i would try not to snap off anything lol.
not sure how your airbag comes off, but the after you get it off, its all gravy from there. you need a small 2 gear puller. like this. to get the wheel off after you unbolt it. dont beat on it, it wont help. you need a puller.
try youtube for a vid to help with the airbag, (thats how i figured out how to get my regals airbag off) always unhook your battery when dealing with the airbag.
