Vibrations and Heat in back tire

[Miskeeter]

I have noticed lately that sometimes... (only sometimes) when i am driving between 35-50 mph my 250 2wd will vibrate under deceleration and acceleration. It appears to be getting worse. I have also noticed that my rear passenger side tire and hub are very hot after my truck has an episode. I initially thought it could be a stuck break, but I'm just not sure. What coud it be and how expensive will it be to fix it?

Pull the caliper off and look at the pads mine did that and one piston was stuck you will know right away as far as cost doing it yourself depends if the rotor is bad around 200 for pads and caliper. Rotor probably another 60 if it's shot but most of the time you can get them turned down for a few bucks. If the caliper is fine then I would say it's the bearing but most likely it's a piston froze up.
