piviot ball stuck in lower arm

Ok i got the pillow ball out, that guy just used a drill and it came out. So i went home an i tried to get the upper arm off but the hinge pin was stuck REAL GOOD! it took some baby oil, vice grips, and some pliers to get it out. i thought it was just the hinge pin that was bent but it is also the arm! i cant get a hinge pin through the holes cause they dont line up. I'm a bit dissapointed cause i havent ran them much and i didnt think that a FLM arm would bend in that crash. Whats the warrenty on them? isnt it $8 for a new one? I cant really remember if you have to send it back? hope not cause it will cost me about $15 to send it cause i live overseas.
