Don't be surprised if they find nothing. The tendency now is just to align and no work spent on looking for looseness as it means they can't get the alignment money and the easiest fruit to pick. Shops typically do not look real close for loose parts any more as their prices are too high and the search work for the bad part is then wasted when customer refuses the work.
Better to get the alignment, then customer comes back complaining to get the work then and pay a second time for alignment. Backwards America like so many other things now.
