DRAINING
1. Stop the engine.
2. Remove the drain plug and gasket from the front final drive
assembly to drain the differential gear oil.
3. Install the drain plug with a new gasket to the front final drive
assembly. Tighten to the specified torque. Refer to
.
CAUTION:
Do not reuse gasket.
FILLING
1. Remove the filler plug and gasket from the front final drive
assembly.
2. Fill the front final drive assembly with new differential gear oil
until the level reaches the specified level near the filler plug hole.
3. Install the filler plug with a new gasket on it to the front final drive assembly. Tighten to the specified
DLN-359, "Disassembly and Assembly"
.
CAUTION:
Do not reuse gasket.
Checking Differential Gear Oil
INFOID:0000000006245178
DIFFERENTIAL GEAR OIL LEAKAGE AND LEVEL
1. Make sure that differential gear oil is not leaking from the front final drive assembly or around it.
2. Check the differential gear oil level from the filler plug hole as
shown.
CAUTION:
Do not start engine while checking differential gear oil level.
3. Install the filler plug with a new gasket on it to the front final drive
assembly. Tighten to the specified torque. Refer to
.
CAUTION:
Do not reuse gasket.

REMOVAL
NOTE:
When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spill-
ing.
1. Remove the drive shafts from the front final drive assembly. Refer to
RAX-8, "Removal and Installation"
.
2. Remove the front propeller shaft from the front final drive assembly. Refer to
.
3. Measure the total preload torque. Refer to
DLN-359, "Disassembly and Assembly"
.
NOTE:
Record the total preload torque measurement.
4. Remove the drive pinion lock nut using suitable tool.
5. Put matching marks on the companion flange and drive pinion
using paint.
CAUTION:
Use paint to make the matching marks. Do not damage the
companion flange or drive pinion.
6. Remove the companion flange using suitable tool.
7. Remove the front oil seal using Tool.

1. Apply multi-purpose grease to the lips and differential gear oil to
the circumference of the new front oil seal. Then drive the new
front oil seal in evenly until it becomes flush with the gear carrier
using Tools.
CAUTION:
• Do not reuse front oil seal.
• Do not incline the new front oil seal when installing.
• Apply multi-purpose grease to the lips and differential
gear oil to the circumference of the new front oil seal.
2. Install the companion flange to the drive pinion while aligning the matching marks.
3. Apply anti-corrosive oil to the threads of the drive pinion and the
seating surface of the new drive pinion lock nut. Then adjust the
drive pinion lock nut tightening torque using suitable tool A, and
check the total preload torque using Tool B.
• The total preload torque should be within the total preload
torque specification. When not replacing the collapsible
spacer, it should also be equal to the measurement taken dur-
ing removal plus an additional 0.56 N·m (0.06 Kg-m, 5 in-lb).
• If the total preload torque is low, tighten the drive pinion lock
nut in 6.8 N·m (0.69 Kg-m, 5ft-lb) increments until the total pre-
load torque is met.
CAUTION:
• Do not reuse drive pinion lock nut.
• Apply anti-corrosive oil to the threads of the drive pinion
and the seating surface of the new drive pinion lock nut.
• Adjust the drive pinion lock nut tightening torque to the
lower limit first. Do not exceed the drive pinion lock nut
.
• Do not loosen drive pinion lock nut to adjust the total preload torque. If the drive pinion lock nut
torque or the total preload torque exceeds the specifications, replace the collapsible spacer and
tighten it again to adjust. Refer to
DLN-359, "Disassembly and Assembly"
• After adjustment, rotate drive pinion back and forth 2 to 3 times to check for unusual noise, rota-
tion malfunction, and other malfunctions.
4. Install new side oil seals into the front final drive assembly. Refer to
DLN-354, "Removal and Installation"
.
5. Installation of the remaining components is in the reverse order of removal.
CAUTION:
Check the differential gear oil level after installation. Refer to
DLN-351, "Checking Differential Gear
.
