If the standard is not satisfied, adjust by turning the adjust-
ing nut to move the differential case ASSY in the thrust di-
rection.
(1) When the backlash is excessive:
Loosen the adjusting nut on the ring gear teeth side
and tighten the adjusting nut on the rear side as much
to bring the ring gear closer to the drive pinion.
(2) When the backlash is insufficient:
Loosen the adjusting nut of the rear side of the ring
gear and tighten the adjusting nut on the teeth side as
much to bring the ring gear away from the drive pin-
ion.
7. Side bearing starting torque (Reference only):
Measure the torque by turning the output gear lock nut
with a torque wrench.
Standard:

11. Check the tooth contact.
(1) Uniformly coat red lead thinly on both faces of 7 to 8
gear teeth, and turn the ring gear forward and back-
ward several times after installing a box wrench on
the output gear lock nut. Judge the gear teeth contact
by observing the pattern formed on the gear teeth. If
the tooth contact is not correct, make adjustment ac-
cording to the "Drive Pinion Protrusion Adjustment"
and "Ring Gear Backlash and Differential Case Bear-
ing Starting Torque Adjustment" procedures.
(2) Correct teeth contact
The pattern should be slightly leaning to the inside circle
contact of the ring gear with respect to the center of the tooth
length, as shown.
(3) Heeal contact
Move the drive pinion croser to the ring gear by de-
creasing the drive pinion adjusting shim thickness.
Then move the ring gear away from the pinion to ad-
just the backlash.
(4) Toe contact
Move the pinion away from the ring gear by increasing
the drive pinion adjusting shim thickness. Then move
the ring gear closer to the pinion to adjust the back-
lash.
