This repair group covers repair and replacement of the
driveshaft and driveshaft components.
Driveshaft repairs consist of replacement of front flex-disc.
center mount or rear
CV joint. If the driveshaft joint is defec-
tive, replace the complete driveshaft.
Drive axle repairs are covered in
331 Final Drive

Driveshaft, installing
- Prepare CV joint for reinstallation:
Extend joint to limit.
Clean off old grease and fill with fresh grease
Install new seal.
- Bend driveshaft slightly at center universal joint to install
CAUTION-
Do not allow CVjoint seal to become displaced.
- Align matchmarlts on driveshaft to matchmarks on final drive
and transmission flanges.
- Fit constant velocity joint to final drive input flange. Alternate-
ly tighten two opposite nuts to draw constant velocity joint
evenly into the final drive input flange. Once seated, tighten
down remaining nuts.
I CAUTION-
I Do not reuse self-locking nuts. These nuts are designed to be /
I used onlv once. 1
- Insert bolts in front of driveshafl to transmission output
flange. Counterhold each bolt while tightening nut.
CAUTION-
. Do not reuse self-locking nuts. These nuts are designed to
be used only once.
Avoid stressing the flex-disc when torquing the bolts.
Do this by counterholding the bolts and turning the nuts
on the flange side.
- Position center support bearing and install mounting nuts.
Use new self-locking nuts.
- Install heat shields.
- Install rear transmission support crossmember.
- Install exhaust system. See 180 Exhaust System.
Reconnect oxygen sensor wiring harnesses and reattach
wiring harness retainers to rear transmission support
crossrnernber.

- On installation, drive new center bearing firmly to stop.
Reassemble driveshaft using matchmarks made prior to
disassembly.
- Clean threads and install bolt securing driveshaft halves.
Use thread locking compound
LoctiteO or equivalent.
Tightening torque Driveshaft front half to rear half
(use thread locking compound) 97
Nm (72 fl-lb)
- Install driveshaft as described earlier.
Front centering guide, replacing
The front centering guide centers the driveshafl in relation to
the transmission. The guide is press-fit into a cavity in the
front of the driveshafl and slides onto the transmission output
shaft.
No specifications are given
forwear of the guide, but general-
ly the guide should fit snugly on the transmission output shafl.
NOTE-
Some driveshafts have a dust cap installed on the end of the
driveshaft, over the centering guide. The dust cap may be-
come bent or distorted when the driveshaft is removed or
in-
stalled. Damage to the dust cap should not affect the
centering guide and should not be mistaken for guide wear.
- Remove driveshafl as described earlier
- Pack cavity behind centering guide with heavy grease until
grease is flush with bottom edge of guide.
- Insert 14 mm (approximately 9/16 in.) diameter mandrel or
metal rod into guide. Strike guide with hammer to force cen-
tering guide out.
NOTE-
Tlie mandrel should fit snugly in the centering guide so that
the grease cannot escape around the sides of the mandrel.
- Remove old grease from driveshaft, lubricate new centering
guide with molybdenum disulfide grease
(MolykoteO, Long-
term8 2 or equivalent) and drive it into driveshaft.
4 When installing new driveshafl centering guide, be sure seal-
ing lip of guide faces outward. Drive guide into driveshaft to
a protrusion depth of
4 - 6mm (0.16 - 0.24 in.).
- Install driveshaft as described earlier.

later.
When installing new strut, be sure to align locator letter (A)
on strut body with slot in steering
lknuckle pinch collar (6).
Struts are marked with L for left and R for right.
Remainder of installation is reverse of removal.
Make sure strut shoulder (below locator letter) bottoms out
in steering knuckle pinch collar.
Use new self-locking nuts and bolts.

frame through rubber bushings and to the steering ltnuckles
by ball joints.
NOTE-
Tension struts are sometimes called thrust arms or thrust
rods.
Control arms or tension struts are sometimes called lower
front arms or lower rear arms.
Inspect ball joints for wear and looseness. lnspect bushings
for wear or fluid
lealts. The ball joint can only be replaced as
part of an entire suspension arm assembly. Some suspen-
sion arm
bushinas are available as re~lacement Darts. Al-
ways replace in pairs
NOTE-
Steering wheel vibration during braking (usually at road
speeds of
50 to 60 m.p.h.) are often causedby faulty suspen-
sion arm bushings, not out-of-true brake rotors.
Some special tools may be required to remove suspension
arms and to replace bushings. Read procedures through be-
fore beginning the job.

that the car is firmly supported on jack stands de-
signed for the purpose. Place jack stands underneath struc-
tural chassis points. Do not place jack stands under

parfs.
Cars equipped with vertical headlight adjustment system:
Disconnect control arm from level sensor.
Remove control arm fasteners (arrows). Lightly tap inner
control arm mounting bolt out of subframe.
