Robert, you don't have to realign it after changing the axles. On your car you remove the nuts that hold the lower ball joint to the lower control arm and then swing the spindle out of the way.
When you reassemble and tighten those nuts back up everything is just as it was, no alingnment needed.
I do a couple of axles a week typically and for the last year the autozone have been getting lousier and lousier. I would go with the Cardone ones from Advance, they almost always have new ends on the cardone units. The very best rebuilds i've found are Laycs from California but i don't think you can get them where your at. The Crown ones from Advance or Checkers haven't been as good a quality as they used to be but the Cardone are pretty consistent.
