REMOVAL
1. Remove engine undercover with a power tool.
2. If necessary, remove heat bracket.
3. Remove the three way catalyst (right bank) with a power tool. Refer to EX-3, "
EXHAUST SYSTEM" .
4. Put matching marks onto propeller shaft flange yoke and final
drive companion flange.
CAUTION:
For matching marks, use paint. Do not damage propeller
shaft flange and companion flange.
5. Remove the propeller shaft fixing bolts.
6. Remove propeller shaft from the front final drive and transfer.
INSPECTION

Inspect propeller shaft runout at measuring point. If runout
exceeds specifications, replace propeller shaft assembly. For
measuring point, refer to PR-4, "
Propeller Shaft Runout Measur-
ing Point" .

As shown in the figure, while fixing yoke on one side, check axial
play of joint. If outside the standard, replace propeller shaft
assembly.

Check propeller shaft for bend and damage. If damage is
detected, replace propeller shaft assembly.
CAUTION:
Do not disassemble joints.
INSTALLATION
Note the following, install in the reverse order of removal.

Align matching marks to install propeller shaft to final drive com-
panion flange, and then tighten to specified torque. Refer to PR-
4, "Components" .
CAUTION:
Do not reuse the bolts.

After assembly, perform a driving test to check propeller shaft
vibration. If vibration occurred, separate propeller shaft from
final drive or transfer. Reinstall companion flange after rotating it
by 90, 180, 270 degrees. Then perform driving test and check
propeller shaft vibration again at each point.

POWER STEERING OIL PUMPPFP:49110
On-Vehicle Inspection and ServiceNGS000DE
CHECKING RELIEF OIL PRESSURE
CAUTION:
Make sure that belt tension is normal before starting the following procedure.
1. Connect the hydraulic pressure gauge [SST] between oil pump
discharge connector and high-pressure hose. Bleed air from the
hydraulic circuit while opening valve fully. Refer to PS-8, "
Air
Bleeding Hydraulic System" .
2. Start engine. Run engine until oil temperature reaches 50 to
80°C (122 to 176°F).
CAUTION:

Leave the valve of the hydraulic pressure gauge [SST]
fully open while starting and running engine. If engine is
started with the valve closed, the hydraulic pressure in
oil pump goes up to the relief pressure along with
unusual increase of oil temperature.

Be sure to keep hose clear of belts and other parts when
engine is started.
3. Fully close the hydraulic pressure gauge [SST] valve with
engine at idle and measure the relief oil pressure.
CAUTION:
Never keep valve closed for 10 seconds or longer.
4. Open the valve slowly after measuring. Repair oil pump if the
relief oil pressure is outside the standard. Refer to PS-31, "
Dis-
assembly and Assembly (Models with VK45DE)" , PS-35, "Disassembly and Assembly (Models with
VQ35DE)" .
5. After inspection, disconnect the hydraulic pressure gauge [SST] from hydraulic circuit, then add fluid and
bleed air. Refer to PS-8, "
Air Bleeding Hydraulic System" .
Removal and InstallationNGS000DF
REMOVAL
1. Drain power steering fluid from reservoir tank.
2. Remove undercover from vehicle with a power tool.
3. Loosen drive belt. Refer to EM-16, "
DRIVE BELTS" (VQ35DE), EM-174, "DRIVE BELTS" (VK45DE).
4. Remove drive belt from oil pump pulley.
5. Remove piping of high pressure and low pressure (drain fluid from their pipings). Refer to PS-39,
"HYDRAULIC LINE" .
6. Remove power steering oil pump mounting bolts, and then remove power steering oil pump. Refer to PS-
39, "Removal and Installation" .
INSTALLATION
Installation is the reverse order of removal. For tightening torque, refer to PS-39, "HYDRAULIC LINE" .

Perform the following procedure after installing.
–Adjust belt tension (VQ35DE). Refer to EM-16, "Tension Adjustment" .
–About the installation of VK45DE drive belt, refer to EM-174, "Tension Adjustment" .
–Bleed air. Refer to PS-8, "Air Bleeding Hydraulic System" . Relief oil pressure:
8,520 - 9,320 kpa (86.9 - 95.1 kg/cm
2 , 1,235 - 1,351 psi)

PINION/CLUTCH CHECK
1. Inspect pinion teeth.

Replace pinion if teeth are worn or damaged. (Also check condition of ring gear teeth.)
2. Inspect reduction gear teeth.

Replace reduction gear if teeth are worn or damaged. (Also check condition of armature shaft gear
teeth.)
