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.

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
specified torque. Refer to
.
• 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-192, "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-188, "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-185, "Checking Differential Gear
.
