Installing
Installation is reverse of removal, noting the
following:

- Observe important notes page 39
-73

Notes:

After removing driveshaft, always remove any
remaining locking fluid from thread holes in the
transmission drive flanges and the rear final
drive. Otherwise there is a possibility that the
new bolts may get jammed when installed and
shear when removed.
Cleaning can be performed with a tap.
Replace gaskets on drive flanges (remove
protective film and attach gasket to drive
flanges). Adhesive surface must be free of
grease.

To prevent imbalance, driveshaft flanges -A- and rear final drive
flanges -B- must be installed so that the factory color markings or
markings which were made afterward are aligned (arrows).
