Hey Dan. In order to see if we have the right hubs for your trailer I am going to need some more information from you because we've got a few options.

I'll need you to pull one of your hubs and see if there are part numbers stamped into the sides of the inner and outer bearings. This would be the easiest way to identify a replacement hub but seeing as how you have a 1972 trailer your bearings might not be stamped.

If you can't read the numbers on the sides of the bearings you'll need to use a digital caliper like item # PTW80157 to measure the spindle at points B, C, and D from the diagram below.

Once you get this information go ahead and throw it into the comment box where it says Reply to Jerred H.

Hey Jerred thanks for getting back to me. I thought the electric hubs on this old girl were bad, but as it turned out it was a wiring problem at the pigtail. Once that was corrected the brakes worked fine. Thanks again I appreciate your time and I'll be in touch Dan
