Ford E350 XLT - rear right brake keeps getting stuck.

[skumancer]

Hey everyone. Scratching my head on what to test/replace next. I've got a 2008 E350 XLT extended that I converted to 4x4. Since before the conversion, the rear-right brake has had issues getting stuck after extended sessions of braking (coming downhill from a mountain).

I've replaced the caliper and I recently replaced the pins again as they were frozen in place after an extended period of usage and the brakes getting stupidly hot.

My thought is that I have to replace the rotor completely and maybe check the rear axle shaft for straightness. Maybe replace the caliper again or rebuild it?

Any help is appreciated!

Could be the rotors warped and calipers are grabbing and getting hot and sticking.
How many miles on the rotors?
Are the axle bearings lubed by the differential oil?
