If warranty is done they have to do it,so no they won't give you a axle to install yourself.Put on stock tires and no lift and tell the it just broke and it left you stranded.They should cover it under warr,Hopefully it didn't mess up the splines internally in the ft diff(side gears).That's unique that the inner cv jt didn't snap first(???).I know it sucks but if it's covered in the oem warranty,take it back to Honda,cv axles can be $$$$,save money and act likr you know nothing(tire bigger,lift,etc...).Take it back and wait,hopefully they're faster than the yahoo's down south...Good LUCK...
