The front end shakes when accelerating between 45-50 mph what could this be from on 2007 Hyundai Accent

I've had the allignment done and new tires put on and sometimes it feels like the front end is going to shake off. Then it seems to disappear after 50 mph

How do the axles look possible cv joint. Had this problem with a corolla, new axles 80.00 each fixed the problem.
