Your bearings will tell you if they need replacement during your inspection. If you see carbon black in the grease, you need to replace your bearings, seal, and dust cap.

If you do not see carbon black, your bearings are suitable and may need repacking if the grease looks hardened.

Carbon black is a sign that the casting of your roller bearings and journals has 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 repeatedly, the cap will lose its compression and fall off on the highway.

Couplemate recommends buying and installing new dust caps after checking bearings.
