Replacement Hubs for Old Trailer Axle Using Timken 1380 Inner/17580 Outer Bearings
Question:
Trying to figure out which replacement hub I would need for my axle based on these bearings and seal #s. Its 4 on 4. I dont have the proper tools to measure the axle. inner- Timken 1380, outer- 17520/17580, grease seal- Victor 49334

The ID for the TImken 1380 is .875 and the 17520/17580 is .625. None of the hubs we offer are compatible with spindles that have a diameter that small.
Honestly, you'll likely have a difficult time locating replacement hubs compatible with that spindle and your best bet will be to replace the axle for one that has spindles that are compatible with readily available modern parts.
To determine the replacement axle you'll need, you'll need to find the hub face to hub face dimension as well as the spacing of the spring seats, center to center. I've provided a diagram showing these dimensions.
Given the bolt pattern, you likely have a lightweight trailer using an axle with a 2000 lb or less capacity. If that's the case, and a 57-1/2 hub face and 46-1/2 inch spring center would work for you, I'd recommend the CE Smith replacement axle part # CE33201GA. The axle has an 1800 lb capacity, and would be compatible with a 4 on 4 hub such as part # 8-91-05UC1-EZ.
Another option would be a Timbren Axle-Less suspension like # ASR1200S02 if a 1200 lb capacity would work for you. The axle-less suspension would allow you to discard the existing leaf spring suspension.
If you'd rather not go the axle-less route, if you'd care to reply with the hub face and spring seat dimension from your current axle, I'd be happy to check to see if any of the Dexter replacement axles we offer would work for you.
