TOOL
J-22661
Fig. 2F-28 Pinion Seal Installation
(13) Install yoke on pinion. Note alignment marks.
(14) Install replacement pinion nut. Tighten nut us
ing Tools J-8614-01 and J-22575 to remove pinion bearing
end play only. Do not overtighten nut.
(15) Check torque required to turn pinion gear. Pin
ion gear must be turned several revolutions to obtain
accurate torque reading. Refer to torque reading re
corded during disassembly and add 5 inch-pounds (0.56
N»m) more torque to this amount for correct preload
torque.
(16) If preload torque is less than desired amount,
which should equal disassembly torque reading plus 5
inch-pounds (0.56 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 AND YOKE—MODEL 44 AND 60 AXLE
Removal
(1) Raise and support vehicle.
(2) Index propeller shaft to front yoke for assembly
reference and disconnect shaft at yoke.
(3) Remove pinion nut and washer using Tool
J-8614-01 (fig. 2F-3).
(4) Remove yoke using Tools J-8614-01, -02. -03 (fig.
2F-4).
AXLES - FRONT HUBS 2F-19
(5) Remove pinion seal using Tool J-25180 on Model
44 axle or Tool J-25144 on Model 60 axle.
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 strip clamp bolts 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 REMOVAL
(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.
REAR AXLE INSTALLATION
NOTE: All service replacement axle assemblies are
shippedfrom the factory without lubricant in the differ
ential. Lubricant must be added to the differential be
fore the axle is installed. Use Jeep Axle Lubricant, or
equivalent, marked SAE 85W-90 gear lubricant, grade
API GL-5.
When adding differential lubricant, be sure the pinion
bearings receive lubricant. Suspend the axle so the axle
shafts are in a horizontal position and the yoke end of
the pinion housing is facing downward. Then, turn the
pinion gear several times so lubricant will reach the
pinion bearings.
(1) Support axle assembly on hydraulic jack and
position assembly under vehicle.
(2) Align springs with axle spring pads, and install
U-bolts and nuts. On vehicles with spring mounted
above axle, position spring on shackles and install bolts
but do not tighten bolts completely.
(3) Attach brake line hose at tee fitting on top of
housing.
