GENERAL INFORMATION
FRONT DRIVESHAFTS
Vehicles equipped with either an automatic or
manual transmission use the unequal–length driveshaft system.
Vehicles equipped with automatic transaxles use a
solid short interconnecting shaft on the left side. The
right side of the vehicle uses a longer solid interconnecting shaft (Fig. 1).
Vehicles equipped with manual transaxles use a
larger diameter (32 mm) short interconnecting shaft
on the left side. The right side uses a longer interconnecting damper (Fig. 1).

SPECIAL TOOLS
DRIVESHAFT .......................... 16
Driveshafts used on both the right and left sides of
the vehicle use a tuned rubber damper weight. The
damper weight applications vary by which side of the
vehicle the driveshaft is located on and the transmission application of the vehicle. When replacing a
driveshaft, be sure the replacement driveshaft has
the same damper weight as the original.
Both driveshaft assemblies use the same type of
inner and outer joints. The inner joint of both driveshaft assemblies is a tripod joint, and the outer joint
of both driveshaft assemblies is a Rzeppa joint. Both
tripod joints and Rzeppa joints are true constant
velocity (C/V) joint assemblies. The inner tripod joint
allows for the changes in driveshaft length through

the jounce and rebound travel of the front suspension.
On vehicles equipped with ABS brakes, the outer
C/V joint is equipped with a tone wheel used to
determine vehicle speed for ABS brake operation.
The inner tripod joint of both driveshafts is splined
into the transaxle side gears. The inner tripod joints
are retained in the side gears of the transaxle using
a snap ring located in the stub shaft of the tripod
joint. The outer C/V joint has a stub shaft that is
splined into the wheel hub and retained by a hub nut
using a nut lock and cotter pin.
NOTE: This vehicle does not use a rubber–lip bearing seal as on previous front–wheel–drive cars to
prevent contamination of the front wheel bearing.
On these vehicles, the face of the outer C/V joint
fits deeply into the steering knuckle, using a close
outer C/V joint–to–steering knuckle fit. This design
deters direct water splash on bearing seal while
allowing any water that gets in, to run out the bottom of the steering knuckle bearing bore. It is
important to thoroughly clean the outer C/V joint
and the wheel bearing area in the steering knuckle
before it is assembled after servicing.
FRONT DRIVESHAFT IDENTIFICATION
Driveshafts and driveshaft inner and outer boots
can be identified as shown in (Fig. 2). Driveshaft boot
location on the driveshaft assemblies is determined
by the number of convolutions on the driveshaft boot.
Refer to (Fig. 2) for the correct location of the sealing
boots.
DIAGNOSIS AND TESTING
DRIVESHAFT DIAGNOSIS
VEHICLE INSPECTION
(1) Check for grease in the vicinity of the inboard
tripod joint and outboard C/V joint; this is a sign of
inner or outer joint seal boot or seal boot clamp damage.
(2) A light film of grease may appear on the right
inner tripod joint seal boot; this is considered normal
and should not require replacement of the seal boot.
The right inner tripod joint seal boot is made of silicone rubber; which will allow the weeping (sweating)
of the joint lubricant to pass through it while in operation.

PL DIFFERENTIAL AND DRIVELINE 3 - 3
DIAGNOSIS AND TESTING (Continued)
NOISE AND/OR VIBRATION IN TURNS
A clicking noise and/or a vibration in turns could
be caused by one of the following conditions.
(1) Damaged outer C/V or inner tripod joint seal
boot or seal boot clamps. This will result in the loss
and/or contamination of the joint grease, resulting in
inadequate lubrication of the joint.
(2) Noise may also be caused by another component of the vehicle coming in contact with the driveshafts.
CLUNKING NOISE DURING ACCELERATION
This noise may be a result of one of the following
conditions:
(1) A torn seal boot on the inner or outer joint of
the driveshaft assembly.
(2) A loose or missing clamp on the inner or outer
joint of the driveshaft assembly.
(3) A damaged or worn driveshaft C/V joint.
SHUDDER OR VIBRATION DURING ACCELERATION
(1) A worn or damaged driveshaft inner tripod
joint.
(2) A sticking tripod joint spider assembly (inner
tripod joint only).
(3) Improper wheel alignment. See Wheel Alignment in this group for alignment checking and setting procedures and specifications.
VIBRATION AT HIGHWAY SPEEDS
(1) Foreign material (mud, etc.) packed on the
backside of the wheel(s).
(2) Out of balance front tires or wheels. See Group
22, Wheels And Tires for the required balancing procedure.
(3) Improper tire and/or wheel runout. See Group
22, Wheels And Tires for the required runout checking procedure.
REMOVAL
CAUTION: The driveshaft, when installed, acts as a
bolt and secures the front hub/bearing assembly. If
vehicle is to be supported or moved on its wheels
with a driveshaft removed, install a PROPER–SIZED
BOLT AND NUT through front hub. Tighten bolt and
nut to 183 N·m (135 ft. lbs.). This will ensure that
the hub bearing cannot loosen.
(1) Remove cotter pin, nut lock, and spring washer
(Fig. 3) from the end of the outer C/V joint stub axle.
Fig. 3 Cotter Pin, Nut Lock and Spring Washer
(2) Loosen (but do not remove) stub axle–to–hub/
bearing retaining nut (Fig. 4). Loosen hub nut while
vehicle is on the floor with the brakes applied. The
front hub and driveshaft are splined together and
retained by the hub nut.
REMOVAL AND INSTALLATION
FRONT DRIVESHAFTS
CAUTION: Boot sealing is vital to retain special
lubricants and to prevent foreign contaminants
from entering the C/V joint. Mishandling, such as
allowing the assemblies to dangle unsupported, or
pulling or pushing the ends can cut boots or damage C/V joints. During removal and installation procedures, always support both ends of the driveshaft
to prevent damage.

INNER TRIPOD JOINT SEAL BOOT
REMOVAL
To remove sealing boot from driveshaft for replacement, the driveshaft assembly must be removed from
the vehicle. See Servicing Driveshaft in this section
for the required driveshaft removal and replacement
procedure.
The inner tripod joints use no internal retention in
the tripod housing to keep the spider assembly in the
housing. Therefore, do not pull on the interconnecting shaft to disengage tripod housing from transmission stub shaft. Removal in this manner will cause
Fig. 23 Front Hub To Stub Shaft Nut Installed
damage to the inboard joint sealing boots.
(1) Remove the driveshaft requiring boot replacement from the vehicle. See Servicing Driveshaft in
this section for the required driveshaft removal procedure.
(2) Remove large boot clamp that retains inner tripod joint sealing boot to tripod joint housing (Fig. 26)
and discard. Then remove small clamp that retains
inner tripod joint sealing boot to interconnecting
shaft and discard. Remove the sealing boot from the
tripod housing and slide it down the interconnecting
shaft.

DISASSEMBLY AND ASSEMBLY
DRIVESHAFT RECONDITION
NOTE: The only service that is to be performed on
the driveshaft assemblies is the replacement of the
driveshaft seal boots.
If any failure of internal driveshaft components is
diagnosed during a vehicle road test or disassembly
of the driveshaft, the driveshaft will need to be
replaced as an assembly.
NOTE: Lubricant requirements and quantities are
different for inner joints than for outer joints. Use
only the recommended lubricants in the required
quantities when servicing driveshaft assemblies.
CAUTION: When removing the spider joint from the
tripod joint housing, hold the rollers in place on the
spider trunions to prevent the rollers and needle
bearings from falling away.
(3) Slide the interconnecting shaft and spider
assembly out of the tripod joint housing (Fig. 27).
(4) Remove snap ring that retains spider assembly
to interconnecting shaft (Fig. 28). Remove the spider
assembly from interconnecting shaft. If spider assembly will not come off interconnecting shaft by hand, it
can be removed by tapping spider assembly with a
brass drift (Fig. 29). Do not hit the outer tripod
bearings in an attempt to remove spider assembly from interconnecting shaft.
(5) Slide sealing boot off interconnecting shaft.
(6) Thoroughly clean and inspect spider assembly,
tripod joint housing, and interconnecting shaft for
any signs of excessive wear. If any parts show
signs of excessive wear, the driveshaft assembly
will require replacement. Component parts of
these driveshaft assemblies are not serviceable.
