Lubricate control arm bushing threads?

[Railroadman]

I will grease - or not grease - whatever those who have done it say. I'm learning as I go. Not a n00b at auto mechanical projects overall, but have not done this task before. I'm not ashamed to say I don't know what's correct and what's not.

So inner threads OK, outer threads maybe a little to ease it going in, but don't let it build up to where the grease will get on the contact area? Makes sense.

Thank you!
