Barbell Maintenance - Bearings?

This probably won't apply to most of y'all, but to those who have an Oly-size weight set at home, do you do anything with barbell maintenance? Especially for the rotating ends? I don't have the best bar in the world, but it's pretty decent. Lately, though I've noticed that the weights spin freeer than the ends of the bar (which were made to spin). I'm thinking about taking the ends off and greasing the insides, but I want to make sure I don't lose anything when I take it apart. I know I've seen some stuff on this a few years ago. I may just need to Google it..'
