I would be happy to help!

Based on your bolt pattern of 6 on 5-1/2", and one of your bearings being the # LM67048 you will more than likely need the Dexter Hub and Drum Assembly # 8-201-5UC3-EZ which is compatible with electric trailer brakes. This hub uses inner bearing # 25580 and outer bearing # LM67048 along with the 6 on 5-1/2" bolt pattern, so to make sure it will fit you will need to find the bearing number stamped in the face of your inner bearing, or measure the spindle using # PTW80157 in the location shown in the included diagram.

For electric brake assemblies you will need the # AKEBRK-7-SA, and if your current brake mounting hardware is in rough shape you will also need replacement hardware # BRKH12.

Next you will need to add a 7-way connector to your trailer using # H20046 and junction box # 38656. In addition you will need to run # 10-1-1 from each brake assembly to the junction box using heat shrink butt connectors # DW05745-5 for a weather tight connection.

To complete the wiring you will need to add a breakaway switch kit # 20099.

Lastly you will need to lockout the surge brake actuator on your trailer by using a bolt or having a qualified welder add a few tack welds to keep it from moving.

Electric trailer brakes will require your tow vehicle to have a functional 7-way connector and a trailer brake controller. If you are missing one or both of these components just let me know the Year/Make/Model of your tow vehicle and I would be happy to make a recommendation for you.

I included videos of the products mentioned for you to take a look at.
