took the s2 out for a run today and when i got in after around 30 miles there was cv grease all over drivers wheel so knew something had happend to it, the strange thing is when i stuck my head underneath to see where it had split it hadn't but instead is all twisted like it's a towel thats been rung out or when you get something cought in a drill it twists it round. now not sure how this has happened as both the shaft and hub are always at same speed as joined together or does this point to some problem about to bite me in the arse?

could be lack of grease inside or cable tie has just snapped.replace one of mine the other week but was only split horrible job good luck
