Install and tighten the 3 bolts, 3 washers and 3 nuts.
- Torque:
- 79 N*m{ 805 kgf*cm, 58 ft.*lbf}
- NOTICE:
- Be careful not to damage the flexible coupling centering bushing.
- HINT:
- The bolts should be installed from the propeller shaft side.
Align the matchmarks on the differential companion flange and flexible coupling.
Install and torque the 3 bolts, 3 washers and 3 nuts.
- Torque:
- 79 N*m{ 805 kgf*cm, 58 ft.*lbf}
- NOTICE:
- Be careful not to damage the flexible coupling centering bushing.
- HINT:
- The bolts should be installed from the propeller shaft side.
Temporarily install the 2 center support bearing washers, 2 bolts and 2 center support bearing dampers.
- NOTICE:
- Install the center support bearing damper with the pink area facing downwards.
| 2. FULLY TIGHTEN NO. 1 CENTER SUPPORT BEARING ASSEMBLY |
Adjust the dimension between the edge surface of the center support bearing and the edge surface of the cushion to 11.5 to 13.5 mm (0.4528 to 0.5315 in.) respectively as shown in the illustration.
Check that the center line of the bracket is perpendicular to the shaft axial direction.
Tighten the 2 bolts.
- Torque:
- 49 N*m{ 500 kgf*cm, 36 ft.*lbf}
Using SST, tighten the adjusting nut.
- SST
- 09922-10010
- Torque:
- When not using SST:
- 69 N*m{ 700 kgf*cm, 51 ft.*lbf}
- When using SST:
- 51 N*m{ 520 kgf*cm, 38 ft.*lbf}
- HINT:
| 3. INSPECT AND ADJUST BOTH NO. 2 AND NO. 3 JOINT ANGLES |
Stabilize the propeller shaft and differential.
Turn the propeller shaft several times by hand to stabilize the center support bearing.
Check both the No. 2 and No. 3 joint angles.
Using SST, measure the installation angle of the intermediate shaft and propeller shaft.
- SST
- 09370-50010
- HINT:
- The SST should be set directly on the bottom of the shaft.
Using SST, measure the installation angle of the differential.
- SST
- 09370-50010
- HINT:
- Measure the installation angle by placing the SST in the positions shown in the illustration.
Calculate the No. 2 joint angle.
- No. 2 joint angle:
- A - B = -0°49' to -1°49'
- A:
- Intermediate shaft installation angle
- B:
- Propeller shaft installation angle
Calculate the No. 3 joint angle.
- No. 3 joint angle:
- B - C = 0°70' to 2°10'
- B:
- Propeller shaft installation angle
- C:
- Differential installation angle
- HINT:
- If the measured angle is not within the specified range, adjust it with the center support bearing washers.
Adjust the No. 2 joint angle.
Select the center support bearing washers for adjustment.

- NOTICE:
- The 2 washers should be the same thickness.
| 4. INSTALL OUTSIDE AIR GUIDE PLATE RH |
Install the outside air guide plate RH with the 4 nuts.
- Torque:
- 5.4 N*m{ 55 kgf*cm, 48 in.*lbf}
| 5. INSTALL FRONT NO. 1 FLOOR HEAT INSULATOR |
Install the front No. 1 floor heat insulator with the 4 nuts.
- Torque:
- 5.4 N*m{ 55 kgf*cm, 48 in.*lbf}
| 6. INSTALL FRONT EXHAUST PIPE ASSEMBLY |
| 7. CHECK FOR EXHAUST GAS LEAKS |
