The easiest thing to do to check if anything is broken is to jack up the trailer and grab the tire at 12 & 6 and see if it rocks back and forth. If it doesnt, then it should be ok and it just means that your bearing buddy is leaking so just keep it greased. If it does move, then that means your bearings are shot and/or broken. Then you're getting into a whole new mess depending on how much damage was done. But for now try that and see what happens.
