GENERAL INFORMATION
FRONT DRIVESHAFTS
Vehicles equipped with either an automatic or
manual transmission use the unequal±length drive-
shaft system.
Vehicles equipped with automatic transaxles use a
solid short interconnecting shaft on the left side. The
right side of the vehicle uses a longer solid intercon-
necting shaft (Fig. 1).
Vehicles equipped with manual transaxles use a
larger diameter (32 mm) short interconnecting shaft
on the left side. The right side uses a longer inter-
connecting damper (Fig. 1).Driveshafts used on both the right and left sides of
the vehicle use a tuned rubber damper weight. The
damper weight applications vary by which side of the
vehicle the driveshaft is located on and the transmis-
sion application of the vehicle. When replacing a
driveshaft, be sure the replacement driveshaft has
the same damper weight as the original.
Both driveshaft assemblies use the same type of
inner and outer joints. The inner joint of both drive-
shaft assemblies is a tripod joint, and the outer joint
of both driveshaft assemblies is a Rzeppa joint. Both
tripod joints and Rzeppa joints are true constant
velocity (C/V) joint assemblies. The inner tripod joint
allows for the changes in driveshaft length through

(9) Insert a trim stick between the tripod joint and
the sealing boot to vent inner tripod joint assembly
(Fig. 33).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. 34) (Fig. 35). 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. 36). Tighten nut on crimp-
ing tool C- 4975-A until jaws on tool are closed com-
pletely together, face±to±face (Fig. 37).
(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. 38). Squeeze tool together until top
band of clamp is latched behind the two tabs on
lower band of clamp (Fig. 39).

(9) Position master cylinder on studs of power
brake unit, aligning push rod on power brake vac-
uum booster with master cylinder push rod.
(10) Install the 2 master cylinder mounting nuts
(Fig. 117) and torque to 28 N´m (250 in. lbs.) torque.
(11) Connect brake tubes to master cylinder pri-
mary and secondary ports (Fig. 115) and (Fig. 116).
Torque all tube nuts to 17 N´m (145 in. lbs.) torque.
(12) Reconnect wiring connector to fluid level sen-
sor.
(13) Adjust stop lamp switch as necessary.
(14) Bleed brake system.
CHASSIS TUBES AND HOSES
Always use Mopar replacement brake hose assem-
blies to ensure quality, correct length and superior
fatigue life. Care should be taken to make sure that
the tube and hose mating surfaces are clean and free
from nicks and burrs.Hose assemblies for each
brake are unique and not interchangeable.
Use new copper seal washers on all connections
using Banjo Bolts and tighten all fittings to their
specified torques.
The flexible front hydraulic brake hose should
always be installed on the vehicle by first attaching
the Banjo connector to the caliper assembly. Then
bolt the intermediate hose bracket to the strut
assembly allowing the bracket to position the hose to
prevent twisting. Attach the hose to brake tubing,
before attaching to front frame rail. Then tighten all
brake line fittings to specified torque.
On vehicles equipped with rear drum brakes,
install rear brake hoses first to wheel cylinders and
rear struts and then attach hose bracket to body. On
vehicles equipped with rear disc brakes, attach brake
hoses to calipers and struts first and then attach
brake hose bracket to body. Following this procedure
will reduce potential for twisting brake during instal-
lation procedure.
Only double wall 4.75mm (3/16 in.) steel brake line
tubing, with Al- Rich/ZN-AL alloy coating should be
used for replacement. Care must be taken when
replacing brake tubing, to be sure the proper bending
and flaring tools and procedures are used to avoid
kinking. Do not route the tubes against sharp edges,
moving components or into hot areas. All tubes
should be properly attached with recommended
retaining clips.
PROPORTIONING VALVE (BASE BRAKES)
CAUTION: Proportioning valves (Fig. 125) should
never be disassembled.
There are two proportioning valve assemblies used
in each vehicle. Due to different thread sizes, each
proportioning valve has a different part number. Dur-ing any service procedures identify the proportioning
valve assemblies by supplier part number and or the
color identification band (Fig. 125).
If premature rear wheel skid occurs on hard brake
application, it could be an indication that a malfunc-
tion has occurred with one of the proportioning
valves.
One proportioning valve controls the right rear
brake, and the other proportioning valve controls the
left rear brake (Fig. 126). Therefore, a road test to
determine which rear brake slides first is essential.
If a malfunctioning proportioning valve is sus-
pected on a vehicle. Refer to Brake Hydraulic System
Control Valves in the Diagnosis And Testing Section
in this group of the service manual for the required
test procedure.
REMOVE
Use the proportioning valve test procedure stated
above to determine which proportioning valve
requires replacement, then replace it using procedure
below.
(1) Disconnect brake tube from proportioning valve
requiring removal from the master cylinder (Fig.
126).
(2) Remove proportioning valve (Fig. 126) from the
master cylinder requiring replacement.
INSTALL
(1) Wet O-ring seal on new proportioning valve
using clean fresh brake fluid.
(2) Install proportioning valve in master cylinder

are in good condition. Replace if they are damaged,
dry, or found to be brittle. Refer to Guide Pin Bush-
ing Service in Disc Brake Caliper Service in this sec-
tion of the service manual.
CALIPER GUIDE PIN BUSHING SERVICE
The double pin caliper uses a sealed for life bush-
ing and sleeve assembly. If required this assembly
can be serviced using the following procedure.
REMOVING CALIPER GUIDE PIN BUSHINGS
(1) Remove caliper from brake rotor (See Brake
Shoe Removal). Hang caliper assembly on a wire
hook away from the brake rotor.
(2) Push out and then pull the steel sleeve from
the inside of the bushing using your fingers as shown
in (Fig. 170).
(3) Using your fingers, collapse one side of the
bushing. Then pull on the opposite side to remove
the bushing from the brake caliper housing (Fig.
171).
INSTALLING CALIPER GUIDE PIN BUSHINGS
(1) Fold the bushing in half lengthwise at the solid
middle section of the bushing (Fig. 172).
(2) Insert the folded bushing into the caliper hous-
ing (Fig. 173).Do not use a sharp object to per-
form this step due to possible damage to the
bushing.(3) Unfold the bushing using your fingers or a
wooden dowel until the bushing is fully seated into
the caliper housing. Flanges should be seated evenly
on both sides of the bushing hole (Fig. 174).
(4) Lubricate the inside surfaces of the bushing
using Mopar, Silicone Dielectric Compound or an
equivalent.

DISASSEMBLY AND ASSEMBLY (Continued)

During any reassembly procedures all pipe fittings
in water jacket, and waterbox require cleaning and
application of thread sealant for entire length of
threads.
ACCESSORY DRIVE BELTS
If the engine is equipped with power steering or air
conditioning, it will have 2 drive belts. One belt
drives the generator, the other drives the Power
Steering and Air Conditioning. (Fig. 2)
COOLANT RECOVERY SYSTEM (CRS)
This system works in conjunction with the radiator
pressure cap to utilize thermal expansion and con-
traction of the coolant to keep the coolant free of
trapped air. The system provides space for expansionand contraction, and a convenient safe method for
checking and adjusting the coolant level at atmo-
spheric pressure without removing the pressure cap.
It also provides some reserve coolant to compensate
for minor leaks and evaporation or boiling losses. All
vehicles are equipped with this system (Fig. 3).
