On my onroad cars:

I usually take a rag dampened with motor spray and wipe the external seals to remove as much dust and debris as possible before anything else.

If you use rubber sealed bearings, you can carefully remove the seals with a hobby blade, then use the RPM bearing blaster with your cleaner of choice to flush them, inspect/listen for free spinning, relube with a high quality oil and reinstall the seals.

For shielded bearings I'll try to clean them without removing the shields the same as above and relube.

Plenty of places offer $1 bearing multi-packs [10/$10], so any suspect bearing gets replaced.

For my off-road cars:

Leave the factory lube in the bearings, wipe the seals with a damp rag as above, feel for any drag or grit. Replace if any is found.

Almost never have any luck trying to clean bearings in an off-road vehicle.

You can not weigh them?
The ceramic bearings should be somewhat lighter in weight.
