INSTALLATION
(1) Pack the bearing caps 1/3 full of wheel bearing
lubricant. Apply extreme pressure (EP), lithium-base
lubricant to aid in installation.
(2) Position the spider in the yoke. Insert the seals
and bearings, then tap bearing caps into the yoke
bores far enough to hold the spider in position.
(3) Place the socket (driver) against one bearing
cap. Position the yoke with the socket in a vise.
(4) Tighten the vise to force the bearing caps into
the yoke. Force the caps enough to install the retain-
ing clips.
(5) Install the bearing cap retaining clips.
(6) Install axle shaft.
PINION SEAL
REMOVAL
(1) Raise and support the vehicle.
(2) Remove wheel and tire assemblies.
(3) Remove brake rotors and calipers, refer to 5
Brakes for procedures.
(4) Mark propeller shaft and pinion companion
flange for installation reference.
(5) Remove the propeller shaft from the pinion
companion flange.
(6) Rotate the pinion gear a minimum of ten times
and verify the pinion rotates smoothly.
(7) Record torque necessary to rotate the pinion
gear with a inch pound torque wrench.
(8) Using a short piece of pipe and Spanner
Wrench 6958 to hold the pinion companion flange
and remove the pinion nut and washer.
(9) Remove pinion companion flange with Remover
C-452 and Flange Wrench C-3281.
(10) Remove pinion seal with Remover 7794-A and
a slide hammer (Fig. 31).
INSTALLATION
(1) Apply a light coating of gear lubricant on the
lip of pinion seal. Install seal with an appropriate
installer (Fig. 32).
(2) Install pinion companion flange on the pinion
gear with Installer W-162-D, Cup 8109 and Wrench
6958.
CAUTION: Never exceed the minimum tightening
torque 298 N´m (220 ft. lbs.) while installing pinion
nut at this point. Damage to collapsible spacer or
bearings may result.
(3) Install the pinion washer and anewnut on
the pinion gear.Tighten the nut only enough to
remove the shaft end play.
