I don't know if you are short on money or you can swing it but bearing replacement is easy. It got to be old hat for awhile a few years abck for me between my IDI and a couple of boat trailers that were in the family. Should be a 1 hr-2 hr fix. Probably need to punch out the races as well since it overheated so much, might need the help of a machine shop for that. I was always scared to exert the neccessary violence on the ones on my truck and never had to really because they haven't been cooked like that. The traier hubs are easy, I'm not sure about punching out these races. Bad thing is the new bearings cost about $50 for the whole kit, race, bearings, seals, cotter key and crown nut. I'd replace both sides if the money is there just so you know what you've got, if not just clean the good side up and pack it with grease. Main trick tightening them down is take a huge socket or adjustable wrench nd get them just snug with everything set well, then back off just a hair and insert the cotter key and dust cap. They should be warm but not hot after a run down the road and shouldn't have much give when you jack up the truck and try to shake the wheel.
