The trunnions will not have to be lubed. They will be held in place by dropping into the metal "pockets" that you can see in the pictures which will be welded to metal strapping lining most of the edges of the cheeks. There will also be another "cap" identical to the pocket w/ ears welded on that will use upside down U's and wedge pins to hold the caps on.
