FRONT OIL SEAL
1. Apply multi-purpose grease to the lips of the new front oil seal.
Then drive the new front oil seal in evenly until it becomes flush
with the gear carrier using Tool.
CAUTION:
• Do not reuse front oil seal.
• Do not incline the new front oil seal when installing.
• Apply multi-purpose grease to the lips of the new front oilseal.
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 preloadtorque 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 DLN-251, "
Disassembly and Assembly".
• Do not loosen drive pinion lock nu t to adjust the total preload torque. If the total preload torque
exceeds the specifications, replace the collapsible spacer and tighten it again to adjust. Refer to
DLN-251, "
Disassembly and Assembly".
• After adjustment, rotate drive pinion back and fo rth 2 to 3 times to check for unusual noise, rota-
tion malfunction, and other malfunctions.
4. Installation of the remaining components is in the reverse order of removal. CAUTION:
Check the differential gear oil level after installation. Refer to DLN-242, "
Checking Differential Gear
Oil".
