IM having an issue trying to remove the front rotors

Im having an issue trying to remove the front rotors. Im replacing because it pulsates when I brake. The front bads look ok. Still have plenty on them and actually have even wear on them. I do feel a little bit of a warp to the rotors. I am able to remove everything and the rotor spins free, but cant get it out to replace!

also, when I turn to my left only, I hear like a slight burp from the car. Almost like a back fire or like I have a hole in my exhust somewhere. But I only hear this when I turn left.

THANKS!
