Your bearings tell you if they need replacement during your inspection process. If you see carbon black in the grease then you need to replace your bearings, seal and dust cap.
If you do not see carbon black then your bearings are good and may need repacking if the grease looks hardened.
Carbon black is actually a sign that the casting of your roller bearings and journals have begun the wearing process. These bearings will not be far away from total collapse.
Another thing to look out for is your dust-cap. Dust-caps are a compression fit. If used repeatably the cap loses its compression and will fall off on the highway.
Note: Does not incl wheel nuts.
