Driveshaft
- Road test vehicle to check for noise or vibration
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.

NOTE-
Boltgrade is marked on the bolt head. When replacing bolts,
only use bolts of the same strength and hardness as the orig-
inals installed.
Flex-disc, replacing
- Checlc flex-disc between front section of driveshafl and trans-
mission output flange for craclts, tears, missing pieces, or
distortion. Check for worn bolt hole bores in flange.
- If flex-disc needs replacement, remove driveshafl as de-
scribed earlier.
- Unbolt flex-disc from driveshaft.
NOTE-
Removal andinstallation of the bolts may be made easier by
placing a large hose clamp around the flex-disc, and tighten-
ing the clamp slightly to compress the rubber.

Install new flex-disc using new self-locking nuts. Molded ar-
rows (arrows) on coupling should point towards flange arms.

Center bearing assembly, replacing
The center bearing assembly consists of a grooved ball bear-
ing in a rubber mount. The bearing assembly is pressed
the driveshaft.
- Remove driveshaft. See Driveshaft, removing
- Matchmark front and rear driveshaft sections before
separating.
Remove bolt (arrow) securing front and rear halves of
driveshaft and pull driveshaft apart.
- Remove shim and dust shield, where fitted
- Use puller to remove center bearing assembly from
driveshaft. onto

- 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.

- 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.

Slide strut assembly out of steering lknucltle pinch collar. If
necessary use pry bar.
CA UTIOI\C
Do notpullstrut out of steering knuckle with twisting motion.
This can scratch and damage the strut.
Disassemble and reassemble strut assembly as described
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.
When attaching stabilizer
lrnk to strut, use a thin wrench to
counterhold
link ball joint while t~ghtening nut.
- Have car professionally al~gned when job IS complete.
