How to Determine Correct Hub Assembly Based off Bearing Numbers and Spindle Dimensions

Published 03/12/2014

Question:

I have a 2008 Aztex utility trailer needing new bearings, Aztec is out of business. I have pulled the hub which has the following ID marks stamped on it: 1 CDC within a circle company? 2 13676-4 and 3 F21102. Does any of this help ID the bearings / races needed? There is no part number on the beaings.

You will need to disassemble your hub to get the actual bearing numbers. Unfortunately the numbers you gave me don't help identify anything.

Check out the video I attached that details how to get the bearings out of a hub so that they can be identified. Once we have that info we can pick out the correct hub.

The other option you have is to get exact measurements from spindle. Check out the picture I attached shows what dimensions are needed.

I also will need to know the correct bolt pattern of the wheels on your trailer. I attached an FAQ on this as well.
