AXLE BEARINGS (Continued)
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 . Ensure that the bearing
part number is against the installer. Verify that the
bearing in installed straight and the tool fully con-
tacts 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.
PINION SEAL
REMOVAL
(1) Raise and support the vehicle.
(2) Mark the universal joint, companion flange and
pinion shaft for installation reference.
(3) Remove the propeller shaft from the companion
flange. Secure the propeller shaft in an upright posi-
tion to prevent damage to the rear universal joint.
(4) Remove the wheel and tire assemblies.
(5) Remove the brake drums to prevent any drag.
The drag may cause a false bearing preload torque
measurement.
(6) Rotate the companion flange three or four
times.
(7) Measure the amount of torque necessary to
rotate the pinion with an inch pound torque wrench.
Record the torque reading 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
bolts so the holder is held to the flange.
(10) Hold the flange with holder and remove the
pinion nut and washer.
(11) Remove the companion flange with Remover
C-452 (Fig. 22).
(12) Remove pinion seal with a pry tool or slide-
hammer mounted screw.
INSTALLATION
NOTE: The outer perimeter of the seal is pre-coated
with a special sealant. An additional application of
sealant is not required.
(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.

1 - COMPANION FLANGE
2 - PULLER TOOL
NOTE: The seal is correctly installed when the seal
flange contacts the face of the differential housing.
(3) Position the companion flange on the end of the
shaft with the reference marks aligned.
(4) Install socket head bolts into two of the
threaded holes in the companion flange, 180° apart.
(5) Position Holder 6719A against the companion
flange and install a hex head bolt and washer into
one of the remaining threaded holes. Tighten the
bolts so the holder is held to the flange.
(6) Seat companion flange on pinion shaft with
Installer C-3718 and Holder 6719.
(7) Remove the installer and install the 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) Rotate the pinion using an (in. lbs.) 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).
