The cv axle goes thru the hub and is secured with that 30 mm nut in the middle, sometimes it gets corroded in there, perhaps no anti seize was put on the splines. Most times a swat with a BFG will break it loose. That can damage the cv joints in the axle, the ball joint also.
If the alignment is out, it’s either the tie rods ends worn out or the rear lower control arm bushings.
