GENERAL INFORMATION
FRONT DRIVESHAFTS
All LH platform vehicles are equipped with an
unequal length driveshaft system (Fig. 1). The left
side of the vehicle is equipped with a longer drive-
shaft than the right side of the vehicle. The LH plat-
form uses solid interconnecting shafts on both sides
of the vehicle.
The driveshaft assemblies are three piece units.
Each driveshaft has a tripod joint, an interconnecting
shaft and a outer C/V Joint. The tripod joint is
splined onto the transaxle stub shaft, and the outer
C/V joint has a stub shaft that is splined into the
front wheel hub and bearing assembly.
NOTE: The inner tripod joint boots, on the LH plat-
form vehicle are made of silicone rubber. The outer
C/V boots are made of Hytrel plastic. When drive-
shaft boots are replaced be sure boots of the cor-
rect material are used.
The driveshafts used on the LH platform vehicles are
supplied by Delphi-Saginaw for all available drivelines.
DESCRIPTION AND OPERATION
DRIVESHAFT SERVICE
Procedures for removal and installation of drive-
shafts on the LH platform vehicles are different and

somewhat easier, than those on other front wheel
drive vehicles. This new driveshaft design, allows
both driveshafts to be removed from the vehicle with-
out dismantling the transaxle.
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, pulling or
pushing the ends can cut boots or damage C/V
joints. The LH platform driveshafts use no retention
system to retain the spider assembly in the tripod
housing. During removal and installation procedures
always support both ends of the driveshaft to pre-
vent damage or disengaging tripod joint. Therefore,
do not pull on the interconnecting shaft when
attempting to remove drive shafts from vehicle.
DIAGNOSIS AND TESTING
DRIVESHAFT DIAGNOSIS
VEHICLE INSPECTION
(1) Check for grease in the vicinity of the inboard tri-
pod 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 inner
tripod joint seal boot; this is considered normal and
should not require replacement of the seal boot. All
inner tripod joint seal boots are made of silicone rub-
ber; which will allow the weeping (sweating) of the
joint lubricant to pass through it while in operation.
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 compo-
nent of the vehicle coming in contact with the drive-
shafts.
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
This problem could be a result of:
(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 Align-
ment in this group for alignment checking and set-
ting procedures and specifications.
VIBRATION AT HIGHWAY SPEEDS
This problem could be a result of:
(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 pro-
cedure.
(3) Improper tire and/or wheel runout. See Group
22, Wheels And Tires for the required runout check-
ing procedure.
REMOVAL AND INSTALLATION
FRONT DRIVESHAFTS
REMOVAL
(1) Raise vehicle on jackstands or centered on a
frame contact type hoist. Refer to Hoisting, in the
Lubrication and Maintenance section of this manual,
for the required lifting procedure to be used for this
vehicle.
(2) Remove the front wheel and tire assembly from
the vehicle.
(3) Remove the front caliper assembly from the
front steering knuckle assembly (Fig. 2). Refer to
Front Disc Brake Service in the Brake Section of this
service manual for caliper removal procedure.
(4) Remove front braking disk (rotor) from hub, by
pulling it straight off wheel mounting studs (Fig. 3).

DESCRIPTION AND OPERATION (Continued)
(5) Remove the speed sensor cable routing bracket
from the strut assembly (Fig. 4).
(6) Remove the hub and bearing to stub axle
retaining nut (Fig. 5).
(7) Install Puller, Special Tool 6790 on hub and
bearing assembly (Fig. 6), using wheel lug nuts to
secure it in place.
(8) Install a wheel lug nut on wheel stud to protect
the threads on the stud. Install a flat blade pry tool
to keep hub from turning. Using Puller, force the
outer stub axle from the hub and bearing asssembly
(Fig. 7).
(9) Dislodge inner tripod joint from stub shaft
retaining snap ring on transaxle assembly (Fig. 8).
Inner tripod joint is dislodged from stub shaft retain-
ing snap ring, by inserting a pry bar between tran-
saxle case and inner tripod joint and prying on tripod
joint. Only disengage the inner tripod joint from
the retaining snap ring. Do not attempt to
