Hello Gary, thanks for reaching out. We should definitely have the correct bearings and hubs for you, but I will need a bit more info from you first. RV manufacturers do not get that specific with their online literature unfortunately.

If you can tell me the weight capacity of each axle, that will help to narrow things down. If you remove a tire, there should be a number stamped on the front of each hub. Most of the time we can look up that number to know exactly what you need.

Reply below with that info and I am happy to look into it and get back to you with some part numbers.
