Typical universal joint assembly
joints are removed from the car, they should
be checked and regreased.
1. Remove the joints from the driveshaft.
These can sometimes be tapped out, but
stubborn joints must be pressed out.
2. Remove the bearing cups and seals,
being careful not to lose any rollers.
3. Inspect the cups and trunnion ends for
damage or wear. Ensure that all bearing roll

REMOVAL AND INSTALLATION
1979 and Earlier Models
1. Jack the rear of the car up and support
with jackstands.
2. Disconnect the inside trunnion from the
carrier yoke.
3. On the outer end, bend down the lock-
tabs and wire-brush the bolts.
4. Scratch a mark on the camber adjusting
cam and the bracket to permit realignment.
5. Loosen the camber adjustment nut and
turn the cam so that the eccentric end points
inward. Doing this will push the trailing arm
out and give more room for driveshaft re
moval.
6. Remove the driveshaft, outside end first.
7. To install, position the inside end of the
driveshaft in the carrier yoke and asemble U-
bolts or clamp and bolts. Torque the bolts to
14-18 ft. Ibs.
NOTE:
When removing and installing both
axle driveshafts, be certain to position the
carrier side yokes so that the trunnion seats
are at 90° angles to each other.
8. Install the outside end of the driveshaft
into the spindle drive flange. Install the locks
and bolts. Torque the bolts to 70-90 ft. Ibs.
and bend the locktabs up.

port it safely with jacks tands.
2. Disconnect the inboard driveshaft
trunnion from the side gear yoke. Remove the
plastic shield.
3. Disconnect the shaft flange from the
spindle drive flange.

mounting bracket so that their relationship
will be properly maintained during assem
bly.
5. Loosen the camber adjusting nut. Ro
tate the adjusting cam so that the high point
of the cam faces inward, which pushes the
control arm outward. This will provide addi
tional working clearance.
6. Remove the driveshaft, outboard end
first. Install the driveshaft in the following
manner:
7. Place the inboard driveshaft trunnion
into the side gear yokes. For vehicles using
U-bolts with 1.06" dia. bearing caps, torque
the bolts to 15 ft. Ibs; for U-joints with 1.13"
dia. bearing caps, torque the bolts to 25 ft.
Ibs.
8. Rotate the yokes so that the trunnion
seats are phased 90° apart.
9. Attach the outboard end of the drive-
shaft in the same manner as step 7.
10. Install the plastic shield. Align the
