29. Install knock sensor (1) with connector facing toward the rear of
engine.
CAUTION:

Never tighten bolts while holding the connector.

If any impact by dropping is applied to knock sensor,
replace it with a new one.
NOTE:

Make sure that there is no foreign material on the cylinder
block mating surface and the back surface of knock sensor.

Make sure that knock sensor does not interfere with other parts.
30. Install crankshaft position sensor (POS) and crankshaft position sensor (POS) cover.
CAUTION:

Avoid impacts such as a dropping.

Keep it away from metal particles.

Never place sensor in a location where it is exposed to magnetism.
31. Install oil filter (for intake valve timing control) (1) in the direction
shown.

Make sure that the oil filter does not protrude from the upper
surface of cylinder block (2) after installation.

Removal and InstallationEBS00TSS
REMOVAL
CAUTION:

Be sure to use genuine NISSAN 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 the engine stops.

Be careful not to cut your hand on heat insulator edge.
1. Disconnect harness connector of heated oxygen sensor 2.

Using Tool, remove heated oxygen sensor 2.
CAUTION:
Be careful not to damage heated oxygen sensor 2.
a.2. Disconnect each joint and mounting rubber.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:

Always replace exhaust gaskets and seal bearings with new ones when installing.

Discard any heated oxygen sensor 2 which has been dropped from a height of more than 0.5 m
(19.7 in) onto a hard surface such as a concrete floor; use a new one.

Before installing a new heated oxygen sensor 2, clean exhaust system threads using the heated
oxygen sensor thread cleaner and apply anti-seize lubricant (commercial service tool).

Do not over tighten heated oxygen sensor 2. Doing so may cause damage to the heated oxygen
sensor 2, resulting in the “MIL” coming on.

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

Temporarily tighten nuts on the exhaust manifold side and bolts on the vehicle 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.
Exhaust Manifold to Exhaust Front Tube
1. Securely insert seal bearing (2) into exhaust manifold (1) side in
the direction shown.

Exhaust front tube (5)
CAUTION:
Be careful not to damage seal bearing surface when install-
ing.
2. Install spring (3), tighten nut (4).

Be careful that the stud bolt nut does not interfere with the
flanged area ( ).

Make sure the spring (3) sits properly on the flange surface by
align it to the locator dimples.Tool number : KV10114400 (J-38365)PBIC3797E

in the direction shown.

Center muffler (5)
CAUTION:
Be careful not to damage seal bearing surface when install-
ing.
2. With spring (3), tighten bolt (4).

Be careful that the stud bolt does not interfere with the flanged
area ( ).
INSPECTION AFTER INSTALLATION

With the engine running, check exhaust tube joints for exhaust leakage and unusual noise.

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

7. Pry off drive shaft from transaxle assembly side as shown.

Make sure that circlip is attached on the edge.
CAUTION:

Do not apply an excessive angle to drive shaft joint when
removing from the transaxle.

Do not excessively extend slide joint.

Do not allow drive shaft to hang down. Support the entire
drive shaft.
INSPECTION AFTER REMOVAL

Move joint up/down, left/right, and in axial direction. Check for any rough movement or significant loose-
ness.

Check boot for cracks or other damage, and for grease leakage.

If damaged, disassemble drive shaft to verify damage, and
repair or replace as necessary.
INSTALLATION
Installation is in the reverse order of removal. Note the following:

Refer to FAX-8, "COMPONENTS" for tightening torque.
CAUTION:
Do not reuse non-reusable parts.

In order to prevent damage to differential side oil seal, place Tool
onto oil seal before inserting drive shaft as shown. Slide drive
shaft into slide joint and tap with a hammer to install securely.

Install new circlip on drive shaft in the circlip groove on transaxle
side. Refer to FAX-12, "
Disassembly and Assembly (Left Side)" .
CAUTION:
Make sure the new circlip on the drive shaft is securely fas-
tened.

After its insertion, try to pull the flange out of the slide joint by
hand. If it pulls out, the circlip is not properly meshed with the
transaxle side gear.
