N: To preserve 'drive line' refine
ment, individual parts, other than fixings, MUST NOT be renewed. In the event
of any balance or driveshaft component related problem, the complete assembly must be renewed. Under no circumstances
may the flexible (Jurid) coupling be remo ved from the driveshaft (or its fixings be loosened). Do not drop or subject the
driveshaft to damage.

5. CAUTION: Under no circumstances must the
flexible coupling (or its fixings) be loosened or removed
from the drive shaft
1. 'Match mark' the FLEX IBLE COUPLING to the
differential DRIVE FLANGE
2. Remove the fixings (3)
6. Re
move the driveshaft
6. CAUTION: Ensure that the driveshaft front and
rear sections do not become disengaged. Secure the front
and rear sections to preven t sliding joint disengagement
during transport
