If there are no marks, mark the position of the flexible disc with respect to the Haldex clutch flange -arrows-.   Caution Mark the position of the bolts, as some of them may have a balancing washer for preventing vibrations.

–  Remove the bolts -arrows- from the final group flange. –  Carefully pull the cardan shaft to uncouple it from the final group flange centring pivot.   Note

t  Do not bend the cardan shaft when removing it; separate it from the centring pivot while keeping it horizontal. Do not damage the seal in the dowel sleeve -arrow-. t  Do not separate the flexible disc from the vibration damper.
