How to Verify a Hub Fitment on a Spindle

Question:

Im replacing the hub/drum on an older trailer. I think I need part AKHD-545-2-1K, but Im not sure how to confirm itll fit my axle. Ive attached a pic, but I dont have a caliper to measure. or if you can tell me the link to a pic of the spindle shape that part fits on, great. Thx.

There isn't a spec sheet or anything of the like to verify the fitment of a hub like the Trailer Hub and Drum Assembly - 2K Axles # AKHD-545-2-1K, and there are only a couple ways to do so. You need to know the weight rating of your axle, and also what bearings your current hub has. 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 can't, you do need a digital caliper; you mentioned you don't have one so you will need to purchase one. Once you get the caliper, you will need to 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.

You also need to know your hub's wheel bolt pattern; I have added a help article which details how you can find it for sure. Knowing the bearings or the exact measurements of your spindle is truly the only way to know the fitment of any hub. I have added links to our entire selection of hubs if the one you asked about is not correct.
