I have a 06 g coupe. My alternator pulley had a small crack in it so I bought a new pulley, pretty simple right. I can't get the old one off, I was able to get the nut off the the old pulley with an impact wrench, but now I have resulted to a pulley puller and all it did is bend the pulley to the point of nothing, what can I do? Did I miss something here? Please help

 

Maybe it's seized on there? Try some PB blaster or a torch as last resort?

 

STOP!!!
Find a rebuilder shop in your area and take the alternator to them. Guarantee that they run into the same issue all of the time.
