Method to Figure Out the Correct Replacement Hub Assemblies


I am looking to replace the hubs on a homemade 6x10 trailer I purchased. I originally intended to get a whole new axle with hubs on it but my spring centers are 75 1/2 apart and I dont see anything in that sizing. So decided to just replace the hubs with idlers... I measured the spindles and the bearings are 1-1/4inch I.d roadside and 1-1/2 inch i.d. trailer side. Let me know if you have any suggestions. I have small welder but I dont really want to get into that. Thanks!

Thank you for the information, but a bit more specificity is needed to ensure we get you the right parts. If you wipe away the grease, you might be able to see the part number stamped directly on the bearings themselves.

If you are unable to find them, you would need to use a digital caliper and measure your spindle to the thousandths of an inch where the bearings ride. You can use the photo I've attached to see exactly where you need to measure.

I've also added a link to a help article on common bearing sizes, as well as a link to our available bearing kits.
