FRONT OIL SEAL
2007 Pathfinder
INSTALLATION
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 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
preload 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
FFD-15, "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
FFD-11, "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
FFD-8, "Checking Differential Gear

ASSEMBLY INSPECTION AND ADJUSTMENT
●
Drain the differential gear oil before inspection and adjustment. Refer to
●
Remove and install the carrier cover as necessary for inspection and adjustment. Refer to
Total Preload Torque
1.
Install the differential side shaft if necessary. Refer to
FFD-33, "Differential side shaft"
CAUTION:
The differential side shaft must be installed in order to measure total preload torque.
2.
Rotate the drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
3.
Rotate the drive pinion at least 20 times to check for smooth operation of the bearings.
4.
Measure total preload torque using Tool.
NOTE:
Total preload torque = Drive pinion bearing preload torque +
Side bearing preload torque
●
If the measured value is out of the specification, check and adjust each part. Adjust the drive pinion
bearing preload torque first, then adjust the side bearing preload torque.
CAUTION:
Select a side bearing adjusting washer for right and left individually.
Drive Gear Runout
1.
Fit a dial indicator to the drive gear back face.
2.
Rotate the drive gear to measure runout.
●
If the runout is outside of the limit, check the condition of the
drive gear assembly. Foreign material may be caught between
the drive gear and differential case, or the differential case or
drive gear may be deformed.
CAUTION:
Replace drive gear and drive pinion as a set.

Tighten the drive pinion lock nut.
On side bearings:
Use thicker side bearing adjusting washers by the same
amount on each side. Refer to
FFD-35, "Side Bearing Adjusting
