Re: Eaton HO72/HO52 vs. 14 Bolt FF

I believe you are asking this because you want to use the slide on rotors correct? I am fairly certain the 11.5 AAM hubs are way too different. I don't know about the 02+ 10.5 hubs.

This is actually something I have been thinking about doing with my eaton because I don't want to use the Caddy calipers.

One thing for sure is that A backing plate bracket will have to be fabricated and welded to the axle housing.

As for the hubs, there are 2 possible easy routes.
1. Early Eaton axles used slide-on drums, which may work for the 02+ rotors
2. Mid 90+ 14Bolt FF axles used in some Suburbans (for sure, maybe lighter 3/4T trucks and 1 ton vans) used a slide-on drum. For the 14 bolt hubs, read below.

Here is what you need to make the 14 bolt hub work on the Eaton spindle, you will need to use a combination of an inner bearing cone for an Eaton and a Bearing race for a 14 Bolt hub. Then for the outer bearing, you will need to have the 14 Bolt hub machined to accept the Eaton outer Bearing race.

I am not the first person to try this. There are many others who have put the 14 bolt hubs on an Eaton.

edit: I just looked closer at the link you posted... If you enlarge the picture of the 14 Bolt you will see a spacer/adapter that they used to adapt the newer bracketry to the original axle. I am curious to know what they did for the hub/rotor? I checked out their web page and it doesn't say anything about the kit.
