13. Fill the inner joint with grease from the grease packet.

14. Move the inner boot on the shaft until the boot seats in the groove of the shaft and the inner joint housing.

15. Secure the inner boot on the shaft and the housing with the clamps. Tighten the clamps with the crimping tool J–22610.

16. Slide the halfshaft splines into the geared hub.

17. Apply thread-locking compound to the halfshaft retaining bolt and secure the halfshaft to the geared hub with the lockwasher

and the halfshaft retaining bolt. Tighten the halfshaft retaining bolt to 37 lb-ft. (50 N•m) (Figure  9-56).

18. Install the washer and the access plug into the geared hub. Tighten the access plug to 8-13 lb-ft. (11-18 N•m).

NOTE:  Ensure all six bolt holes in the rotor align with the holes in the output flange. Make sure the mounting holes and bolts are
cleared of old Loctite.
