REMOVAL

1. Separate the (RH) and (LH) drive shafts from the front final drive assembly. Properly support the drive

shafts. Refer to 

FAX-8, "Removal and Installation"

 for companion flange bolt torque specification.

2. Remove the front propeller shaft. Refer to 

DLN-130, "Removal and Installation"

.

3. Measure the total preload torque. Refer to 

DLN-185, "Inspection and Adjustment"

.

NOTE:

Record the total preload torque measurement.

4. Remove the drive pinion lock nut using suitable tool.
5. Put matching marks on the companion flange and drive pinion

using paint.

CAUTION:

Use paint to make the matching marks. Do not damage the

companion flange or drive pinion.

6. Remove companion flange using suitable tool.

7. Place a small hole in the front oil seal case using suitable tool.

8. Remove the front oil seal using suitable 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 front 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, 60 in-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 

DLN-169, "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 specifications, replace the collapsible spacer and

tighten it again to adjust. Refer to 

DLN-169, "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 

DLN-162, "Checking Differential Gear

Oil"

.

REMOVAL

1. Drain differential gear oil. Refer to 

DLN-162, "Changing Differential Gear Oil"

.

2. Remove the front final drive assembly. Refer to 

DLN-167, "Removal and Installation"

.

3. Remove the carrier cover bolts and separate the carrier cover

from the gear carrier using Tool.

CAUTION:

• Do not damage the mating surface.

• Do not insert flat-bladed screwdriver, this will damage the

mating surface.

INSTALLATION

1. Apply 3 mm (0.12 in) bead of sealant to the mating surface of

the carrier cover as shown.

• Use Genuine Silicone RTV or equivalent. Refer to 

GI-21,

"Recommended Chemical Products and Sealants"

.

CAUTION:

Remove any old sealant adhering to the mating surfaces.

Also remove any moisture, oil, or foreign material adhering

to the application and mating surfaces.

2. Install the carrier cover to the gear carrier. Tighten the bolts to

the specified torque. Refer to 

DLN-169, "Disassembly and

Assembly"

.

3. Install the front final drive assembly. Refer to 

DLN-167,
