Replacing the Driveshaft Carrier Bearing:
According to a source online:
"The driveline carrier brg can be replaced without special tools. It only looks hard. In the worst case, you might need an impact wrench to remove the companion flange nut, and a std gear/jaw puller to pull the flange off the driveshaft, but the last one I did did not require either of those. You willneed the correct size socket for the companion flange nut. I don't recall its size; probably 27mm or 30mm, but that's only a guess. 
Torque down bolts (center flange bolts and rear flange bolts) on driveshaft to 17-24 lb-ft.
Torque down carrier bearing bracket down to 12-16 lb-ft.

A direct fit for a water pump bolt set is available from the Z store as part number 14-1256.

Torque down driveshaft nut to 145-174 ft-lb
