It is likely you can use the Trailer Idler Hub Assembly for 3,500 lb Axles # AKIHUB-5475-35-K as it has the most common bearing and seal for 3,500 lb axles, but you'll need to verify this as we don't have any way of knowing the exact hubs that are on your trailer.

To determine if this is the right hub, you will need to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you need to use digital caliper and measure your spindle to the thousandths of an inch where the bearings and grease seal ride.

You can use the photo I've attached to see exactly where you need to measure. If this happens to not be the right hub, I have added a link to our selection for you to check out as well.
