Verify that tie rods, drag link, idler arm bushings, control arm bushings, ball joints, and track rod bushings (called brake support bushings) are all it good order before attempting to align as if any are loose it will be impossible -- it can be set, but with loose parts, it won't stay.

It is also necessary to use a spreader bar on the front tires to load them apart at the front side or the toe will be incorrect. Camber not staying put is most likely worn out control arm bushings or dead ball joints, either upper or lower. Bad upper control arm bushings will also give you fits.
