(5) Clean pinion bearing bores in axle housing thor
oughly. This is important to obtaining correct pinion
gear depth adjustment.
(6) Install starter pinion depth shim in housing rear
bearing cup bore. Be sure shim is centered in bearing
cup bore.
NOTE: If the shim is chamfered, be sure the cham
fered side faces the bottom of the bearing cup bore.
(7) Install rear bearing cup using Tools J-S092 and
J-8608(fig. 2F-37).

(8) Install front bearing cup using Tools J-8092 and
J-8611-01.
(9) Install pinion gear in rear bearing cup.
(10) Install front bearing, rear universal joint yoke,
and original pinion nut on pinion gear. Tighten pinion
nut only enough to remove bearing end play.
NOTE: Do not install a replacement pinion nut and
collapsible spacer at this time as the pinion gear will be
removed after depth measurement.
(11) Note pinion depth variance marked on pinion
gear. If number is preceded by a plus (+) sign, add that
amount (in thousands) to standard setting for axle
model being overhauled. If number is preceded by a
minus (-) sign, subtract that amount (in thousandths)
from standard setting. Result of this addition or sub
traction is desired pinion depth. Record this figure for
future reference.
(12) Assemble Arbor Tool J-5223-4 and Discs J-5223-
23 and install assembled tools in differential bearing cup
bores (fig. 2F-38). Be sure discs are completely seated in
bearing cup bores.
(13) Install bearing caps over discs and install bear
ing cap bolts (fig. 2F-38). Tighten bearing cap bolts se
curely, but not to specified torque.
(14) Position Gauge Block J-5223-20 on end face of
pinion gear with anvil end of gauge block seated on gear
and gauge plunger underneath Arbor Tool J-5223-4 (fig.
2F-39).
