(7) Install new pinion nut. Tighten nut to 210 foot
pounds (285 N«m) torque on Model 30 and 44 axles, and
260 foot-pounds (352 N«m) torque on Model 60 axles.
Differential Side Gear Adjustment
(1) Install thrust washers on side gears and install
gears in case.
(2) Install thrust washers on differential pinion
gears and install gears in case.
(3) Install thrust block and pinion mate shaft pin in
case.
(4) Position differential case on end.
(5) Tap differential case lightly on flat surface to
settle gears into position in case.
(6) Measure clearance between case and side gears
using feeler gauges (fig. 2F-56). Clearance between gears
and case must be 0.000 to 0.006 inch (0.00 to 0.15 mm).

Fig. 2F-56 Checking Side Gear Clearance
(7) If clearance between gears and case exceeds
0.006 inch, replace complete differential case.
NOTE: Shims are no longer available.
(8) If differential case is replaced, check side gear
clearance again.
(9) Install ring gear on differential case and start
two bolts in holes 180 degrees apart. Tighten bolts
evenly to seat ring gear.
(10) Install remaining bolts and tighten to 55 foot
pounds (74 N»m) torque.
Differential Bearing Preload and Ring Gear Backlash Adjustment
NOTE: Differential bearing preload is controlled by
shims located between the differential case and
bearings.
(1) Remove old differential bearing shims if not
removed previously.
(2) Install differential bearings. On Model 30 and 44
axles, install bearings using Driver Handle J-7079-02
and Installer J-22175 (fig. 2F-57). On Model 60 axles,
install bearings using Driver Handle and Installer J-
24430.
(3) Install bearing cups on differential bearings.
(4) Install differential in axle housing.
(5) Install bearing caps and tighten cap bolts se
curely but not to specified torque.
(6) Hold ring gear in contact with pinion gear and
pry differential bearing cups toward center of case using
screwdriver.
(7) Insert various thickness feeler gauges between
each bearing cup and axle housing until ring gear back
lash is 0.001 to 0.002 inch (0.02 to 0.05 mm) with feeler
gauges installed. Feeler gauges must be installed at both
sides of differential and at same time to obtain accurate
measurement.
(8) Assemble shim pack that will provide desired
backlash. Check backlash again. If OK, tag and retain
shims for assembly.
(9) Remove differential case.
