REAR AXLE
DIFFERENTIAL AND CARRIER
Carrier Removal and Disassembly
(1) Remove the axle drive shafts.
(2)
Disconnect the rear universal joint and drop
the propeller shaft.
(3) Remove the lubricant from the axle housing,
using a suction gun.
(4)
Remove the attaching nuts and lift the rear axle
carrier assembly from the axle housing.
(5) Mount the differential in stand DD-1014 and
secure the dial indicator Tool C-430 to the differen-
tial carrier flange so the pointer of the indicator
squarely contacts the back face of the drive gear,
(Fig. 16). Make certain there
is
no end play in the
differential side bearings. If the end play is evident,
remove the adjuster lock and slightly loosen the bear-
ing cap on the gear tooth side. Tighten the adjuster
sufficiently to eliminate the end play.
(6) Rotate the drive gear several complete revolu-
tions while noting the total indicator reading. This
reading must not exceed .005 inch runout. If the in-
dicator reading exceeds the .005 inch runout, it will
be necessary to take a second reading after the drive
gear has been removed. This operation is covered
during the differential disassembly.
(7) With the companion flange up, hold the flange
with holding Tool C-3281 and remove the pinion shaft
nut and Belleville washer.
(8) Install the companion flange puller Tool (2-542
and remove the flange, (Fig. 17).
(9) Install oil seal puller Tool C-748 by screwing it
securely into the pinion oil seal. Tighten the puller
screw to remove the seal.
(10) While holding one hand over the companion
flange end of the carrier, invert the carrier in the

(13) With a
%
inch socket wrench, loosen the bear-
ing cap bolt (one each side) and back off the bearing
adjusters slightly with spanner wrench Tool (2-406, to
remove the differential case bearing preload. Remove
the bearing cap bolts, caps and bearing adjusters.
(14) Remove the differential assembly with bearing
cups. Make certain that each bearing cup remains
with its respective bearing.
(15) Withdraw the pinion and rear bearing cone
from the carrier.

or plates, remove the rear bearing cone from the pin-
ion shaft, (Fig. 19). Remove the pinion locating
washer.
(17) The drive pinion bearing cups can be removed
from the carrier housing with a blunt brass drift and
hammer.
Differen tial Case Disassembly

The front bearing cone shim pack and bearing
spacer (where used) will drop from the carrier.
(11) Apply identifying punch marks on the bearing
supports of the differential carrier, differential bear-
ing caps, and bearing adjusters for reassembly pur--
poses, (Fig. 18).
