Lower control arm question

When pressing in the new bushing, are you supposed to put a little grease on the shell before pressing. I think the FSM says no grease on the rubber part but what about the metal to metal parts?
i put a little slippery stuff on the the metal to metal parts. inspect and test fit everything first, it would suck to get a bushing in and then learn that the pin hole is all sloppy AF. go slow and steady and try to avoid using the threaded end of the pin as a press point, it'll F out the threads and likely the pin will go in cocked and you'll get to buy a new bushing and do it all again.
