Accessory Driveshaft
From Citroen SM Wiki
There are three main types of front couplings. The USA had the third.
All types are satisfactory, provided the rubber in the couplings is not split.
The rubber coupling has alternate supplies.
- Do not over-tighten the slip joint by the engine, it is easy to strip the thread on the bolt.
- Replace the nut with one with more threads inside.
