If you want to stay on good terms with the dealer you got it from, don't go there looking for a warranty job on this s/arm. Even IF the dealer replaced it for you, if he ever got wind of the circumstances of the failure, he'd fuck you at every chance he got, and rightly so. You fucked up. Now own up to it and get it fixed yourself.
Oh, and I'm glad your wife didn't get hurt during this debacle.
