Removal and InstallationNBS005RL
CAUTION:

Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat
resistance, corrosion resistance, and shape.

Perform the operation with the exhaust system fully cooled down because the system will be hot
just after engine stops.

Be careful not to cut your hand on the heat insulator edge.
REMOVAL

Disconnect each joint and mounting using power tool.

Remove heated oxygen sensor 2 as follows:
–Using heated oxygen sensor wrench (SST), removal heated
oxygen sensor 2.
CAUTION:
Be careful not to damage heated oxygen sensor 2.
INSTALLATION
Note the following, and install in the reverse order of removal.

Check for deformation of the grommets (18 and 20 of Components).

Insert the collar (17 of Components) vertically.

Install the collar (5 of Components) with its lower surface horizontal.

Temporarily tighten nuts and bolts when installing exhaust pipe assembly. Tighten them to the specified
torque when connecting the vehicle rear to the vehicle front.
CAUTION:

Always replace exhaust tube gaskets with new ones when reassembling.

Discard any heated oxygen sensor which has been dropped onto a hard surface such as a con-
crete floor. Use a new one.

Before installing a new heated oxygen sensor, clean exhaust system threads using the heated
oxygen sensor thread cleaner [commercial service tool: J-43897-18 or J-43897-12], and apply the
anti-seize lubricant (commercial service tool).

Do not over torque heated oxygen sensor. Doing so may cause damage to heated oxygen sensor,
resulting in the “MIL” coming on.

If heat insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the heat
insulator, remove them.

When installing heat insulator avoid large gaps or interference between heat insulator and each
exhaust pipe.

Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gases leakage.

Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehi-
cle side. Check each part for unusual interference, and then tighten them to the specified torque.

When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/
left directions.
INSPECTION AFTER INSTALLATION

Make sure clearance between tail tube and rear bumper is even.

With engine running, check exhaust tube joints for gas leakage and unusual noises.

Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.

PRECAUTIONS
Revision: 2007 April2007 M35/M45
PRECAUTIONSPFP:00001
CautionNDS000FB
Observe the following precautions when disassembling and assembling drive shaft.

Joint sub-assembly does not disassemble because it is non-overhaul parts.

Perform work in a location which is as dust-free as possible.

Before disassembling and assembling, clean the outside of parts.

Prevention of the entry of foreign objects must be taken into account during disassembly of the service
location.

Disassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean
cover must be placed over parts.

Paper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint adher-
ing to parts.

Disassembled parts (except for rubber parts) should be cleaned with kerosene which shall be removed by
blowing with air or wiping with paper shop cloths.
