REMOVAL AND INSTALLATION
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 dam-
age C/V joints. During removal and installation pro-
cedures, always support both ends of the driveshaft
to prevent damage.
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 203 N´m (150 ft. lbs.). This will ensure that
the hub bearing cannot loosen.
(1) Disconnect battery negative cable.
(2) Place transaxle in gated park.
(3) Raise vehicle on hoist.
(4) Remove wheel and tire assembly (Fig. 3).(5) Remove the driveshaft to hub and bearing
retaining nut (Fig. 4).
(6) If equipped with ABS, disconnect the front
wheel speed sensor and secure harness out of the
way.

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.
See (Fig. 17) for the exploded view of the front
driveshaft components.
INNER TRIPOD JOINT SEAL BOOT
REMOVAL
To remove sealing boot from driveshaft for replace-
ment, the driveshaft assembly must be removed from
the vehicle. See Driveshaft Removal and Installation
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 interconnect-
ing shaft to disengage tripod housing from transmis-
sion stub shaft. Removal in this manner will cause
damage to the inboard joint sealing boots.
(1) Remove the driveshaft requiring boot replace-
ment from the vehicle. See Driveshaft Removal and
Installation in this section for the required driveshaft
removal procedure.
(2) Remove large boot clamp that retains inner tri-
pod joint sealing boot to tripod joint housing (Fig. 18)
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.

INSTALLATION
NOTE: The inner tripod joint sealing boots are
made from two different types of material. High±
temperature applications use silicone rubber
whereas standard temperature applications use
Hytrel plastic. The silicone sealing boots are soft
and pliable. The Hytrel sealing boots are stiff and
rigid. The replacement sealing boot MUST BE the
same type of material as the sealing boot that was
removed.
(1) Slide inner tripod joint seal boot retaining
clamp, onto interconnecting shaft. Then slide the
replacement inner tripod joint sealing boot onto
interconnecting shaft.Inner tripod joint seal boot
MUST be positioned on interconnecting shaft,
so the raised bead on the inside of the seal boot
is in groove on interconnecting shaft (Fig. 22).
(2) Install spider assembly onto interconnecting
shaft with chamfer on spider assembly toward inter-
connecting shaft (Fig. 23). Spider assembly must be
installed on interconnecting shaft far enough to fully
install spider retaining snap ring. If spider assembly
will not fully install on interconnecting shaft by
hand, it can be installed by tapping the spider body
with a brass drift (Fig. 24).Do not hit the outer
tripod bearings in an attempt to install spider
assembly on interconnecting shaft.
(3) Install the spider assembly to interconnecting
shaft retaining snap ring into groove on end of inter-
connecting shaft (Fig. 25). Be sure the snap ring is
fully seated into groove on interconnecting shaft.(4) Distribute 1/2 the amount of grease provided in
the seal boot service package (DO NOT USE ANY
OTHER TYPE OF GREASE) into tripod housing. Put
the remaining amount into the sealing boot.
(5) Align tripod housing with spider assembly and
then slide tripod housing over spider assembly and
interconnecting shaft (Fig. 26).
(6) Install inner tripod joint seal boot to intercon-
necting shaft clamp evenly on sealing boot.

CAUTION: When venting the inner tripod joint
assembly, use care so inner tripod sealing boot
does not get punctured or, in any other way, dam-
aged. If sealing boot is punctured or damaged while
being vented, the sealing boot can not be used.
(9) Insert a trim stick between the tripod joint and
the sealing boot to vent inner tripod joint assembly
(Fig. 29).When inserting trim stick between tri-
pod housing and sealing boot, ensure trim stick
is held flat and firmly against the tripod hous-
ing. If this is not done, damage to the sealing
boot can occur.If inner tripod joint has a Hytrel
(hard plastic) sealing boot, be sure trim stick is
inserted between soft rubber insert and tripod hous-
ing, and not the hard plastic sealing boot and soft
rubber insert.
(10) With trim stick inserted between sealing boot
and tripod joint housing, position inner tripod joint
on driveshaft until correct sealing boot edge to edge
length is obtained for type of sealing boot material
being used (Fig. 30) (Fig. 31). Then remove the trim
stick.
(11) Clamp tripod joint sealing boot to tripod joint
using required procedure for type of boot clamp
application. If seal boot uses crimp type boot clamp,
clamp sealing boot onto tripod housing using crimper,
Special Tool C-4975-A. Place crimping tool C-4975-A
over bridge of clamp (Fig. 32). Tighten nut on crimp-
ing tool C-4975-A until jaws on tool are closed com-
pletely together, face±to±face (Fig. 33).(12) If seal boot uses low profile latching type boot
clamp, clamp sealing boot onto tripod housing using
clamp locking tool, Snap-OntYA3050 (or an equiva-
lent). Place prongs of clamp locking tool in the holes
of the clamp (Fig. 34). Squeeze tool together until top
band of clamp is latched behind the two tabs on
