I am looking for a rebuild kit that focuses on seals and bearings/races for everything from the spindle and outwards. The only things I can find include inner axle seals and carrier/pinion bearings. Does a rebuild kit like this exist? If so where can I buy one?

 

Hit a place like Six States distributing or any Dana Spicer supplier
Hub kits exist and bearing kits for the axle
Ask Six States what kits are available
They used to send little kits with the Warn Hubs from Ford
The 1k104 and 1k105 small parts kit for the hubs is what Ford would have offered back then which will be obsolete by now
I have tons of that stuff I was about to toss out
Post a pic of what you need, maybe I have it, which means you can have it
You can get those 4x4 spindle bearings anywhere like autozone, and they come with the little seal most of the time

 

Check Bronco Graveyard. That is where I got mine.

 

East Coast Gear Supply has a "Dana 60 corner" with most of what you're looking for
