Pack Front bearings?

[88accordlxcarb]

Do the front bearings in our cars need to be packed after we get them from the parts store? Or do they come wiht grease sealed in them?

If they do need to be repacked, whats the easiest way to get grease to the bearings and "pack" them?

the bearings are sealed and do not need to be greased.
