LCA install question

I tried searching the net and the site before asking this question but I couldn't find anyone asking the same question so....
Do I need to grease the k member shaft opening for the LCA pivot pin, I noticed there was grease on my old LCA and in the k member shaft on my old one. I was under the impression that all the movement is supposed to happen at the bushing and not at the shaft, I could see how metal to metal contact over time wouldn't be a good thing but I don't want to apply grease where it shouldn't be, any help would be great.
I have never greased that point. I recently upgraded the LCA's and the old pivots were fine after 13 years.
