(15) Check torque required to turn pinion, gear Pin-
ion must be turned several revolutions to obtain accu-
rate torque reading. Refer to torque reading recorded
during disassembly and add 5 inch-pounds (0.6 N*m)
for proper amount of torque.
(16) If preload torque is less than desired amount,
which should equal disassembly torque reading plus 5
inch-pounds (0.6 N*m), tighten pinion nut slightly and
recheck torque.
(17) Repeat gradual tightening procedure until de-
sired torque is attained. Do not loosen and retighten
nut.
CAUTION: Do not overtighten the pinion nut. If the
desired torque is exceeded, a replacement collapsible
pinion spacer sleeve must be installed and the pinion
gear preload reset. Refer to Differential Overhaul.
(18) Install propeller shaft. Align index marks made
at disassembly
(19) Install rear brake drums and wheels.
(20) Remove supports and lower vehicle.

Pinion Seal Installation
Installation
(1) Install replacement pinion seal using tool J-
25104.
(2) Install yoke on pinion.
(3) Install pinion washer and nut. Tighten nut to
210 foot-pounds (285 N*m) torque on Model 44 axle and
260 foot-pounds (352 N*m) torque on Model 60 axle.
(4) Align index marks on propeller shaft and yoke
and install shaft. Tighten U-bolt nuts to 16 foot-pounds
(22 N*m) torque or tighten flange bolts to 35 foot-pounds
(47 N»m) torque.
(5) Remove supports and lower vehicle.
REAR AXLE REM0IAL " .
(1) Raise vehicle and position support stands under
frame rails just forward of rear springs.
(2) Remove wheels.
(3) Mark propeller shaft and axle for assembly
alignment reference.
(4) Disconnect propeller shaft at rear axle yoke.
(5) Disconnect shock absorbers at axle tubes.
(6) Disconnect brake hydraulic hose at rear axle tee
fitting. Tape ends of hose and fitting to prevent dirt
entry.
(7) Disconnect parking brake cable at equalizer.
(8) Support axle using hydraulic jack.
(9) Remove U-bolts. On vehicle with spring-
mounted above axle, disconnect spring at rear shackle.
(10) Slide axle from under vehicle.

N O T E : All service replacement axle assemblies are
shipped from the factory without lubricant in the differ-
ential. Lubricant must be added to the differential be-
fore the axle is installed. Use gear lubricant grade SAE
