into gear carrier.
12. Measure side bearing preload. If necessary, select the appropri-
ate side bearing adjusting washers. Refer to
13. Insert selected left and right side bearing adjusting washers in
place between side bearings and gear carrier.
14. Align matching marks on bearing cap with that on gear carrier.

●
Do not reuse oil seal.
●
When installing, do not incline oil seal.
●
Apply multi-purpose grease onto oil seal lips, and gear
oil onto the circumference of oil seal.
17. Check and adjust drive gear runout, tooth contact, drive gear to
drive pinion backlash, and total preload torque. Refer to
RFD-19, "Total Preload Torque"
Recheck above items. Readjust the above description, if necessary.
18. Apply sealant to mating surface of rear cover.
●
Use Genuine Silicone RTV or equivalent. Refer to
"RECOMMENDED CHEMICAL PRODUCTS AND SEAL-
ANTS"
.
CAUTION:
Remove old sealant adhering to mounting surfaces. Also
remove any moisture, oil, or foreign material adhering to
application and mounting surfaces.
19. Install rear cover on gear carrier and tighten mounting bolts with
the specified torque. Refer to
20. Install side flange with the following procedure.
a.
Attach the protector 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 installation (Mea-
