Pre-inspection
Before disassembling ®nal drive, perform the following inspection.
+Total preload
1) Turn drive pinion in both directions several times to set bearing
rollers.
2) Check total preload with Tool.
Tool number: ST3127S000
Total preload (with front oil seal):
Drive pinion bearing
New parts
1.7 - 2.5 Nzm (17 - 25 kg-cm, 15 - 22 in-lb)
Used parts
1.5 - 1.7 Nzm (15 - 17 kg-cm, 13 - 15 in-lb)
+Ring gear to drive pinion backlash
Check ring gear-to-drive pinion backlash with a dial indicator at
several points.
Ring gear-to-drive pinion backlash:
0.15 - 0.20 mm (0.0059 - 0.0079 in)
+Ring gear runout
Check runout of ring gear with a dial indicator.
Runout limit:
0.08 mm (0.0031 in)
+Tooth contact
Check tooth contact. Refer to ADJUSTMENT (PD-27).
+Side gear to pinion mate gear backlash
Measure clearance between side gear thrust washer and dif-
ferential case with a feeler gauge.
Clearance between side gear thrust washer and differ-
ential case:
0.15 - 0.20 mm (0.0059 - 0.0079 in)

Adjustment
FRICTION DISC AND FRICTION PLATE END PLAY
End play of friction disc and friction plate can be calculated by using
following equation and should be adjusted within following range.
Adjustment can be made by selecting friction disc having two dif-
ferent thicknesses.
End play E:
0.05 - 0.15 mm (0.0020 - 0.0059 in)
E=Aþ(B+C)
A: Length of differential case contact surface to differen-
tial case inner bottom.
B: Total thickness of friction discs, friction plates, spring
disc and spring plate in differential case on one side.
C: Length of differential case contact surface to back side
of side gear.
1. Measure values of ``A''.
Standard length A:
49.50 - 49.55 mm (1.9488 - 1.9508 in)
2. Measure thickness of each disc and plate.
Total thickness ``B'':
19.24 - 20.26 mm (0.7575 - 0.7976 in)
3. Measure values of ``C''.
(1) Attach a dial indicator to the base plate.
(2) Place differential case B on the base plate, and install a mas-
ter gauge on case B.
Then adjust the dial indicator scale to zero with its tip on the
master gauge.

(3) Install pinion mate gears, side gears and pinion mate shaft in
differential case B.
(4) Set dial indicator's tip on the side gear, and read the indication.
Example:
E = A þ D = A þ (B + C) = 0.05 to 0.15 mm
A = 49.52 mm
B = 19.45 mm
C = 29.7 mm
D=B+C E=AþD
B .... 19.45 A ..... 49.52
+C .... 29.7 þD .... 49.15
49.150.37
From the above equation, end play of 0.37 mm exceeds the speci-
®ed range of 0.05 to 0.15 mm.
Select suitable discs and plates to adjust correctly.
Assembly
Assemble differential case in the reverse order of disassembly,
observing the following.
1. As an aid to installation, apply sufficient amounts of recom-
mended limited slip differential gear oil (refer to MA section) to
the faces of pressure rings, discs and plates to be assembled
together.
2. Place differential case B on a level surface, then install thrust
washer.
3. Install spring plates, friction plates and friction discs.
Pay particular attention to the direction of clutch plates and
their assembly sequence.

14. Tighten side bearing cap bolts.
15. Install side lock ®nger in place to prevent rotation during opera-
tion.
16. Check runout of ring gear with a dial indicator.
Runout limit: 0.08 mm (0.0031 in)
+If backlash varies excessively in different places, the variance
may have resulted from foreign matter caught between the ring
gear and the differential case.
+If the backlash varies greatly when the runout of the ring gear
is within a speci®ed range, the hypoid gear set or differential
case should be replaced.
17. Check tooth contact. Refer to ADJUSTMENT (PD-27).

DIFFERENTIAL LOCK INDICATOR SWITCH CHECK
+Check switch function by checking continuity.
Continuity:
ON Continuity should exist.
OFF Continuity should not exist.
If NG, replace differential lock indicator switch.
DIFFERENTIAL LOCK SOLENOID CHECK
1. Disconnect differential lock solenoid 4-pin connector.
2. Check continuity between terminals
V1andV3,V2andV4.
Continuity should exist.
If NG, replace differential lock solenoid.
SPEED SENSOR CHECK
Refer to EL section.

DIFFERENTIAL LOCK CONTROL UNIT CHECK
On-vehicle check
Be sure that vehicle is in 4WD.
Operate vehicle at a speed less than 7 km/h (4 MPH) or
when stopping.
Turn differential lock switch ON.
Ensure differential lock indicator lamp is on.
Ye s
cNo
Malfunction is in system other than differential lock con-
trol unit, speed sensor. Check and correct.
Turn differential lock switch OFF while driving vehicle at
speed less than 7 km/h (4 MPH) or when stopping.
Drive vehicle at speed greater than 7 km/h (4 MPH) and
turn differential lock switch ON.
Ensure differential lock indicator lamp is on.
No
cYe s
When speed sensor functions, differential lock control
unit functions improperly.
Differential lock control unit is functioning properly.Check differential lock control unit.
Unit check
1. Ensure that wiring to differential lock control unit is correct and
that the unit is properly connected to power supply.
2. Place vehicle on a safety stand properly. Ensure that the front
and rear wheels rotate freely.
3. Check output voltage of differential lock at solenoid-2 connec-
tor.
+Vehicle speed less than 7 km/h (4 MPH) on speedometer
Power supply: Approximately 12V
+Vehicle speed greater than 7 km/h (4 MPH) on speedometer
Output voltage: Approximately 0V
