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 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 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 

RFD-18, "COMPONENTS"

 .

●

Do not loosen drive pinion lock nut 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

RFD-18, "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.

Installation of the remaining components is in the reverse order of removal.

CAUTION:

Check the differential gear oil level after installation. Refer to 

RFD-9, "Checking Differential Gear

Oil"

 .

  for VDC/TCS/ABS or 

BRC-

128, "Removal and Installation"

  for HDC/HSA/VDC/TCS/ABS.

CAUTION:

Do not to damage gear carrier.

INSTALLATION

1.

Apply multi-purpose grease to the lips and differential gear oil to
the circumference of the new side oil seal. Then drive the new
side oil seal in evenly until it becomes flush with the gear carrier
using Tool.

CAUTION:

●

Do not reuse side oil seal.

●

Do not incline the new side oil seal when installing.

●

Apply multi-purpose grease to the lips and differential
gear oil to the circumference of the new side oil seal.

2.

Install the side flange using Tool.

a.

Install the Tool to the side oil seal as shown.

b.

Insert the side flange until the serrated part of the side flange
has engaged the serrated part of the side gear and remove the
Tool.

c.

Drive in the side flange using suitable tool.

NOTE:
Installation is completed when the driving sound of the side
flange turns into a sound which seems to affect the whole rear
final drive assembly.
