You may have a bent spindle or even strut. I hate to say it, but I wouldn't have a whole lot of confidence in the people that you have taken it to. Most of the newer alignment machines will do most of the work for you, if you know what you are doing. The problem is, many times there are people that are doing alignments that only know how to operate the machines, not how steering/suspensions work.
They should have given you a print out of the alignment specs. If they are in color, the readings that are within specs will be GREEN. The readings that are out, are in RED. If I remember right, they also show "SAI". If that is not normal, it will tell you that you have a bent strut or spindle.
