Replacement
REMOVAL
1. Remove exhaust front pipe, center pipe, heat insulator and center floor crossmember brace
2. Remove propeller shaft, as follows:
a. Using Special Service Tool (SST) 09922-10010 or equivalent, loosen the adjusting nut until it can be turned by hand.
NOTE: Use two of the same type of SST.
b. Place matchmarks on the transmission/differential side companion flange and flexible coupling.
c. Remove the three bolts inserted in the transmission/differential side companion flange.
NOTICE: The bolts inserted in the propeller shaft flange should not be removed.
d. Separate the flexible couplings from the transmission side and differential side.
NOTE: If the flexible coupling cannot be easily separated by hand, insert a screwdriver into the bolt hole o 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 two center support bearing set bolts and the adjusting washers.
NOTE: 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°.
h. 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.
i. Pull the propeller shaft out toward the vehicle's rear.
NOTICE: The intermediate shaft and propeller shaft should not be separated.
CENTER SUPPORT BEARING AND FLEXIBLE COUPLINGS INSPECTION
1. Inspect center support bearing.
- Check for cracks in or damage to the cushion.
- 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 an-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.
PROPELLER SHAFT INSTALLATION
1. Install propeller shaft, as follows:
a. Apply grease to the flexible coupling centering bushings.
Grease: Molybdenum disulfide lithium base, NLGI No.1 or No.2.
b. Insert 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 two center support bearing set bolts with the adjusting washers.
NOTE: Use the adjusting washers which were removed.
d. Align the matchmarks and connect the propeller shaft to the transmission.
e. Install the three bolts, washers and nuts.
NOTICE: Bolts should be inserted from the propeller shaft side.
Torque: 79 Nm (58 ft. lbs.).
f. Align the matchmarks and install the propeller shaft on the differential with the three bolts, washers and nuts.
NOTICE: Bolts should be inserted from the propeller shaft side.
Torque: 79 Nm (58 ft. lbs.).
If using a new propeller shaft with Phase marks:
Install the propeller shaft phase marks and differential phase marks so that their respective alignment phase marks match.
If the propeller shaft phase marks and differential phase marks do not align, install the propeller shaft and differential alignment phase marks are as close together as possible.
Without Phase marks:
Install the propeller shaft.
g. Torque the center support bearing set bolts.
Torque: 49 Nm (36 ft. lbs).
NOTE: Adjust the center support bearing to keep the dimension within the limits, as shown. Under the same condition, check if the center line of the center support bearing is at right angles to the shaft axial direction.
h. Using Special Service Tool (SST) 09922-10010 or equivalent, tighten the adjusting nut.
Torque: 50 Nm (37 ft. lbs.).
NOTE: Use a torque wrench with a fulcrum length of 345 mm (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, heat insulator, exhaust center pipe, front pipe.
