It would be interesting to know if there have been any failures of CDD's Rotoflex replacement CV shafts and how said driveshaft failed (snapping,shearing or other failure)?
Out of curiosity, a while ago, I Googled the part number on the outer CV joint on my Vit MK 2 CDD CV shafts. It appears to be the same as a mk 3 Escort (FWD). The reported failures mentioned all seem to be to be with non- roto shafts, apart from the one Stag failure mentioned,which is non roto of course.
