Question:

Hi, I’m looking for replacement hubs for my trailer. The axle is tapered. I assume a 2k axle as it’s under a 16’ boat. The axle has a “knob” on the inside that measures 1.685 using a caliper. Then it steps down to 1.375. This is where the taper begins and tapers down to 1.255. Is this an odd axle?

The 1.375" measurement corresponds with the # LM48548. The closest thing to 1.255 I'm aware of is the # LM67048 which measures 1.250" for the inner diameter. One way or another, bearing combinations using the # LM48548 are obsolete so we do not have a hub that will fit. The best solution is to replace the axle with one that uses a modern bearing combination.

To find a replacement axle you will need the hub face to hub face measurement. I have attached a helpful video below which explains how to measure. I would also double check to see if there is an axle tag that lists the capacity since it seems like you aren't quite sure. Once you have your measurements you can choose from the following based on the length and bolt pattern:

-Trailer Axle with Idler Hubs - 4 on 4 Bolt Pattern - 60" Long - 2,000 lbs # e25GR

-Trailer Axle with Idler Hubs - 5 on 4-1/2 Bolt Pattern - 60" Long - 2,000 lbs # e84YR

-Trailer Axle with Idler Hubs - 4 on 4 Bolt Pattern - 72" Long - 2,000 lbs # e62YR

-Trailer Axle with Idler Hubs - 5 on 4-1/2 Bolt Pattern - 72" Long - 2,000 lbs # e32GR

If these lengths don't match your current axle I would try reaching out to a company like Dexter to see if they can supply you with one. The other option would be to use a universal replacement like the Timbren Axle-Less # ASR2000S02 which also upgrades and replaces your suspension.

So I could get buy with the bearing you mentioned? This hub requires lug bolts instead of nuts and I hate those. Maybe I can press lug studs into that hub depending on the size hole they require?

@Ross no, bearings are very precise so it is likely something else unless your measurement is wrong. You could measure the inside diameter of the corresponding bearing to compare and see but I'm sure it is another obsolete bearing. We have some records of 1.255" ID on old spindles but no bearing number for me to identify it with. I know nobody wants to hear "replace the axle" but it is the best option. You could weld on a new spindle but you're going to have to take it to an axle shop with the right tools to do that which means it will cost just as much or more in the end with labor.

Also, if I could read the numbers on my old bearings, it would help.
