Question:
is it possible to get a set of bearing buddies to go on my trailer i have lost several wheel bearings while on trips up to and including loosing the whole drum and wheel. How do you know when you have enough grease pumped into the bearings. will this grease both the outer and inner bearing. The owners manual says these should be greased every 6000 miles which if true is kind of expensive at $120.00 per axle. your thoughts??

In order to pick out the correct bearing buddy you will need know the pilot hole of your hub. To do this, remove the wheel and tire and remove the grease cap from the center of the hub. Usually it is a metal cap that is just lightly hammered into place. Use a screwdriver to pry off the cap.
Clean the grease off and measure the opening. I have included a video demonstrating the Bearing Buddy.
The Bearing Buddies # BB2080 that you referenced are for hubs with a 2.080 inch hub bore.
When installing bearing protectors on a trailer hub, you will want to fill the hub with as much grease as possible, so that you do not have to pump all that grease into the hub with the grease gun after installing the bearings and seals. This also helps to prevent pressure build up in the hub and blow out of the seal in the back of the hub. This will apply grease to both the inner and outer bearings.
When using a bearing protector you should always use a double lip seal, like part # RG06-020, which has two sealing lips and a spring to keep tension of the spindle and help keep pressure from adding grease from blowing out the back of the seal.
Our video showing the bearing installation, see link, is also correct for installation of bearings on a trailer that is not going to have bearing protectors installed in the hub.
