Installing
Installation is carried out in the reverse order;
when doing this note the following:

Note:

After removing the driveshaft, it is important to
clean any remaining locking compound out of
the threads in the drive flanges on the
transmission and rear final drive. If this is
neglected, the new bolts can seize when they
are screwed in and shear off later if they have
to be removed.
The threaded holes can be cleaned with a
thread tap.
Replace gasket between driveshaft and drive
flange (pull off backing foil and stick gasket onto
drive flange). Surface must be free of grease.
Replace driveshaft bolts (self-locking).

- If there is a factory marking on the driveshaft,
measure the radial run-out at the flange for the
driveshaft ( Page 39
-73
) and align the paint
marking on the driveshaft with new marking on
the flange.
