Hey Colsen. I have some bad news for you. There are no hubs with bearings item # LM48548 and M12649 available. I checked elsewhere and there isn't a hub I can find anywhere that uses those bearings.
The only solution I have for you is to replace the axle with one that uses modern spindles, so long as yours does not have a bend in it. We do offer some off-the-shelf axles in the more popular sizes. To choose the correct replacement, I'll need to know the axle capacity or the GVWR of your trailer, the hub face to hub face dimension, and the center to center distance between the spring seats.
