TOOTH CONTACT
1.
Remove rear cover. Refer to
.
2.
Following the procedure below, install a dummy cover set (SST: KV389L0010) to gear carrier.
a.
Set dummy cover shims to the right and left side bearing adjusting shims.
b.
Temporarily tighten dummy cover to gear carrier.
c.
Position dummy cover spacers to dummy cover.
d.
Tighten rear cover mounting bolts to the specified torque. Refer to
.
e.
Tighten dummy cover spacer mounting bolts evenly to the specified torque.
3.
Apply red lead to drive gear.
CAUTION:
Apply red lead to both the faces of 3 to 4 gears at 4 loca-
tions evenly spaced on drive gear.
4.
Rotate drive gear back and forth several times, check drive pin-
ion gear to drive gear tooth contact.
CAUTION:
Check tooth contact on drive side and reverse side.

DRIVE PINION
Tooth Contact Judgment Guide
5.
If tooth contact is improperly adjusted, follow the procedure
below to adjust the pinion height (dimension X).
• If the tooth contact is near the face (face contact), or near the
heel (heel contact), thicken drive pinion gear adjusting shim to
move drive pinion closer to drive gear.

• If the tooth contact is near the flank (flank contact), or near the
toe (toe contact), thin drive pinion gear adjusting shim to move
drive pinion farther from drive gear.
BACKLASH
1.
Remove rear cover. Refer to
.
2.
Following the procedure below, install a dummy cover set (SST: KV389L0010) to gear carrier.
a.
Set dummy cover shims to the right and left side bearing adjusting shims.
b.
Temporarily tighten dummy cover to gear carrier.
c.
Position dummy cover spacers to dummy cover.
d.
Tighten rear cover mounting bolts to the specified torque. Refer to
.
e.
Tighten dummy cover spacer mounting bolts evenly to the specified torque.
3.
Fit a dial indicator to the drive gear face to measure the back-
lash.
• If the backlash is outside of the specified value, change the
thickness of side bearing adjusting shims.
Inspection After Disassembly
INFOID:0000000010288422
Clean up the disassembled parts. Then, inspect if the parts are worn or damaged. If so, follow the measures
below.
PDIA0441E
: 5.9 N·m (0.6 kg-m, 52 in-lb)
Standard
Backlash
: Refer to
.
When the backlash is large:
Make drive gear back adjusting shims thicker, and drive
gear front adjusting shims thinner.
When the backlash is small:
Make drive gear back adjusting shims thinner, and
drive gear front adjusting shims thicker.

Conditions and Measures
Hypoid gear
• If the gear teeth do not mesh or line-up correctly, determine the cause and adjust or replace as nec-
essary.
• If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new
drive gear and drive pinion as a set.
Bearing
If any chipped (by friction), pitted, worn, rusted or scratched mark, or unusual noise from the bearing is
observed, replace as a bearing assembly (as a new set).
Side gear and Pinion mate
gear
• If any cracks or damage on the surface of the tooth is found, replace.
• If any worn or chipped mark on the contact sides of the thrust washer is found, replace.
Side gear thrust washer and
pinion mate thrust washer
If it is chipped (by friction), damaged, or unusually worn, replace.

Differential case
If any wear or crack on the contact sides of the differential case is found, replace.
Companion flange
If any chipped mark (about 0.1 mm, 0.004 in) or other damage on the contact sides of the lips of the com-
panion flange is found, replace.
