Why is steering wheel shaking like this (POST ALIGNMENT)

So, pre alignment, the right side suspension sounded like it was gonna fall off driving at the speeds I am in video, the alignment shop told me that the right side tie rod and cv axle were shot and busted, they showed me the parts before doing the job and I’m surprised I’m still here after driving the car the way it was 😬 anyway, post alignment, repair, the car is driving much better, but the steering wheel still shakes and sways to the right if don’t hold it (as seen in the video) they told me that car still rides a little rough and that I was gonna need new tires, what else could cause this if the suspension is seemingly okay?
