to
prevent airbag and seat belt pretensioner activation.
3. REMOVE REAR AXLE SHAFT NUT (for 4WD)
(a) Using SST and hammer, unstake the staked part of
the nut.
SST 09930-00010
NOTICE:
Loosen the staked part of the nut completely,
otherwise the screw of the drive shaft may be
damaged.
(b) While applying the brake, remove the lock axle hub
nut.
4. REMOVE REAR DISC BRAKE CYLINDER ASSEMBLY
LH (See page BR-55)
5. REMOVE REAR DISC (See page BR-57)
6. REMOVE SKID CONTROL SENSOR WIRE (for 2WD)
(See page BC-198)
7. REMOVE REAR SPEED SENSOR LH (for 4WD) (See
page BC-205)
8. REMOVE REAR SUSPENSION NO. 1 ARM
ASSEMBLY LH (See page SP-42)
9. DISCONNECT REAR SHOCK ABSORBER
ASSEMBLY LH
(a) Remove the 2 bolts and disconnect the shock
absorber with bracket from the axle carrier.
10. REMOVE REAR AXLE HUB AND BEARING
ASSEMBLY LH
(a) fro 2WD:
(1) Remove the 4 bolts, and axle hub and the
bearing from the axle carrier.
NOTICE:
Do not place the hub and bearing's magnet
rotor side so that it is facing downward, and
do not allow the magnet rotor side to
become damaged or contact foreign matter.
