Overheating wheel bearing?

Mostly heat from the brakes, my 88 also had warm hubs during normal
Driving conditions.
Junk yard searches may be a way to find some hubs.
Try calling Jeff's Bronco Graveyard for hubs too.

I'm wondering if my hubs are creating the heat? By the look of them, I wouldn't be surprised if they are the originals. It turns out Warn doesn't make a replacement for my truck. My model is is '88, but the truck was built in late '87 so it has the "top hat" or "flange" style hubs. What do most people replace these with? I need to keep cost low...
Look at this kit:
1987-88 Knuckle Out Conversion-Broncograveyard.com
Now there might be a cheaper way of doing it (like getting all the parts from a junkyard!) but you can't just put regular style lockouts into tophat hubs.

I went for a longer drive yesterday, probably 15 miles. The hubs were hot, I could only keep my finger on them for a few seconds. I checked the rotors and they were too hot to touch. Both sides of the front were the same. Are the rotors getting hot from dragging brakes, or are they getting hot from the bearings? Considering the rotors were so much hotter than the hubs, I don't think I need to worry about replacing the hubs for now.

Doubt it's the bearings if the rotors were hotter than the hubs.
Did you use the brakes moderately or hard (or even lightly for a long period of time) before you checked the temperature? They heat up quick! That's how they work, by converting mechanical energy into heat.

Sounds like your calipers are not releasing all the way.
Sticking, binding, whatever. They are relatively cheap.
I would replace both calipers and flex lines as they can
brake inside and stop the brakes from releasing by not
letting the pressure to return to the master. A bad master
can cause this also. But as you don't seem to be having any
luck following the directions the guys are giving you for
trouble shooting than maybe ya should start throwing new
parts at it.
I told my boss one time that I had no brakes on the off highway
Terex I was driving. He said that I did not need brakes as they
would just slow me down.
Try opening the bleeder on one front caliper when the brake is hot.
If fluid squirts out under pressure than the brakes are not releasing.
This is an easy test bud. Please let us know when this is done.
