Bottom ball joint is easy

Get a spanner on one side and rest it against the wishbone, then a deep socket on the other side and loosen it off. Tap the pinch bolt out with a copper stake (or thread the nut back on a few turns) to prevent damaging the thread. Then use a big flat blade and lever the wheel bearing housing from the ball joint.
But I'd undo the ball joint last.
1. Hub nut
2. Track rod end
3. Suspension strut
4. Ball joint
The hub nut will spin regardless, either get a windy gun and buzz it off, or get a scaffold pole, a breaker bar and a friend. Hold the brakes down in the car and slacken off the hub nut.
