I think so.. I was using an aftermarket cv shaft, when I compared it to a stock Golf GTI shaft (supposed to be common with the Scirocco) it was 1/2" longer!! I put in the shorter shaft and now have 5/8" plunge - DS, the PS has 3/8" and has never broken. I will be back on the track in 2 weeks and see if this was the problem. Thanks for your help. (for reference neither of the inside cv's have ever broken, only the DS outer)
