I’ll be working on the bottom end of the column next. You think the same applies to the bearing down there? Not the plastic white one, I’m talking the metal collar bearing that nestles into the bottom of the white one. You can see the bottom of that bearing housing meeting the white plastic collar in the pic. Thankfully this is not my column!
The lower bearing would have some grease in it. It's more exposed to the elements. Some models don't even have a lower bearing. A little grease in the upper could hurt. I wouldn't pack it like a wheel bearing, just lubricate.
