Hey Mark, thanks for the pictures. That is a pretty interesting trailer. I can't say I have seen anything like that before on a trailer with a single leaf spring spanning the whole axle like that. It almost looks homemade or like someone used an axle or transverse leaf spring from an old car. Anyways, the hub appears to be a 4 lug idler hub, but I am afraid I can't give you any more specifics beyond that just by looking at a picture.

If you are looking to replace the spindle and hub, your best bet will be to pull one of the hubs and remove the bearings. Each bearing should have a number stamped on the edge that we can cross reference. I would also want you to confirm the hub bolt pattern. It looks like a 4 lug, but we would want to confirm that the studs are 4" apart on center.

If you can provide me with the inner and outer bearing numbers, I can tell you if we have anything. Hopefully it uses a common bearing combination, but from the looks of that trailer I am not so sure. You may end up needing more than just a hub and spindle. Feel free to send me that info when you have it and I am happy to look into it further.

Hi Jesse, Sorry for the late reply, weathers not been great. There’s only one bearing. The entire bearing and hub assembly are basically one piece. Theres one bearing with an inner and outer seal. One of the nuts is stripped and I’ll need to cut off to replace. How do I attach pics?

@MarkW You can feel free to email me more pictures [email protected]. I will tell you up front though that from the sounds of the parts you are describing, it is highly unlikely that are going to have parts for this trailer. I am happy to take a look but it sounds like this trailer uses old parts that are obsolete.
