ok, thanks for info...I must have the pre 09' version then. I am assuming those bolts allow grease to travel linearly then hit a midpoint in the bolt and travel out to the inards of the joint itself? This is assuming the "sphere" ,that the bolt goes into and allows articulation, has holes in it as well to accept the grease and allow coating around it inside the setting, otherwise the grease would stay inside the bolt which wouldnt do any good.
