Take both allen bolts and the stopper bolt out, GENTLY pry where the allen bolts go. Take it out and put a light coat of grease on it. You do not need to remove the axle nut to move the carrier, but if i were you I'd pull everything and lube the carrier so you don't run into this problem again. If you still havent gotten the nut loose borrow torches from someone and heat it up good, and a pipe wrench( I know, I hate using pipewrenches in these, but if there stuck a 36" usually does the trick).
