FRONT OIL SEAL
8. Remove the front oil seal using Tool as shown.
INSTALLATION
1. Apply multi-purpose grease to the lips of the new front oil seal.
Then drive the new front oil seal in evenly to the gear carrier
using Tool.
CAUTION:
 Do not reuse front oil seal.
 Do not incline the new fron t oil seal when installing.
 Apply multi-purpose grease to the lips 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 th e 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-217, "Disassembly and
Assembly".
 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 sp ecifications, replace the collapsible spacer and
tighten it again to adjust. Refer to DLN-217, "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:Tool number : SP8P
