EXHAUST SYSTEM
REMOVAL
It is easier to service any portion of the exhaust
system if the entire exhaust system (except the ex-
haust manifolds) is removed from the vehicle.
(1) Raise vehicle on swing arm hoist.
(2) Apply penetrating oil and remove to the front
down pipes to exhaust manifolds nuts (Fig. 4).
(3) Apply penetrating oil and remove to the front
down pipes intermediate transmission support
bracket bolts.
(4) Remove the rubber isolators from the welded
exhaust system rod wire hangers (Fig. 3).
CAUTION: At this time,the exhaust system is held
by only isolators. Support the exhaust system un-
derneath the underfloor convertor and the muffler
while the isolators are being removed. Do not use
any tools to remove the isolators, remove by hand
only. Soapy water or silicone-based spray may be
used to assist removal. DO NOT USE A PETRO-
LEUM-BASED LUBRICANT ON THE ISOLATORS,
This will damage the rubber material.
(5) Carefully maneuver the front down pipes past
the engine, engine support cradle, and transmission.
Lay the exhaust system on the ground.
When replacement is required on any compo-
nent of the exhaust system, it is most important
that original equipment parts be used;
•
To insure proper alignment with other parts in the
system.
•
Provide acceptable exhaust noise levels and does not
change exhaust system back pressure that could affect
emissions and performance.
INSTALLATION
(1) Install and loose assemble the front pipes to the
exhaust manifolds and the transmission support
bracket.
(2) Place the exhaust module onto two supports (one
under the underfloor catalytic convertor, one under the
muffler). Slide the module forward onto the front pipes
until the front of the underfloor convertor inlet bush-
ings are touching the dimples on the front pipes.
(3) Install the module’s rubber isolators onto the
body brackets.
(4) Visually inspect the isolators. They should be
straight when viewing from front to back of the vehicle.
Working from the front of system, align each compo-
nent to maintain position and proper clearance with
underbody parts.
(5) Orientate and tighten all clamps and supports to
the proper torques and clearances (Fig. 5).
(6) Lower the vehicle.
