Zulfiqar,

Thank you for this this info. I know the shop's new Bosch alignment machine was clapped on the bead, I was there when they were finishing up. This could be a definite problem. I will discuss with them today if they have the 5 point mounting system. However, this equipment does not use the old style beam and reflector method. each wheel has a transponder that sends the data back to the center via wireless. In thinking about what I just wrote, makes me wonder, what would happen with a bent rim... Hmmm... If not, on to another shop. I will review with them the W124-zone spec sheet. This could have also been part of the problem, wrong data geometry. Another could be... new machine and lack of practice.
Unfortunately, I did not have time over the weekend to work on the car due it becoming a John Deere repair weekend instead, the grass never stops growing. I will do the inspection ball joint as you outlined this coming weekend and see if they are worn.

Thanks again!

Brian
