Never having removed from the bottom, I might have stepped in it on the alignment issue. It depends on what you remove. I was thinking most people unbolt the upper control arms, in which case it would need a front-end alignment. If you disconnect the upper ball joint (has come out easy for me), you should maintain alignment. If you disconnect the lower ball joint (much harder) as one suggested (and MR4V's photos), you are leaving the spindle with the body so need to also disconnect the tie rods, though that should still maintain alignment. BTW, the $7 1000 lb wood dollies at Harbor Freight work great.
