Finialy I got the axle nut off. I had to notch it, heat it, and bang it till it broke apart.
I tried a 2 foot breaker bar with a 6 foot cheater bar and the nut still wouldn't budge, the breaker bar ended up breaking. Good thing for lifetime warrenties.
Now, my hub assembly is loose. I'm not sure just putting on a new nut will solve the problem. Could it be wheel bearings?
