Do Sealed Bearings Need Grease

As far as I know you leave them alone. Wipe off external crap.
If/when the grease inside is gone, or contaminated the bearings will fail.

They are called "sealed bearings" for a reason. There is no way to grease a sealed bearing.

Like @Wildlife said - if they need grease, they need replacing

They're like the closed transmission systems in some vehicles. They made them to where they don't need maintenance or, as some people would say, can only be maintained by authorized mechanics at the dealerships.
