Dodge Dakota (R1). Manual — part 219
AXLE BEARINGS
REMOVAL
(1) Remove axle shaft.
(2) Remove axle shaft seal from the end of the axle
tube with a small pry bar (Fig. 16).
NOTE: The seal and bearing can be removed at the
same time with the bearing removal tool.
(3) Remove the axle shaft bearing from the axle
tube with Bearing Removal Tool Set 6310, using
Adapter Foot 6310-9 (Fig. 17).
INSTALLATION
(1) Wipe the axle tube bore clean. Remove any old
sealer or burrs from the tube.
(2) Install the axle shaft bearing with Installer
C-4198 and Handle C-4171 (Fig. 18). Install the bear-
ing with the bearing part number against the
installer. Verify the bearing in installed straight and
the tool fully contacts the axle tube when seating the
bearing.
(3) Install a new axle seal with Installer C-4076-B
and Handle C-4735-1. When the tool contacts the
axle tube, the seal is installed to the correct depth.
(4) Coat the lip of the seal with axle lubricant for
protection prior to installing the axle shaft.
(5) Install the axle shaft.

AXLE SHAFT SEALS
REMOVAL
(1) Remove axle shaft.
(2) Remove axle shaft seal from the end of the axle
tube with a small pry bar (Fig. 19).
INSTALLATION
(1) Wipe the axle tube bore clean. Remove any old
sealer or burrs from the tube.
(2) Install a new axle seal with Installer C-4076-B
and Handle C-4735-1 (Fig. 20). When the tool con-
tacts the axle tube, the seal is installed to the correct
depth.
(3) Coat the lip of the seal with axle lubricant for
protection prior to installing the axle shaft.
(4) Install the axle shaft.
PINION SEAL
REMOVAL
(1) Raise and support the vehicle.
(2) Remove the wheel and tire assemblies.
(3) Mark the universal joint, companion flange,
and pinion shaft for installation reference.
(4) Remove propeller shaft from the companion
flange. Secure the propeller shaft in an upright posi-
tion to prevent damage to the rear universal joint.
(5) Remove the brake drums to prevent any drag.
(6) Rotate the companion flange three or four
times.
(7) Record pinion rotating torque with an inch
poundtorque wrench for installation reference.
(8) Install socket head bolts into two of the
threaded holes in the companion flange, 180° apart.
(9) Position Holder 6719A against the companion
flange and install a hex head bolt and washer into
one of the remaining threaded holes. Tighten the bolt
and washer so that the Holder 6719 is held to the
flange.
(10) Hold the flange with Holder 6719A and
remove pinion nut and washer.
(11) Remove
companion
flange
with
Remover
C-452 (Fig. 21).
(12) Remove pinion seal with pry tool or slide-
hammer mounted screw.
INSTALLATION
NOTE: The outer perimeter of the seal is pre-coated
with a special sealant.
(1) Apply a light coating of gear lubricant on the
lip of pinion seal.
(2) Install new pinion seal with Installer C-3860-A
and Handle C-4171 (Fig. 22)
(3) Install companion flange on the end of the
shaft with the reference marks aligned.
(4) Install bolts into two of the threaded holes in
the companion flange, 180° apart.
(5) Position Holder 6719 against the companion
flange and install a bolt and washer into one of the
remaining threaded holes. Tighten the bolts so holder
is held to the flange.
(6) Install companion flange on pinion shaft with
Installer C-3718 and Holder 6719.
(7) Install pinion washer and a new pinion nut.
The convex side of the washer must face outward.

CAUTION: Do not exceed the minimum tightening
torque when installing the companion flange retain-
ing nut at this point. Damage to collapsible spacer
or bearings may result.
(8) Hold companion flange with Holder 6719 and
tighten the pinion nut to 285 N·m (210 ft. lbs.) (Fig.
23). Rotate pinion several revolutions to ensure the
bearing rollers are seated.
(9) Rotatepinion
using
an
inch
pound
torque
wrench. Rotating torque should be equal to the read-
ing recorded during removal plus an additional 0.56
N·m (5 in. lbs.) (Fig. 24).

CAUTION: Never loosen pinion nut to decrease pin-
ion bearing rotating torque and never exceed spec-
ified preload torque. If rotating torque is exceeded,
a new collapsible spacer must be installed.
(10) If rotating torque is low, use Holder 6719 to
hold the companion flange (Fig. 23) and tighten pin-
ion nut in 6.8 N·m (5 ft. lbs.) increments until proper
rotating torque is achieved.
NOTE: The bearing rotating torque should be con-
stant during a complete revolution of the pinion. If
the rotating torque varies, this indicates a binding
condition.
NOTE: The seal replacement is unacceptable if the
final pinion nut torque is less than 285 N·m (210 ft.
lbs.).
(11) Install propeller shaft with the installation
reference marks aligned.
(12) Tighten the companion flange bolts to 108
N·m (80 ft. lbs.).
(13) Install the brake drums.
(14) Install wheel and tire assemblies and lower
the vehicle.
(15) Check the differential housing lubricant level.
DIFFERENTIAL
REMOVAL
(1) Raise and support vehicle.
(2) Remove filler plug from the differential cover.
(3) Remove the differential cover and drain the
lubricant.
(4) Clean the housing cavity with a flushing oil,
light engine oil or lint free cloth. Do not use water,
steam, kerosene, or gasoline for cleaning.
(5) Remove the axle shafts.
(6) Remove RWAL/ABS sensor from housing.
NOTE: Side play resulting from bearing races being
loose on case hubs requires replacement of the dif-
ferential case.
(7) Mark the differential housing and differential
bearing caps for installation reference (Fig. 25).
(8) Remove bearing threaded adjuster lock from
each bearing cap.
(9) Loosen differential bearing cap bolts.
(10) Loosen differential bearing adjusters through
the axle tubes with Wrench C-4164 (Fig. 26).
(11) Hold the differential case while removing
bearing caps and adjusters.
(12) Remove the differential case.
NOTE:
Tag
the
differential
bearing
cups
and
threaded adjusters to indicate their location.
DISASSEMBLY
(1) Remove pinion shaft lock screw (Fig. 27).
(2) Remove pinion shaft.
(3) Rotate differential side gears and remove the
differential pinions and thrust washers (Fig. 28).
(4) Remove the differential side gears and thrust
washers.
