I’m going to replace the hubs on the snowmobile trailer; they’re looking rather crusty. Furthermore, someone along the way tack welded the bearing buddies to the hub. So that makes removing and installing a cotter pin on the axle castle nut a real challenge. I did some measuring and lucked out that I was able to get the actual bearing numbers off both bearings. The hubs use a 67048 inner bearing and a 11949 outer bearing. Doing a little digging, I found this isn’t a very common setup. It seems that it’s used for 3500lb axles with with 13” or larger wheels. This is on a sled trailer with the typical 8” wheels. It also shows that this bearing and hub setup is used on some agricultural applications with speeds under 20 mph. It looks like there are limited, but at least some options. I was somewhat surprised to the uniqueness of this setup as I thought I’d pretty much be able to get a regular ol’ 5 lug hub and move on. Old hubs: A pic of the axle: Here’s the wheel and tire setup. This is a newer setup I was test fitting. Got a great deal on FB Marketplace.
Quick update. Ended up with a set of Dexter hubs from e-trailer. They are nice units. Unfortunately, they only came with one bearing and a race vs the two bearings. E-trailer is shipping the correct ones as we speak. Also, the studs on the new hubs are a bit short. I’ll have to get some longer ones. I’ll probably update the other trailer thread I have once I get this part of the project rolling. Pun slightly intended.
