Rob, do your Bearing Buddy's have a "Blue Grease Indicator Ring" on them? Usually there is a small cover on that blue ring that just pops off using a small flat blade screwdriver. The cover cap is usually embossed or stamped with the Bearing Buddy logo. The grease fitting is located under that cover cap.
I cannot say this enough,,,,,,pump the grease gun SLOWLY! Pumping it fast is a sure fire way to over pressurize the hub and cause a seal failure or cause the Bearing Buddy's pressure bypass valve to start continuously leaking grease slowly. I'll try taking a picture of mine in the moring and post it so you can compare to your trailer.
