Final clue to the driveshaft replacement.

Well my indication on driveshaft was wrong. Although the protective sleeve was damaged and that pointed to it.

It turned out that the actual noise was caused by a failing wheel bearing. According to the dealer not the first he replaced.

The damaged driveshaft was repaired but the noise was not caused by this.

So i now have some spare driveshaft

Thanks for all the help and advice.
