Thanks Doug, that's very helpful to know the number on the back of your hub. Unfortunately mine does not have a number like that, but knowing yours might help me narrow down what I need.
As for etrailer, I did look around there - I see a number of 5 on 4 1/2" hubs. The only thing is that I don't see any of them that have bearing numbers that match the bearing numbers from the four winns parts site. The four winns parts site lists the bearing numbers: 52280 Inner Bearing (1.75") and 15123 Outer (1.25"). Those numbers are from here:

G%2F99-Z00The third reply on the thread at the following link mentions that in the past Four Winns used bearings with a higher than normal capacity on their 5 lug hub so I'm wondering if maybe that's what I'm running into here? The bearings are maybe not what you'd normally use/find so that may be why I can't find an off the shelf hub replacement kit that works?

viewtopic.php?f=12&t=11704 The only thing is that they're just buying the bearings, and not the whole hub replacement kit (which would just be easier to deal with if I had to use it on the road).
Thanks again for the info, I'll update this thread with anything more that I learn ... in the meantime, any additional thoughts/suggestions are more than welcome!
Thanks,
