Center Support: Service and Repair

NOTE: Before replacing the center support bearing the drive/propeller shaft must be removed. Refer to "Drive/Propeller Shaft, Service and Repair."

NOTICE: When performing operations which involve the removal and installation of the propeller shaft. always check the joint angle. Make adjustments if necessary.


CENTER SUPPORT BEARING REPLACEMENT
1. Separate intermediate shaft and propeller shaft, as follows:





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.

NOTE: 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, as follows:
a. Using a snap ring expander, remove the snap ring.





b. Using Special Service Tool (SST) 09950-00020 or equivalent, remove the center support bearing and dust deflector.





3. Inspect intermediate shaft and propeller shaft runout.
Maximum runout: 0.8 mm (0.031 inch).
If the runout is greater than the maximum, replace the propeller shaft assembly.





4. Inspect spider bearing.
- Check if the spider bearing rotates smoothly.
- Check if there is any play in the spider bearing. If necessary, replace the propeller shaft.
5. Install center support bearing, as follows:

d. Using a snap ring expander, install a new snap ring.
6. Assemble intermediate shaft and propeller shaft, as follows:
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.
