Replacement Hubs and Electric Brakes for 5,200 Pound Axle on Trailer  

Question:

I have a 2012 Storm trailer and would like to purchase new drums and brake. I have the 5000 lb axles, 6 on 5.5 bolt circle. my current outer bearing is a 15123. What is the difference between this outer bearing and the lm 67048? thank you

Helpful Expert Reply:

The Trailer Hub Bearing # 15123 and # LM67048 both feature the same 1.250 inch inner diameter, however the outer diameter differs between the two units. This essentially means they will both fit the same spindle size on a trailer, but they will work with different hubs.

To replace the hubs on your trailer that use the # 15123 outer bearing, I recommend the etrailer.com Trailer Hub and Drum Assembly # AKHD-655-6-K. This hub and drum assembly is designed for 5,200 pound axles, features a 6 on 5-1/2 inch bolt pattern, and uses the # 15123 outer bearing and # 25580 inner bearing.

Then for compatible electric brake assemblies, I recommend the etrailer.com Electric Trailer Brake Kit # AKEBRK-7-SA. These 12 inch assemblies are self-adjusting, which means they will not require periodic manual adjustments like standard brakes. Both the Left Hand and Right Hand assemblies are included.

I have attached a couple short video demonstrations on these products that you can also check out.
