I had difficulty repling to your post so I hope you find this: I would take a look a t this page and review the articles to understand how the components should look pre-explosion. http://www.championtrailers.com/techsup.html#technical_support I will tell you that after a very bad experience I no longer buy anything from Champion Trailer; I would recommend http://www.portstrailersupply.com/ or http://easternmarine.com/index.html. The bearing buddy needs to be removed with a rubber mallet or a hammer and a piece of scrap wood by tapping it on all sides. Once the buddy is off you can look inside the end of the hub and see a large nut. Remove with channel lock pliers and the hub should come off with bearings or what is left of them. You should now be left with shoes and backing plate that is bolted to a square flange on the axle. When bearings explode they are actually burning up. The heat can cause things to "weld" together so I would not be shy about using some force to get things apart. This heat can ruin a spindle which may require a replacement axle. New spindles can be welded on but but getting them on straught is tough and a whole new axle is not that expensive. Once you solve the big problem you wil need to repack the bearings on the other wheels. This is fairly straight forward work and should be within reach of those qualified to pump self serve gas. If you have questions, Portsmouth or Eastern should be able to provide help over the phone.
