the jounce and rebound travel of the front suspen-
sion.
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 bear-
ing 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 bot-
tom 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.
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 dam-
age.
(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 sili-
cone rubber; which will allow the weeping (sweating)
of the joint lubricant to pass through it while in oper-
ation.
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
(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
(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
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) Remove cotter pin, nut lock, and spring washer
(Fig. 2) from the end of the outer C/V joint stub axle.
(2) Loosen (but do not remove) stub axle±to±hub/
bearing retaining nut (Fig. 3). Loosen hub nut while

BASE BRAKE SYSTEM DESCRIPTION
Typical brake equipment consists of:
²Double pin floating caliper disc front brakes.
²Rear automatic adjusting drum brakes.
²Brake Fluid Level Switch.
²Master cylinder.
²Vacuum power booster.
²Double pin floating caliper rear disc brakes are
available on some models.
²Hand operated auto adjust park brake lever.
²Front disc brake pads are semi-metallic.
Vehicles equipped with the optional antilock brake
system (ABS) use a system designated Mark 20 and
is supplied by Teves. This system shares the base
brake hardware with vehicles not equipped withABS. A vehicle equipped with ABS does however use
a different vacuum booster, master cylinder and
brake tubes. Also included in the ABS system is an
integrated control unit (ICU), four wheel speed sen-
sors, and an electronic controller referred to as the
controller antilock brakes (CAB). These components
will be described in detail in the Teves Mark 20 ABS
brake section in this group of the service manual.
The hydraulic brake system is diagonally split on
both the Non-ABS and ABS braking system. With the
left front and right rear brakes on one hydraulic sys-
tem and the right front and left rear on the other.
The master cylinder is anodized, lightweight alu-
minum. On vehicles equipped with front disc brakes
and rear drum brakes, the master cylinder bore is
21.0 mm. On vehicles equipped with four wheel disc
brakes, the master cylinder bore is 22.2 mm.

DESCRIPTION AND OPERATION
FRONT DISC BRAKES
The front disc brakes (Fig. 1) and (Fig. 2) consists
of the following components:
²The driving hub
²Braking disc (rotor)
²Caliper assembly - single piston, floating type
²Brake shoes and linings
The double pin calipers are mounted directly to the
steering knuckles and use no adapter. The caliper ismounted to the steering knuckle using bushings,
sleeves and 2 guide pin bolts which thread directly
into bosses on the steering knuckle (Fig. 2) and (Fig.
3).
Two machined abutments on the steering knuckle
position the caliper. The guide pin bolts, sleeves and
bushings control the side to side movement of the
caliper. The piston seal is designed to pull the piston
back into the bore of the caliper when the brake
pedal is released. This maintains the proper brake
shoe to rotor clearance (Fig. 4).
5 - 2 BRAKESPL

All the front brake forces generated during braking
of the vehicle is taken up directly by the steering
knuckles of the vehicle.
The caliper is a one piece casting with the inboard
side containing a single piston cylinder bore.
The front disc brake caliper piston (Fig. 2), is man-
ufactured from a phenolic compound. The outside
diameter of the caliper piston is 54 mm.
A square cut rubber piston seal is located in a
machined groove in the caliper cylinder bore. This
provides a hydraulic seal between the piston and the
cylinder wall (Fig. 4).
A rubber dust boot is installed in the cylinder bore
opening and in a groove in the piston (Fig. 4). This
prevents contamination in the bore area.As front disc brake linings wear, master cylinder
reservoir brake fluid level will drop. Fluid level
should be checked after replacing linings.
Front disc brakes are equipped with an audible
wear indicator (Fig. 2) on the outboard brake pad.
This sensor emits a sound when the brake lining
may need inspection and/or replacement.
