Wtf??? Now im confused.mine look like the gun drilled.guess ill see if a zerk fits in it tommorrow.maybe my eyes are just fawked!
Stock birfs and LFs have a hole tapped into the end. It is not for a zerk (at least not any I have). A 10x1.25 bolt, IIRC, screws into that hole to help 'pull' the axles out slightly when trying to put the snap ring back on. I do not have birfs that are drilled all the way thru (which would be the purpose of having a zerk hole there) but I have that hole for (im assuming) the reason I use it for.
