There is nothing wrong with the front end, and sadly, there never was. You've replaced lots of parts for nothing.

Your REAR wheel on the right side is out of alignment. Probably a bent subframe, but even that shouldn't prevent getting the alignment correct. Rears can be adjusted for camber and toe-in, and if they are off, the car will pull rather badly.

Have a proper four wheel alignment done by an MB shop. Have them check the condition off ALL the rear links -- dollar to a doughnut, something ain't right back there. Have them set the front toe with a proper spreader bar, too -- if they don't, it won't be right, and you will have excessive sensitivity to crosswinds.
