Each greasable bolt has 1 hole in it... According to Dexter, the hole exit is supposed to be in a horizontal plane rather than a verticle plane... I haven't sat down ad figured out what forces are in play in the axles, bolts, hangers, etc but I guess that this is the ideal position for the greasable bolt to be in so that grease will flow readily thru it and lubricate the balance of the bolt surface...
The reason is that the max wear areas are at the top and bottom. Where there is wear, there is metal movement in brass bushings. The movement can cause the hole to slowly fill with this moved metal. It has to go somewhere.
