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.
