If the alignment was done with a worn or bad ball joint or tierod, it will never be right. 90% of alignments, the toe in/out adjustment is the only thing done. Always make sure the shop gives you the print out, showing everything 'in the green'. AAA car care, gave me the excuse, the printer ran out of ink. Guess what, I wound up going back because it was still off. The lazy tech tried to BS me and say my steering box had 'free play'. Then he used the old go to 'it may be a tire pull'. The second alignment was better. There is a guy on youtube, that shows using a tape measure and string pulled tight, to line back wheels, with the front. The string takes the place of the laser. I tried it, adjusting the tierod using measurements off the string. I adjusted the camber with a level and the rim. It drove perfect. In fact, I paid for alignment, just to see how close I got it. The tech said it was all in spec.
