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

junction block. A label on the underside of the PDC
cover identifies the locations of the ABS fuses.
(2) Inspect the 25-way electrical connector at the
CAB for damaged, spread, or backed-out wiring ter-
minals. Verify that the 25-way connector is fully
inserted in the socket of the CAB. Be sure that wires
are not stretched tight or pulled out of the connector.
(3) Verify that all the wheel speed sensor connec-
tions are secure.
(4) Look for poor mating of connector halves or ter-
minals not fully seated in the connector body.
(5)
Check for improperly formed or damaged termi-
nals. All connector terminals in a suspect circuit should
be carefully reformed to increase contact tension.
(6) Look for poor terminal-to-wire connections.
This requires removing the terminal from the connec-
tor body to inspect it.
(7) Verify pin presence in the connector assembly
(8) Check for proper ground connections. Check all
ground connections for signs of corrosion, loose fas-
teners, or other potential defects. Refer to the wiring
diagrams for ground locations.
(9) Look for problems with the main power sources
of the vehicle. Inspect the battery, generator, ignition
circuits and other related relays and fuses.
If a visual check does not find the cause of the
problem, operate the car in an attempt to duplicate
the condition and record any trouble codes.
Most failures of the ABS disable the ABS function
for the entire ignition cycle even if the fault clears
before key-off. There are some failure conditions,
however, that allow ABS operation to resume during
the ignition cycle in which the trouble occurred even
if the trouble conditions are no longer present.
The following trouble conditions may result in
intermittent illumination of the amber ABS warning
lamp.
²Low system voltage. If Low System Voltage is
detected by the CAB, the CAB will turn on the ABS
Warning Lamp until normal system voltage is
achieved. Once normal voltage is seen at the CAB,
normal operation resumes.
²High system voltage. If high system voltage is
detected by the CAB, the CAB will turn on the
Amber ABS Warning Lamp until normal system volt-
age is achieved. Once normal voltage is again
detected by the CAB, normal ABS operation resumes.
Additional possible causes that may result in the
illumination of the amber ABS warning lamp are as
follows:
²Any condition that interrupts electrical current
to the CAB may cause the amber ABS warning lamp
to turn on intermittently.
²If PCI communication between the body control-
ler and the CAB is interrupted, the body controller
can turn on the amber ABS warning lamp.
TONE WHEEL
Tone wheels can cause erratic wheel speed sensor
signals. Inspect tone wheels for the following possible
causes:
²missing, chipped, or broken teeth
²contact with the wheel speed sensor
²wheel speed sensor to tone wheel alignment
²wheel speed sensor to tone wheel clearance
²excessive tone wheel runout
²tone wheel loose on its mounting surface
If a front tone wheel is found to need replacement,
the drive shaft must be replaced. No attempt should
be made to replace just the tone wheel. Refer to the
DIFFERENTIAL AND DRIVELINE group in this
service manual for removal and installation.
If a rear tone wheel is found to need replacement,
the rear hub and bearing must be replaced. No
attempt should be made to replace just the tone
wheel. Refer to the SUSPENSION group in this ser-
vice manual for removal and installation.
If wheel speed sensor to tone wheel contact is evi-
dent, determine the cause and correct it before
replacing the wheel speed sensor or tone wheel.
Check the gap between the speed sensor head and
the tone wheel to ensure it is within specifications.
Refer to SPECIFICATIONS in this section of the ser-
vice manual for the minimum and maximum wheel
speed sensor to tone wheel clearance.
Excessive wheel speed sensor runout can cause
erratic wheel speed sensor signals. Refer to SPECI-
FICATIONS in this section of the service manual for
the maximum allowed tone wheel runout. If tone
wheel runout is excessive, determine if it is caused
by a defect in the driveshaft assembly or hub and
bearing. Replace as necessary.
Tone wheels are pressed onto their mounting sur-
faces and should not rotate independently from the
mounting surface. Replacement of the front drive-
shaft or rear hub and bearing is necessary.
BRAKE FLUID CONTAMINATION
Indications of fluid contamination are swollen or
deteriorated rubber parts. Swelling indicates the
presence of petroleum in the brake fluid.
To test for contamination, put a small amount of
drained brake fluid in clear glass jar. If the fluid sep-
arates into layers, there is mineral oil or other fluid
contamination of the brake fluid.
If the brake fluid is contaminated, drain and thor-
oughly flush the brake system. Replace all the rubber
parts or components containing rubber coming into
contact with the brake fluid including: the master
cylinder; proportioning valves; caliper seals; wheel
cylinder seals; ABS hydraulic control unit; and all
hydraulic fluid hoses.
