Replacing Rear Wheel Hub/Bearing Assemblies

[millionflame]

I'm going to be replacing both rear hub/bearing aassemblies soon.

I know that they are each a sealed unit and come with the bearings installed already, but what I would like to know is if I have to add grease to these or not?

I'm guessing yes, but this whole sealed hub thing is confusing me.

They are sealed bearings, so you don't add grease.
