Replacing Mobile Home Trailer Hub With a Hub that is Compatible with Standard Rims and Tires

Question:

Do you have replacement hubs for house trailer axle hubs, so i can use a regular rim and tire size?

To determine if there are compatible hubs and associated bearings to replace your current hubs to a more standard size you will have to take several precise measurements on the spindle of your axle. It is recommended to use a set of dial calipers to obtain these measurements.

You will need to measure the seal, inner bearing, and outer bearing. It is also possible that there may be bearing numbers stamped on these parts as well, and those would be helpful in obtaining the correct replacement compatible hub. I have included a photo showing these measurement locations and possible bearing numbers.

Please be aware that mobile home axles were originally intended for a single use applications. Mobile home axles are commonly used for home made trailers since they are readily available. Since mobile home axles are not intended for continued use, replacement parts and compatible conversion parts are not usually readily available.

It is possible that there may not be a compatible replacement hub that will convert your current mobile home axle to a more traditional size of hub, that can be used with standard size rims, tires and other associated replacement parts.

If you are able to get the bearing numbers, and or the measurements on the spindles, I would be happy to see if we have anything available. However, for compatibility and safety reasons it may be easier to replace your mobile home axle with a standard trailer axle, and then compatible parts would be more readily available.

I have 7-14.5 Lt Tires. With Doughnut Wheels, Rim Clamps and Nuts. [electric brakes] old trailer house, house frame cut to make a 8x18 ft trailer, carries my small tractor my hub, and lug bolts, and cover for the brakes are all one piece........can you help.....there is no numbers on the BENT hub, [hub is out of round]. Bought new tires, was told my wheel was bent, that was a lie. I can send you a pic if needed.thanks...

You honestly might need to replace the axle altogether. A lot of mobile home parts are only made to be used once, so replacement parts can be really hard to come by. If you can email me a picture separately I'd be happy to take a look. Do you by chance know what inner and outer bearings are used on the hub?

We don't have any hub assemblies that use these size bearings. Are there by chance any numbers printed inside the bearings themselves? Mobile home axles can be hard to find replacement parts for since they're technically only designed for one-time use.

@BillyE I believe i have the same axle that you have. I had no luck in finding a direct bolt on hub conversion so what im doing is getting a hub that uses the same outer bearing and a larger more standard size inner bearing. To make the larger bearing fit the spindle i am having my buddy machine me out a sleeve that will press onto the spindle to accommodate the larger inner bearing and seal. So the inner bearing and seal will ride on that sleeve instead of the spindle. Still in the process of doing this ill let you know how it comes out. Hope this helps. The inner bearing i will be using will be a 25580
