I was trying to free the front half of the shaft from the front flex disc with a pry bar and,without brain ,I grapped the rear half and pulled on it. The rear half just came off(so easily). So my question is; Is the big nut that surround the slot where the spline goes in supposed to lock the spline in place? In another word, Should the spline came off easily like that? Im guessing that the slot is flexible n can b tightened n opened by the big nut. And for the marking, the relation of the nut to the front shaft are what being marked here, is that correct?
By the way Im working on w116.
Thank you guys
