    I have a Dually and on trips I still carry two spares. I actually am going to have a third soon because I have an extra tire and was just given an extra wheel. I really don't like being stranded. Paranoid or not, better safe than sorry when you're 1000 miles from nowhere.

    That's about what the shop near me quoted. $95/ea mounted and balanced with new valve stems. If I decide to keep what I have, I'll probably order a set of these:

    They come mounted already (which I will verify) and then I'll have my old set as spares just in case.

    I'm also going to buy one or two spare sets of bearings to keep on hand after I repack the current bearings. Did I mention I hate being stranded?

    Well I found what Randy said I would lol. It is indeed what Dexter refers to as an MHU axle, a 6000# axle that has smaller bearings making it derated to 4500#.

    Inner bearing surface on the spindle appears to be 1-3/8"

    Outer bearing surface on the spindle appears to be 1-1/4.

    I measured from the 1 inch mark because the end isn't square so I don't know how reliable it is.

    My research shows that a standard #42 spindle is 1-1/4 for the outer bearing and 1-3/4 for the inner. I can't just swap hubs but.... I might be able to adapt the spindles:

    I don't plan on it now. I'm just going to bite the bullet and get tires and repack or replace the bearings as needed. I just figured I'd update everyone on my findings.

    Bearing kit appears to be available here:

    Picture of the ID of the drum where the seal mounts for my own future reference.

    So on your axle do you have replaceable break shoes. Mine didn't that was problem number one.

    I didnt read every post. Go 8 lug ,dont look back. I did this on mine and did 4 brakes, stops better than the truck.LOL
    BUT make sure your bearing numbers are the same ,there are some wierd MOHO axles out there.

    I have another set of mobile home axles I picked up for another project, I think I'll look at the bearings in those and see what size they are. They are in better shape anyway.

    Thanks for the input guys.

    I like those 14.5" MH-type tires. Small, lots of load capacity for the size, and they are tough. Now, I'm not hauling as far as any of you guys with them, usually less than ~200 miles round trip. But, my triple-axle beaver-tail trailer handles a load quite nicely. I hauled 12K on it last time, and the tires weren't bulging much at all.
    Pretty sure all of the tires shoudn't be on the road, and I've been planning to get new ones... but man they just keep on working!

    Same here except I am hauling 15k on mine, I run 80-90 psi in them , 14 ply and they don't bulge a bit.

    Felt kinda bad for the FedEx guy today.

    I didn't really want to spend it but I certainly couldn't use the old ones! Yes that says load range H. Mounted on rims shipped to my house, 2 for $170.

    Man, those look nice. What size are they? 8-14.5 or 7-14.5? Either way, where did you find them? That's a good price.
