Brake drum question

[98pickupnyc]

Thanks for the reply.Well this is what i did.A friend of mine gave me a small bottle of rust prennetrating oil called trizol.This thing worked great.I squirt around the hub and mannaged to get some thru the lug nut stud holes around the drum.I let it sit for a an hour then got a 5lbs slege hammer and hammered the drum while rotating the drum in between.After a few hits the drum lossened.Took it off sanded the hub flange and the hub hold on the drum.Applied a never sieze on the hub flange and to the hub hole on the drum.Hopefully next time i wont have this problem again.
