(4) Insert muffler pipe into catalytic converter pipe
until the hangers are positioned as shown in (Fig. 11)
CAUTION: Band clamps should never be tightened
such that the two sides of the clamps are bottomed
out against the center hourglass shaped centerblock. Once this occurs, the clamp band has been
stretched and has lost its clamping force and must
be replaced.
To replace the band clamp; remove the nut and peel
back the ends of the clamp until spot weld breaks.
Clean remaining spot weld from the pipe using a
file or grinder until surface is smooth.
NOTE: Maintain proper clamp orientation when
replacing with new clamp.
(5) Tighten the band clamp to 55 N´m (40 ft. lbs.)
(Fig. 12).
(6) Connect the right side half shaft to the rear
differential module (AWD equipped only).

DESCRIPTION
DESCRIPTION - FRONT CRADLE
CROSSMEMBER
This vehicle uses a one piece cast aluminum cradle
for the front cradle crossmember. The cradle cross-
member is used as the attaching points for the lower
control arms, stabilizer bar and steering gear. The
cradle also has the power steering hoses and the
chassis brake tubes attached to it.
WARNING: If a threaded hole in the suspension cra-
dle needs to be repaired, only use the type of
thread insert and installation procedure specified
for this application.
The threaded holes in the front cradle crossmem-
ber that are used for attachment of the lower control
arm rear bushing retainer, power steering hose and
chassis brake tubes can be repaired. The repair is
done by the installation of a Heli-Coiltthread insert
which has been specifically developed for this appli-
cation. Refer to the Mopar Parts Catalog for the spec-
ified Heli-Coiltthread insert to be used for this
application. The procedure for installing the Heli-
Coiltthread insert is detailed in the Service Proce-
dures section in this group of the service manual.
DESCRIPTION - FRONT CRADLE
CROSSMEMBER THREAD REPAIR
WARNING: When performing this procedure use
only the thread inserts which are specified in the
Mopar Parts Catalog for this repair procedure.
These thread inserts have been specifically devel-
oped for this application and use of other types of
thread inserts can result in an inferior long term
repair.The threaded holes in the front cradle crossmem-
ber, if damaged, can repaired by installing a Heli-
Coiltthread insert.
The threaded holes that are repairable using the
thread insert, are the lower control arm rear bushing
retainer mounting bolt holes, routing bracket attach-
ing locations for the power steering hoses, and brake
hose attachment holes.
This repair procedure now allows the threaded
holes in the cradle crossmember to be repaired, elim-
inating the need to replace the cradle crossmember if
damage occurs to one of the threaded holes.
The thread inserts for this application are specified
by part number in the Mopar Parts Catalog.Do not
use a substitute thread insert.
The specific tools and equipment required to install
the thread insert are listed below. Refer to the
instructions included with the thread insert for the
detailed procedure used for the installation of the
thread insert.
NOTE: The thread inserts for this application are for
the repair of M8x1.25 and M10x1.5 threads. Be sure
the correct tools are used for the required thread
insert size.

nated fuel in this system. If it is necessary to replace
these lines/tubes/hoses, use new original equipment
lines/tubes/hoses.
If equipped:The hose clamps used to secure rub-
ber hoses on vehicles are of a special rolled edge con-
struction. This construction is used to prevent the
edge of the clamp from cutting into the hose. Only
these rolled edge type clamps may be used in this
system. All other types of clamps may cut into the
hoses and cause leaks.
Use new original equipment type hose clamps.
STANDARD PROCEDURE - HOSES AND CLAMP
Inspect all hose connections (clamps and quick con-
nect fittings) for completeness and leaks. Replace
cracked, scuffed, or swelled hoses. Replace hoses that
rub against other vehicle components or show sign of
wear.
Fuel injected vehicles use specially constructed
hoses. When replacing hoses, only use hoses marked
EFM/EFI.
When installing hoses, ensure that they are routed
away from contact with other vehicle components
that could rub against them and cause failure. Avoid
contact with clamps or other components that cause
abrasions or scuffing. Ensure that rubber hoses are
properly routed and avoid heat sources.
The hose clamps have rolled edges to prevent the
clamp from cutting into the hose. Only use clamps
that are original equipment or equivalent. Other
types of clamps may cut into the hoses and cause
high pressure fuel leaks. Tighten hose clamps to 1
N´m (9 in. lbs.) torque.
Inspect all hose connections such as clamps, cou-
plings and fittings to make sure they are secure and
leaks are not present. The component should be
replaced immediately if there is any evidence of deg-
radation that could result in failure.
Never attempt to repair a plastic fuel line/tube.
Replace as necessary.
Avoid contact of any fuel tubes/hoses with other
vehicle components that could cause abrasions or
scuffing. Be sure that the plastic fuel lines/tubes are
properly routed to prevent pinching and to avoid heat
sources.
FUEL PRESSURE REGULATOR
OPERATION
The fuel system uses a nonadjustable pressure reg-
ulator that maintains fuel system pressure at
approximately 400  34 kPa (58  5 psi). The fuel
pressure regulator contains a diaphragm, calibrated
spring and a fuel return valve. The spring pushes
down on the diaphragm and closes off the fuel returnport. System fuel pressure reflects the amount of fuel
pressure required to open the return port.
The pressure regulator is a mechanical device that
is NOT controlled by the PCM or engine vacuum.
REMOVAL
The fuel pressure regulator is part of the fuel
pump module (Fig. 8). Remove the fuel pump module
from the fuel tank to access the fuel pressure regula-
tor. Refer to the Fuel Pump Module removal in this
section.
(1) Squeeze tangs on pressure regulator retainer
and pull to remove retainer.
(2) Pry fuel pressure regulator out of housing.
(3) Ensure both upper and lower O-rings were
removed with regulator.
INSTALLATION
The fuel pressure regulator is part of the fuel
pump module. Remove the fuel pump module from
the fuel tank to access the fuel pressure regulator.
Refer to the Fuel Pump Module removal in this sec-
tion.
(1) Lightly lubricate the O-rings with clean engine
oil and place them into opening in pump module (Fig.
8).
(2) Push regulator into opening in pump module.
(3) Retaining tabs snap into housing.
