Drive/Propeller Shaft: Service and Repair

REMOVAL
1. REMOVE FRONT EXHAUST PIPE
2. REMOVE HEAT INSULATOR AND CENTER FLOOR CROSSMEMBER BRACE
a. Remove the 4 nuts and heat insulator.
b. Remove the 4 bolts and center floor crossmember brace.
3. REMOVE PROPELLER SHAFT





a. Using SST, loosen the adjusting nut until it can be turned by hand.
SST 09922-10010

HINT: Use 2 of the same type of SST





b. Place matchmarks on the transmission/differential side companion flange and flexible coupling.
c. Remove the 3 bolts installed in the transmission/differential side companion flange.

NOTICE: The bolts installed in the propeller shaft flange should not be removed.





d. Separate the flexible couplings from the transmission and differential side.

HINT: If the flexible coupling cannot be easily separated by hand, insert a screwdriver into the bolt hole of the flexible coupling, as shown in the illustration, then pry the coupling out.

NOTICE: Do not bring the screwdriver blade in direct contact with the flexible coupling's rubber portion.

e. Remove the 2 center support bearing set bolts and the adjusting washers.

HINT: Some vehicles are not equipped with an adjusting washer.

NOTICE: When removing the set bolts, support the center support bearing by hand so that the transmission and intermediate, shaft, and propeller shaft and differential, remain In a straight line.

Maximum joint angle: 5°

f. Push the rear propeller shaft straight forward to compress the propeller shaft and pull out the propeller shaft from the centering pin of the differential.

NOTICE: Press the propeller shaft straight ahead to keep the transmission and intermediate shaft aligned straight.

g. Pull the propeller shaft out toward the vehicle's rear.

NOTICE: The intermediate shaft and propeller shaft should not be separated.

INSPECTION
1. INSPECT CENTER SUPPORT BEARING





a. Check for cracks in or damage to the cushion.
b. Check if the bearing turns smoothly.
If the center support bearing is damaged, worn or does not turn smoothly, replace it.





2. INSPECT FLEXIBLE COUPLINGS
Check for cracks in or damage to the front and rear flexible couplings.
If the flexible coupling is damaged, replace the propeller shaft assembly.
3. INSPECT FLEXIBLE COUPLING CENTERING BUSHING
Check for damage to the bushing. If the bushing is damaged, replace the propeller shaft assembly.





4. INSPECT RUNOUT OF INTERMEDIATE SHAFT AND PROPELLER SHAFT

Maximum runout: 0.8 mm (0.031 inch)

If the runout exceeds the maximum, replace the propeller shaft assembly.
5. INSPECT SPIDER BEARING





a. Check if the spider bearing rotates smoothly.
b. Check if there any play in the spider bearing. If necessary, replace the propeller shaft assembly.

REPLACEMENT

NOTICE: Be careful not to grip the propeller shaft tube too tightly In a vise as this will cause deformation.

1. SEPARATE INTERMEDIATE SHAFT AND PROPELLER SHAFT





a. Place matchmarks on the intermediate shaft and propeller shaft.
b. Separate the intermediate shaft and propeller shaft.
c. Remove the dust boot from the propeller shaft.

HINT: If the dust boot is reused, remove it after wrapping vinyl tape around the spline, so it will not be damaged.

2. REMOVE CENTER SUPPORT BEARING





a. Using a snap ring expander, remove the snap ring.
b. Using SST and a press, remove the center support bearing and dust deflector.
SST 09950-00020
3. INSTALL CENTER SUPPORT BEARING





a. Using SST and a press, install the center support bearing.
SST 09330-50010





b. Using SST and a press, insert a new dust deflector until it almost touches the rubber of the center support bearing.
SST 09608-00071, 09608-06041





c. Using SST and a press, install a new dust deflector to the end.
SST 09330-50010
d. Using a snap ring expander, install a new snap ring.
4. ASSEMBLE INTERMEDIATE SHAFT AND PROPELLER SHAFT





a. Install the dust boot.

NOTICE: Assemble after wrapping vinyl tape around the spline so it will not damage the boot.

b. Apply grease to the spline.

Grease: Molybdenum disulfide lithium base, NLGI No.2.

c. Align the matchmarks and assemble the intermediate shaft and propeller shaft.
d. Cover the adjusting nut with the dust boot.





NOTICE: The directions of the intermediate shaft companion flange and the propeller shaft companion flange should differ by 180°

e. Tighten the adjusting nut fully by hand.

INSTALLATION
1. INSTALL PROPELLER SHAFT





a. Apply grease to the flexible coupling centering bushings.

Grease: Molybdenum disulphide lithium base, NLGI No.1 or No.2

b. Install the propeller shaft from the vehicle's rear and connect the transmission and differential.

NOTICE: Support the center support bearing by hand so that the transmission and intermediate shaft, and propeller shaft and differential, remain in a straight line.

c. Temporarily install the 2 center support bearing set bolts with the adjusting washers.

HINT: Use the adjusting washers which were removed.

d. Align the matchmarks and connect the propeller shaft to the transmission/differential.
e. Install and torque the 3 bolts, washers and nuts.

NOTICE: The bolts should be installed from the propeller shaft side.

Torque: 79 Nm (805 kgf-cm, 58 ft. lbs.)





f. If using a new propeller shaft (w/ Phasemarks):
- Install the propeller shaft phasemarks and differential phasemarks so that their respective alignment phasemarks match.
- If the propeller shaft phasemarks and differential phasemarks do not align, install the propeller shaft and differential alignment phasemarks as close together as possible.
g. If using a new propeller shaft (w/o Phasemarks):
- Install the propeller shaft.





h. Torque the 2 center support bearing set bolts.

Torque: 49 Nm (500 kgf-cm, 36 ft. lbs.)

HINT: Adjust the center support bearing to keep the dimension as shown with the vehicle in the unladen condition. Under the same condition, check if the center line of the center support bearing is at right angles to the shaft axial direction.





i. Using SST, tighten the adjusting nut.
SST 09922-10010

Torque: 50 Nm (515 kgf-cm, 37 ft. lbs.)

HINT: Use a torque wrench with a fulcrum length of 34.5 cm (13.6 inch).

2. INSPECT JOINT ANGLE

NOTICE: The joint angle should by all means be checked when the propeller shaft is removed and installed.

3. INSTALL CENTER FLOOR CROSSMEMBER BRACE AND HEAT INSULATOR
a. Install the 4 bolts and center floor crossmember brace.

Torque: 13 Nm (130 kgf-cm, 9 ft. lbs.)

b. Install the 4 nuts and heat insulator.

Torque: 5.4 Nm (55 kgf-cm, 48 inch lbs.)

4. INSTALL FRONT EXHAUST PIPE
