FRONT OIL SEAL
INSTALLATION
1. Apply multi-purpose grease to front oil seal lips.
2. Using the drifts, install front oil seal as shown in figure.CAUTION:
• Never reuse oil seal.
 When installing, n ever incline oil seal.
3. Align the matching mark (B) of drive pinion with the matching mark (A) of companion flange, and then install the companion
flange (1).
4. Apply anti-corrosion oil to the thread and seat of new drive pinion lock nut, and temporarily tighten drive
pinion lock nut to drive pinion.
CAUTION:
Never reuse drive pinion lock nut.
5. Tighten to drive pinion lock nut, while adjust total preload torque.
CAUTION:
 Adjust to the lower limit of the drive pinion lock nut tight-
ening torque first.
 After adjustment, rotate dri ve pinion back and forth 2 to 3
times to check for unusual no ise, rotation malfunction,
and other malfunctions.
 If measured value is out of the specification, remove final drive assembly and disassemble drive pinion parts to check and
adjust each part. Refer to FFD-14, "
Removal and Installation
(VQ35DE Models)",FFD-15, "Removal and Installation
(VK45DE Models)" and FFD-17, "Disassembly and Assem-
bly".
6. Install front propeller shaft. Refer to PR-4, "
Removal and Instal-
lation".
7. Install side shaft assembly.
8. Install front drive shaft both. Refer to FAX-15, "
Removal and Installation (Left Side)", FAX-16, "Removal
and Installation (Right Side)".
