They are "sealed units" so no official service on them. Some people will pull the ABS sensor and shoot grease into the opening to try an put some fresh grease into the bearings.

Thanks for the reply - I have heard of this, do you know of any youtube vids or other links on it?

Never looked for one.

Pretty much self explaining when you pull the rotors. With a grease gun filled with Wheelbearing grease push 10 strokes of grease while turning the hub.
That's all.
Done so on a regular basis, maybe all 20k Miles your Bearings will last incredibly long.
They die from dried old worn grease, that's all.
