First thing first: take it to a DIFFERENT shop than the one that did your repairs and get an inspection done. They might see something that the guys who were looking at it for a while might miss.
From the sounds of things (opinion here) if you had the subframe bolt tightened, and it still seems loose, that would be the first place to look. My money is on a bent subframe, or a damaged body mounting point.
And double check the strut mounting. Just a feeling I get readin your post a couple of times.......
Hope that this helps!
