FRONT OIL SEAL

Verify identification stamp of replacement frequency put in the lower part of gear carrier to determine
replacement for collapsible spacer when replacing front oil seal. Refer to “Identification stamp of
replacement frequency of front oil seal”. If necessary collapsible spacer replacement, remove final
drive assembly and disassemble it to replace front oil seal and collapsible spacer. Refer to 

DLN-244,

"A/T : Removal and Installation"

 and 

DLN-259, "A/T : Disassembly"

.

NOTE:
The reuse of collapsible spacer is prohibited in principle. However, it is reusable on a one-time basis
only in cases when replacing front oil seal.

Identification stamp of replacement frequency of front oil seal

• The diagonally shaded area in the figure shows stamping point for

replacement frequency of front oil seal.

• The following table shows if collapsible spacer replacement is

NOTE:
Record the preload measurement.

9.

Put matching mark (B) on the end of the drive pinion. The
matching mark (B) should be in line with the matching mark (A)
on companion flange (1).

CAUTION:

For matching mark, use paint. Never damage companion
flange and drive pinion.
NOTE:
The matching mark (A) on the final drive companion flange (1)
indicates the maximum vertical runout position.

10. Remove drive pinion lock nut using the flange wrench.

11. Remove companion flange using pullers.

FRONT OIL SEAL

INSTALLATION

1.

Apply multi-purpose grease to front oil seal lips.

2.

Install front oil seal using the drift (A) [SST: ST30720000 (J-
25405)] as shown in figure.

CAUTION:

• Never reuse oil seal.
• Never incline oil seal when installing.

3.

Align the matching mark (B) of drive pinion with the matching
mark (A) of companion flange (1), and then install the compan-
ion flange (1).

4.

Apply anti-corrosion oil to the thread and seat of new drive pin-
ion 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.

• If the preload torque exceeds the specified value, replace

collapsible spacer and tighten it again to adjust. Never
loosen drive pinion lock nut to adjust the preload torque.

6.

Set a dial indicator (A) vertically to the tip of the drive pinion.

7.

Rotate drive pinion to check for runout.

• If the runout value is still outside of the limit after the phase

has been changed, possible cause will be an assembly mal-
function of drive pinion and pinion bearing and malfunction of
pinion bearing. Check for these items and repair if necessary.

8.

Make a stamping for identification of front oil seal replacement frequency. Refer to “Identification stamp of
replacement frequency of front oil seal”.

CAUTION:

Never make a stamping after replacing front oil seal.

9.

Install propeller shaft. Refer to 

DLN-86, "Removal and Installation"

.

10. Install side flange with the following procedure.
a.

Attach the protector [SST: KV38107900 (J-39352)] to side oil
seal.

b.

After the side flange is inserted and the serrated part of side
gear has engaged the serrated part of flange, remove the pro-
tector.

c.

Put a suitable drift on the center of side flange, then drive it until sound changes.
NOTE:
When installation is completed, driving sound of the side flange turns into a sound which seems to affect
the whole final drive.

d.

Confirm that the dimension of the side flange (1) installation
(Measurement A) in the figure comes into the following.

11. Install drive shaft. Refer to 

RAX-9, "Removal and Installation"

.

12. Install rear wheel sensor. Refer to
