Yes, they do. The problem is that the peening is done after assembly, and the bushings first must be pressed into the LCA. This first pressing action is where the lubricant is needed.

I made my own "peening press" out of some old craftsman 1/2 inch drive extentions. The radii on the extentions at the ends matched almost exactly the radii needed on the center sleeve after peening. I just put the extensions into the center sleeve, clamp in a vice and squeeze until the center sleeve is peened properly.
