How to Pick Out Replacement Hub for Trailer that Sheared Off Studs

Question:

Hey guys, we lost a wheel on the highway due to all 8 wheel studs shearing off on our Colony Cargo trailer with 7k lbs torsion axles. Do any of the replacement brake drum/hubs work with this axle? Im unsure of how to tell what unit may work. Need to get it fixed and back to work asap. Thanks for any help!

That's pretty crazy that you ended up shearing off all 8 of your wheel studs. Normally they will break one at a time but not all together like that. This makes me wonder if maybe you were losing them all one at a time until the last few went out together.

In order to pick out the correct hub assembly for a trailer you are going to need know a few key pieces of information. The first thing you will need to know is the bolt pattern of your hubs. This is so you get a hub that is compatible with your wheels. I attached an FAQ article on determining bolt pattern for you to check out. It looks like you have an 8 on 6-1/2 inch bolt pattern though.

Next thing you will need to know is what spindle you have on your trailer. In order to do that you can either get the inner and outer bearing numbers from a hub or use a dial or digital caliper to get exact measurements of the spindle. The measurements needed are the parts of the spindle where the bearings ride.

If you get back to me with that information I will help you pick out the right hub assemblies. Or, you can follow the link I attached that will take you to the page that has all of our replacement hubs.

You would want to first select the bolt pattern that you have, next select the inner bearing you have, followed by selecting your outer bearing, and then all the correct hubs will be listed.
