Well, here's my two cents.. If I curbed my car and was finding some play in the front end, I'd just replace the whole part that was damaged. I learned the hard way that when you replace one thing and try to cut a corner, that you'll end up taking it apart and doing it again. I just replaced my upper control arms with Kinetix adjustable camber arms, and have been pretty satisfied so far. I did LCA bushings last year.
Also, rule of thumb.... If you do one side, do the other as well.
Did you personally get under the car and look? It's not difficult to check for play either. Just need a pry bar and a good jack to raise the car.
