DISASSEMBLY
Single cardan U-joint components are not service-
able. If defective they must be replaced as a unit.
CAUTION: Clamp only the narrow forged portion of
the yoke in the vise. To avoid distorting the yoke,
do not over tighten the vise jaws.
(1) Remove the bearing cap retaining snap rings
(Fig. 22).
NOTE: Saturate the bearing caps with penetrating
oil prior to removal.
(2) Locate a socket with an inside diameter that is
larger than the bearing cap. Place the socket
(receiver) against the yoke and around the perimeter
of the bearing cap to be removed.
(3) Locate a socket with an outside diameter that
is smaller than the bearing cap. Place the socket
(driver) against the opposite bearing cap.
(4) Position the yoke with the sockets in a vise
(Fig. 23).
(5) Tighten the vise jaws to force the bearing cap
into the larger socket (receiver).
(6) Release the vise jaws. Remove the sockets and
bearing cap that was partially forced out of the yoke.
(7) Repeat the above procedure for the remaining
bearing cap and remove spider from the propeller
shaft yoke.

ASSEMBLY
(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. Tap the 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.
INSTALLATION
(1) Clean axle shaft and apply a thin film of
Mopar Wheel Bearing Grease to the shaft splines
and hub bore.
(2) Install axle shaft through the steering knuckle
and into the differential side gears (Fig. 24).
(3) Install hub bearing in the knuckle.
(4) Install hub bearing bolts and tighten to 202
N´m (149 ft. lbs.).
(5) Install ABS wheel speed sensor, brake rotor
and caliper.
(6) Install axle washer and nut. Tighten axle nut
to 179 N´m (132 ft. lbs.).
(7) Rotate axle several 5 to 10 times to seat the
wheel bearing.
(8) Tighten axle nut to final torque of 356 N´m
(263 ft. lbs.).
(9) Align nut to next cotter pin hole and install
new cotter pin.
AXLE SHAFT SEALS
REMOVAL
(1) Remove hub bearings and axle shafts.
(2) Remove differential from differential housing.
(3) Remove differential bearing adjusters (Fig. 25).
(4) Remove axle seals (Fig. 26) located behind
adjusters with Receiver 8498 and Extractor 6310.
(5) Install Receiver 8498 into the adjuster bore.

(6) Install Extractor Rod 6310 with Extractor Foot
6310-9 through the receiver and the axle seal (Fig.
27).
(7) Install Extractor Plate 6310-2 and Nut 6310-7
on the extractor rod.
(8) Tighten nut on the extractor rod (Fig. 28) and
pull the seal out and into the receiver.INSTALLATION
(1) Install axle seal on Installer Cups 8885-2 and
position cups with seals into the housing.
NOTE: Seal are installed with the axle guide facing
outward.
(2) Install Turnbuckle 8885-1 (Fig. 29) into the
installer cups and expand the turnbuckle until the
seal bottom out in the housing.
(3) Install differential into the axle housing.
(4) Install axle shaft and hub bearings
PINION SEAL
REMOVAL
(1) Mark the propeller shaft and pinion flange for
installation reference.
(2) Remove propeller shaft.
(3) Remove hub bearings and axle shafts.
(4) Rotate pinion gear three or four times.
(5) Measure and record the torque necessary to
rotate (Fig. 30) the pinion gear with an inch pound
torque wrench.

(6) Hold pinion flange with Flange Wrench 8979
(Fig. 31) and remove pinion flange nut and washer.
(7) Remove pinion flange with Pinion Flange
Puller 8992 (Fig. 32).
(8) Remove pinion shaft seal with a pry tool or
slide hammer mounted screw.
INSTALLATION
(1) Installnewpinion seal with Installer 8882 and
Handle C-4171 (Fig. 33).
(2) Apply a light coat of teflon thread sealant to
the pinion flange splines.(3) Lightly tap the pinion flange onto the pinion
until a few threads are showing.
(4) Install flange washer andnewpinion nut.
(5) Hold flange with Flange Wrench 8979 and
tighten pinion nut until pinion end play is taken up.
(6) Rotate pinion several times to seat bearings.
(7) Measure pinion rotating torque with an inch
pound torque wrench and compare it to recorded
measurement. Tighten pinion nut in small incre-
ments, until pinion rotating torque is 0.40-0.57 N´m
(3-5 in. lbs.) greater than recorded measurement.
(8) Rotate pinion several times then verify pinion
rotating torque again.
(9) Install axle shafts and hub bearings.
(10) Install propeller shaft with reference marks
aligned.
