Removal Procedure
Notice: Failure to follow the proper removal and installation procedures
may result in damage to the engine crankshaft thrust bearing.
Notice: When tilting down the rear of the driveline, observe the
clearance between the rear of the engine and the composite dash panel. Do
not allow the engine to rest unsupported against the composite dash panel,
or vehicle damage may result.
Notice: When lowering and removing the rear of the driveline, observe
the clearance between the rear of the transaxle assembly and the underbody
to prevent damage.
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing
any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to
the vehicle or its components.
- Disconnect
the negative battery cable. Refer to
Battery Negative Cable Disconnection and Connection
in Engine Electrical.
- Raise and suitably support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the rear tire and wheel assemblies. Refer to
Tire and Wheel Removal and Installation
in Tires
and Wheels.
- Remove the catalytic converter pipe assembly. Refer to
Catalytic Converter Replacement
in Engine Exhaust.
- Tie off the LH muffler assembly to the underbody to support the
muffler out of the way.
- Remove the RH muffler assembly. Refer to
Exhaust Muffler Replacement - Right Side
in Engine Exhaust.
- Remove the driveline tunnel closeout panel. Refer to
Floor Panel Tunnel Panel Reinforcement Replacement
in
Propeller Shaft.
- Using a flat bladed screwdriver,
remove the rear bellhousing access plug.
Important: The following step must be performed to assure proper torque converter
balance during installation.
- Matchmark the transmission flexplate to the transmission torque converter
through the access hole in the rear bellhousing.
- Remove the transmission flexplate to transmission torque converter
bolts. Refer to
Flexplate to Torque Converter Bolts
.
- Remove the two plug bolts
from the front of driveline support assembly.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
Important: The propeller input shaft front bearing positioning bolts are intended
to remain torqued to specification and in place UNTIL INSTRUCTED in the installation
procedure.
Important: Failure to use the minimum length fastener specified will prevent proper
retention of the propeller input shaft front bearing during disassembly or
installation.
- Install two bolts, M10 - 1.5 X 55 mm,
or longer, in place of the plug bolts.
(The long bolts are located to maintain the propeller input shaft front
bearing in original position during removal and installation.)
Tighten
Tighten the propeller input shaft front bearing positioning bolts to
35 N·m (26 lb ft).
- Using a flat bladed screwdriver,
remove the engine flywheel housing access plug.
- Loosen the propeller shaft
hub clamp bolt (1).
Rotate the engine at the flywheel, if necessary for alignment.

to a transmission jack.
- Position and firmly secure the J 42055
with the transmission jack to the transmission.
- Disconnect the wiring
harness and brake pipe clip retainers from the rear suspension crossmember.

securing (and positioning) the wiring harness to the L-shaped brackets along
the driveline support assembly, then slide the harness up out of the brackets
and position out of the way.

approximately 5 cm (2 in), while simultaneously adjusting the
angle of tilt, in order to access the electrical connectors.
- Disconnect the vehicle speed sensor (VSS) electrical connector.
- Disconnect the wiring
harness retainer from the stud at the differential rear cover.
- Disconnect the wiring harness retainer clip from the top of the
differential.

LH side of the transmission case.
- SLOWLY lower the driveline,
while simultaneously adjusting the angle of tilt, and observe the relationship
between the top rear of the differential and the lowest part of the rear
compartment panel floor (the center storage compartment between the frame
rails). The differential should not be lowered more than approximately
EVEN with the specified body point of reference.
(The engine positive crankcase ventilation (PCV) pipes which route along
the rear of the engine intake manifold will likely contact the dash panel.)
- Release the wiring harness from the harness retainer along the
top of the transmission.
- Check to be sure that the wiring harness is free from the driveline
being removed.
- Disconnect the transmission
oil cooler rear pipes from the junction fittings at the engine flywheel housing,
