Rear Rotors

I'm trying to change the rear rotor, but I can't get it off. Any ideas? I've tried a hammer and nothing works. Dodge Ram 2500

It sounds like you might be trying to loosen the wrong bolt. You don't need to mess with the big one.

yea make sure your taking off the right bolts then, use a sledge hammer and get a bit of momentum, after letting some pb blaster soak on it for a while.

my rear rotors were rusted to my axle shaft once, and that worked for me
