Question:
What is an idler hub and how does it differ from the hubs you describe? Do all trailer hubs have an idler? If not, what is the advantage?

Expert Reply:
The Dexter Trailer Hub Assembly you referenced, part # AKIHUB-440-2-1K is known as an idler hub. An idler is a hub that is no provisions for trailer brakes. It has no brake drum.
Part # 8-276-5 is an example of a hub/ drum that has a brake drum that can be used with a brake assembly like part # 23-47.
The # AKIHUB-440-2-1K would be an acceptable replacement for an idler hub with a 4-on-4 bolt pattern that uses # L44643 inner and outer wheel bearings.
