Does the steering wheel move back and forth front right to left as you start driving slow, then get faster as the speed increases? From what you describe, that is from a bent rim/wheel when you hit the curb on the right front. That is most likely also the cause of the wobbling and the shake.
Take the wheel/tire to a tire store like Goodyear, Firestone or any shop that has a tire spin balancer and tire machine to break down the tire, remove it from the rim/wheel, remove all of the wheel weights and place it on the spin balancer and spin it and see if in fact it doe wobble either side to side or up and down. If so, you need another wheel/rim. They can be straightened out but sometimes it's just as expensive as replacing it. The tire may be fine but it will still have to be checked when put on the new rim/wheel and it will also have to be balanced again.
Chances are it's not the axle but they should be able to check it as well. One good way to tell, is swap it to the rear and feel if the steering wheel stops shaking and instead the seats shake now.
