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
"A/T : Removal and Installation"
.
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
needed before replacing front oil seal.
When collapsible spacer replacement is required, disassemble
final drive assembly to replace collapsible spacer and front oil seal.
Refer to
.
CAUTION:
Never make a stamping after replacing front oil seal.
• After replacing front oil seal, make a stamping on the stamping point in accordance with the table below in
order to identify replacement frequency.
CAUTION:
Stamping shall be made from left to right.

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.

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"
.
