• If the runout is outside of the repair limit, check drive gear
assembly condition; foreign material may be caught between
drive gear and differential case, or differential case or drive
gear may be deformed, etc.
CAUTION:
Replace drive gear and drive pinion as a set.

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.

)] to gear carrier.
c.
Position dummy cover spacers [SST: KV38108621 (
—
)] to dummy cover [SST: KV38108610
(
—
)].
d.
Tighten rear cover mounting bolts to the specified torque. Refer to
.
e.

lash.
• If the backlash is outside of the specified value, change the
thickness of side bearing adjusting shims.
Inspection After Disassembly
INFOID:0000000005514273
DRIVE GEAR AND DRIVE PINION
• Clean up the disassembled parts.
• If the gear teeth never mesh or line-up correctly, determine the cause and adjust or replace as necessary.
• 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
• Clean up the disassembled parts.
• If any chipped (by friction), pitted, worn, rusted or scratched marks, or unusual noise from the bearing is
observed, replace as a bearing assembly (as a new set).
