(2) Remove large boot clamp which retains inner
tripod joint sealing boot to tripod joint housing and
discard.
(3) Remove small clamp which retains inner tripod
joint sealing boot to interconnecting shaft and dis-
card.
(4) Remove the sealing boot from the tripod hous-
ing and slide it down the interconnecting shaft.

(5) Slide the tripod joint housing off the spider
assembly and the interconnecting shaft (Fig. 11).
(6) Remove snap-ring which retains spider assem-
bly to interconnecting shaft (Fig. 12). Do not hit the
outer tripod bearings in an attempt to remove
spider assembly from interconnecting shaft.
(7) Remove the spider assembly from interconnect-
ing shaft. If spider assembly will not come off inter-
connecting shaft by hand, it can be removed by
tapping spider assembly with a brass drift (Fig. 13).
(8) Slide sealing boot off interconnecting shaft.
(9) 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 half shaft assembly
will require replacement. Component parts of
these half shaft assemblies are not serviceable.
INSTALLATION
(1) Slide inner CV joint seal boot retaining clamp,
onto the interconnecting shaft. Then, slide the
replacement inner CV joint sealing boot onto the
interconnecting shaft. Inner CV joint seal boot
MUST be positioned on interconnecting shaft
so the raised bead on the inside of the small
diameter end of the seal boot is in mating
groove on interconnecting shaft (Fig. 14).

(2) Install spider assembly onto interconnecting
shaft (Fig. 15). Spider assembly must be installed on
interconnecting shaft far enough to fully install spi-
der retaining snap-ring. If the 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. 16). Do not hit the outer tripod
bearings in an attempt to install spider assem-
bly on interconnecting shaft.
(3) Install the spider assembly to interconnecting
shaft retaining snap-ring into groove on end of inter-
connecting shaft (Fig. 17). 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. 18).
(6) Install inner CV joint seal boot to interconnect-
ing shaft clamp evenly on sealing boot.
(7) Place crimping tool C-4975-A over bridge of
clamp (Fig. 19).

(8) Tighten nut on crimping tool C-4975-A until
jaws on tool are closed completely together, face to
face (Fig. 20).
CAUTION: Seal boot must not be dimpled, stretched
or out of shape in any way. If seal boot is NOT
shaped correctly, equalize pressure in seal and
shape it by hand.
(9) Position sealing boot into the tripod housing
retaining groove. Install seal boot retaining clamp
evenly on sealing boot.
(10) Position trilobal boot to interface with the tri-
pod housing. The lobes of the boot must be properly
aligned with the recess’s of the tripod housing.
CAUTION:
The
following
positioning
procedure
determines the correct air pressure inside the inner
CV joint assembly prior to clamping the sealing
boot to inner CV joint housing. If this procedure is
not done prior to clamping sealing boot to CV joint
housing sealing boot durability can be adversely
affected.
CAUTION: When venting the inner CV joint assem-
bly, use care so that the inner CV sealing boot does
not get punctured, or in any other way damaged. If
sealing boot is punctured, or damaged in any way
while being vented, the sealing boot can not be
used.
(11) Insert a trim stick between the CV joint hous-
ing and the sealing boot insert to vent inner CV joint
assembly (Fig. 21). When inserting trim stick
between
tripod
housing
and
sealing
boot
ensure trim stick is held flat and firmly against
the tripod housing. If this is not done damage
to the sealing boot can occur.
(12) With trim stick inserted between sealing boot
insert and the CV joint housing, position the inter-
connecting shaft so it is at the center of its travel in
the tripod joint housing. Remove the trim stick from
between the sealing boot insert and the CV joint
housing. This procedure will equalize the air
pressure in the CV joint, preventing premature
sealing boot failure.
