REMOVAL
(1) Raise and support the vehicle.
(2) Scribe a mark on the universal joint, compan-
ion flange, and pinion shaft for installation reference.
(3) Disconnect the propeller shaft from the com-
panion flange. Secure the propeller shaft in an
upright position to prevent damage to the rear uni-
versal 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 a (in. lbs.) dial-type 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 6719 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 6719. Remove the
pinion nut and washer.
(11) Remove the companion flange with Remover
C-452 (Fig. 15).
(12) Remove the pinion seal with suitable pry tool
or slide-hammer mounted screw.

INSTALLATION
(1) Clean the seal contact surface in the housing
bore.
(2) Examine the splines on the pinion shaft for
burrs or wear. Remove any burrs and clean the shaft.
(3) Inspect companion flange for cracks, worn
splines and worn seal contact surface. Replace com-
panion flange if necessary.
NOTE: The outer perimeter of the seal is pre-coated
with a special sealant. An additional application of
sealant is not required.
(4) Apply a light coating of gear lubricant on the
lip of pinion seal.
(5) Install the new pinion seal with Installer
C-4076-B and Handle C-4735-1 for 8 1/4 axles (Fig.
16) and Installer C-3860-A and Handle C-4171 for 9
1/4 axles.
NOTE: The seal is correctly installed when the seal
flange contacts the face of the differential housing.
(6) Position the companion flange on the end of the
shaft with the reference marks aligned.
(7) Install socket head bolts into two of the
threaded holes in the companion flange, 180° apart.
(8) Position Holder 6719 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.
